How To Design LED Ring PCB?

The process of LED ring PCB design involves several steps:

1. Define Your Requirements and Specifications

The first step in any PCB design is to define your needs and specifications. For LED ring PCBs, this includes determining several key factors:

  • Size and Shape: The size of the LED ring PCB will be dictated by the physical space available in your project. Are you creating a large display, a compact wearable device, or a decorative lighting solution? This will determine the diameter of your PCB and the number of LEDs to be used.
  • LED Configuration: Decide on how many LEDs you want to arrange in the circle. The number of LEDs will influence the brightness and uniformity of the light emitted by the ring. Be sure to space the LEDs evenly for consistent light distribution.
  • Power Requirements: LEDs require a specific amount of voltage and current. Determine the power requirements of the LEDs you plan to use. Ensure the PCB is capable of supplying the necessary power to each LED without overheating or causing circuit instability.
  • Type of LED: LED ring PCBs can house different types of LEDs, such as standard SMD (Surface-Mount Device) LEDs, high-power LEDs, or flexible LEDs. Your choice of LED type will affect the overall design of the PCB.
  • Voltage and Current Considerations: Ensure the voltage and current ratings match the specifications for both your LED ring and the power supply. Consider using a constant current driver to regulate the current supplied to the LEDs, preventing power fluctuations.

2. Select the Right Materials for Your PCB

The materials you choose for your LED ring PCB will significantly affect the performance of the final product. Here are the most commonly used materials:

  • FR4 (Glass-Fiber Epoxy): This is the most common material used in PCB manufacturing. It’s affordable, durable, and suitable for general lighting applications. FR4 is ideal for low to medium power LEDs.
  • Aluminum (Metal Core PCB): For high-power LEDs, aluminum is often used as the base material for the PCB. Aluminum offers superior heat dissipation, preventing the LEDs from overheating and ensuring they operate at peak efficiency. Aluminum-based LED PCBs are commonly used in industrial or automotive applications.
  • Copper: Copper is another material used in LED ring PCBs for its excellent thermal conductivity. Copper-based designs help to quickly dissipate heat generated by high-power LEDs, keeping the system stable and extending its lifespan.
  • Polyimide: For flexible LED ring PCBs, polyimide is a preferred material. It is flexible, durable, and resistant to high temperatures, which makes it ideal for applications that require bending or shaping, such as wearable devices or automotive lighting.

3. Create the Circuit Design and Layout

Once you’ve defined your specifications and chosen the materials, it’s time to create the circuit layout. This is where the technical aspects of your LED ring PCB come into play:

LED Placement: The most important aspect of your design is the placement of the LEDs in a circular configuration. Ensure that the LEDs are evenly spaced to ensure uniform light output. If you’re using high-density LEDs, make sure to account for the necessary spacing to prevent heat buildup.

  • Power Distribution: Plan the power distribution for your LED ring. You must ensure that each LED gets the correct amount of power. For larger designs, consider creating multiple power supply points around the ring to avoid voltage drops and ensure each LED is supplied with stable power.
  • Current Control: In most LED applications, a constant current driver is used to regulate the current flowing through the LEDs. This helps maintain consistent brightness and prevents damage to the LEDs. Design the circuit to include appropriate resistors or constant current drivers to manage power flow effectively.
  • Heat Dissipation: LEDs generate heat, so effective heat management is a crucial part of the design. Ensure that your PCB layout includes a clear path for heat dissipation. If you’re using metal-core PCBs, the aluminum or copper material will help carry away heat, but proper trace widths and vias are essential to enhance the thermal conductivity.
  • Trace Widths and Via Sizes: Calculating the correct trace width and via size is critical for ensuring that the PCB can handle the required current without overheating. Use PCB design software that can help you calculate trace widths based on the current requirements for your LEDs.

4. Consider Power Supply and Drivers

The power supply is a key consideration in LED PCB design. LED rings require a regulated power supply to provide a consistent voltage and current to the LEDs. Here’s what you need to think about:

  • Power Supply Type: Depending on the voltage and current requirements of your LED ring, you’ll need to select an appropriate power supply. A common solution is using a constant current driver, which adjusts the current flowing to the LEDs to ensure that they don’t receive too much power, which could lead to burnout.
  • Voltage Regulation: Ensure that the power supply can deliver a constant voltage that matches the voltage requirement of your LEDs. Many LEDs operate on low voltage, and using a higher voltage power supply without regulation could cause instability.
  • Efficiency Considerations: LED drivers and power supplies should be as efficient as possible to minimize energy loss. Look for energy-efficient drivers that can help you reduce power consumption, which is especially important in battery-powered or low-power applications.

5. Prototype and Test Your LED Ring PCB

Once your design is complete, the next step is to prototype your LED ring PCB. This stage involves manufacturing a small batch or a single unit of your design for testing. LED Ring PCB Prototyping is essential for checking the functionality of the circuit, ensuring the LED ring lights up correctly, and verifying that the power distribution is stable.

Here’s how to proceed:

  • Manufacturing the Prototype: After designing the PCB, the next step is to send the design files to a PCB manufacturer for production. The manufacturer will produce the prototype based on the materials, size, and specifications you’ve provided.
  • Testing the Prototype: Once you receive your prototype, it’s time to test it. Check that all LEDs light up as expected, and that there are no issues with flickering or uneven light. Verify that the power distribution works well and that the PCB doesn’t overheat.
  • Thermal Testing: For high-power designs, thermal testing is crucial. Monitor the temperature of the LEDs during operation to ensure that the heat dissipation is working correctly. If the PCB gets too hot, you may need to make adjustments to the trace widths, vias, or use a more efficient heat sink material.
  • Adjustments and Iterations: Based on the results of your testing, you may need to make design adjustments. This might involve tweaking the power distribution, changing materials, or adjusting the size of certain components.

6. Move to Mass Production

Once the prototype has been successfully tested and approved, you can move on to mass production. Working with a reliable LED PCB manufacturer is key at this stage to ensure that the final product meets all of your quality and design specifications.

OEM Aluminum Backed PCB Manufacturer

March 12th, 2025

If you’re designing high-performance electronics, you’ve probably heard about aluminum-backed PCBs. These boards are not just a trend—they’re solving real-world problems in industries like LED lighting, automotive, and power supplies. Let’s break down what makes them unique and why they might be the perfect fit for your next project.

What Is an Aluminum Backed PCB?

An aluminum-backed PCB (printed circuit board) is a type of metal-core PCB (MCPCB) that uses an aluminum substrate instead of a traditional FR4 base. This layer acts as a heat sink, pulling heat away from components. The design typically includes a dielectric layer, copper circuit layer, and aluminum substrate. Perfect for high-heat applications!

  • Copper Circuit Layer – The top layer, made of copper foil, is used for electrical connections and signal transmission. The copper thickness varies from 1oz to 10oz, depending on current requirements.
  • Dielectric Layer – A thermally conductive but electrically insulating material separates the copper from the aluminum base. The dielectric layer thickness typically ranges from 75”m to 200”m, balancing insulation and thermal transfer.
  • Aluminum Base – This metal substrate serves as a heat sink, drawing heat away from active components. The most common thickness is 1.6mm, though variations from 0.2mm to 3mm exist for different applications.

Aluminum PCB vs. FR4 PCB: Which Wins?

FR4 (fiberglass) PCBs are commonly used in consumer electronics, but aluminum-backed boards shine where heat matters. When choosing between aluminum PCBs and FR4 PCBs, key differences must be considered. The table below highlights critical factors that differentiate them:

ParameterAluminum PCBFR4 PCB
Thermal Conductivity1.0–8.0 W/m·K (varies by dielectric material)0.3–0.5 W/m·K
Thermal Expansion5–20 ppm/°C (closer to copper)14–18 ppm/°C
Heat DissipationExcellent, reduces hot spots  Poor (requires external cooling)
Mechanical StrengthExcellent due to metal baseModerate
Electrical PerformanceConsistent, stableCan degrade under high temperature
WeightHeavier than FR4Lighter
CostHigher due to metal substrateLower
(Aluminum PCB vs. FR4 PCB)

Note:

  • Aluminum conducts heat 8-10 times better than FR4. No more fried components!
  • Aluminum resists bending and cracking. FR4 can warp under stress.
  • FR4 is cheaper for simple designs. Aluminum saves money long-term by reducing cooling needs.
  • Aluminum PCBs last longer in high-temperature environments.
  • Choose FR4 for low-cost, low-power projects. Go aluminum for heat-heavy applications like LEDs or power converters.

Types of Aluminum Backed PCBs

Aluminum PCB can be divided into several types according to layer counts or used materials. But they commonly classified by layers:

1. Single-Layer Aluminum PCB

    Single layer aluminum backed PCB comprises a single conductive copper layer, a dielectric, and an aluminum substrate.

    1 layer Aluminum-Backed PCB stack up

    It always called single sided aluminum PCB due to it only has one layer copper trace. It is the simplest metal core PCB design, and it cost-effective due to simple manufacturing. Commonly used in daily LED lighting like swimming pool lighting, office lighting, street lighting


    2. Double-Layer Aluminum PCB

    It has two conductive copper layers, generally separated by the aluminum base. But in another case, both the two copper layers can be located on the top of aluminum base, separated by an insulating layer. It can be called single sided two layers aluminum PCB if made in this way.

    2 layer Aluminum-Backed PCB stack up

    The double layer aluminum PCB provides higher circuit density and improved overall electrical performance. They are commonly used in high power devices where required better heat dissipation like automotive electronics, industrial power modules, and motor control applications.

    3. Multilayer Aluminum PCB

    Different with multi-layer FR4 PCB, the multi-layer aluminum PCB consists of multiple layers of copper and dielectric materials stacked over the aluminum base. Please see its stack-up as following (4 layers aluminum PCB as example):

    multilayer Aluminum-Backed PCB stackup

    It has more complex circuit designs and is used in high-performance applications such as telecommunication systems and aerospace electronics. Multilayer aluminum backed PCB is rarely used and difficult to manufacture because it requires advanced manufacturing techniques for precise layer alignment and thermal control.

    How Thick Is an Aluminum PCB?

    Aluminum PCBs come in various thicknesses depending on the application. The most commonly used thickness values are:

    • Standard (1.0–1.6 mm): Common in LED lighting and consumer electronics. Lightweight and cost-effective.
    • High-Power (2.0–3.0 mm): Used in industrial machinery or EV battery systems. Handles extreme heat and mechanical stress.
    • Custom Thickness: Some manufacturers offer tailored solutions. For example, 0.8 mm boards for ultra-slim devices.

    Thicker boards improve heat dissipation but increase weight and cost. If it is uncertain, work with your supplier to find the sweet spot.

    Why Aluminum PCBs Are Perfect for LED Applications?

    Since LEDs generate large heat when working, if unchecked or not install a heat sink, it is easily to shorten their lifespan and dims their output. As a result, aluminum-backed PCBs are widely used in LED lighting as a heat sink. Aluminum PCBs solve this elegantly:

    • Cooler LEDs: The aluminum base pulls heat away instantly, keeping junctions 20–30% cooler than FR4.
    • Brighter Output: Stable temperatures prevent “lumen depreciation,” ensuring consistent brightness for years.
    • Lightweight and Compact: Eliminates bulky heat sinks. reducing size and weight. Enables sleek fixtures for homes, cars, or streetlights.

    What Temperature Can an Aluminum PCB Withstand?

    Most aluminum PCBs handle -55°C to 150°C in a continuous operating temperature. In a short-term peak, it can up to 250°C for limited durations (Please do not try this easily unless you have communicated with your supplier about its maximum temperature). Specialized designs with ceramic-filled dielectrics withstand up to 300°C. Key factors affect its temperature resistance including:

    • Dielectric Material: Determines thermal stability and thermal conductivity. Polyimide-based dielectrics excel in extreme heat.
    • Component Limits: Even if the board survives, parts like ICs may fail. Always perform FAI (first article inspection) test after full assemblies.

    For applications like engine control units or industrial heaters, verify specs with your manufacturer.

    What Is the Difference Between Copper and Aluminum PCBs?

    Copper is the gold standard for conductivity, but aluminum offers unique advantages:

    • Thermal Conductivity: Copper (385 W/m.K) beats aluminum (200 W/m.K), but aluminum is lighter and 30% cheaper.
    • Weight: Aluminum is 60% lighter. Critical for drones, EVs, or satellites.
    • Cost: Aluminum reduces material and cooling costs. Ideal for high-volume LED or consumer products.

    Copper core PCB is a go-to choice for ultra-high-power RF systems, high-power converters, aerospace, while aluminum PCB is suitable for cost-sensitive, weight-conscious designs. Though copper PCBs offer superior thermal conductivity, aluminum PCBs provide a cost-effective solution with sufficient heat dissipation for most high-power applications.

    What Is the Cost of an Aluminum Backed PCB?

    The cost of an aluminum PCB varies based on layer count, dielectric thickness, and processing complexity.

    • Single-Layer Aluminum PCBs: $5–$15 per unit (for standard LED applications).
    • Double-Layer Aluminum PCBs: $15–$50 per unit.
    • Multilayer Aluminum PCBs: $50–$200 per unit, depending on design complexity.
    • Size: A 100x100mm board costs 2–10. Larger sizes increase material use.
    • Copper Weight: Heavy copper (4+ oz) adds 15–25% to the price.
    • Volume: Ordering 1,000+ units cuts costs by 40–50% through bulk discounts.

    Despite their higher initial cost compared to FR4 PCBs, aluminum-backed PCBs eliminate the need for external heat sinks, offering long-term cost efficiency.

    Manufacturing Considerations for Aluminum Backed PCBs

    Producing aluminum-backed PCBs requires specialized techniques and strict process control to ensure mechanical strength, thermal efficiency, and electrical reliability. The following factors play a crucial role in the manufacturing process:

    1. Material Selection

    The commonly aluminum base used in industry are 6061, 5052, or 1060 aluminum alloys, each has unique properties. For example, 6061 aluminum has excellent hardness while 5052 is excel in solderability. In addition to this, dielectric material is important since it determines heat dissipation efficiency. Common materials include epoxy, polyimide, and ceramic-filled polymers, offering 1.0 W/m·K to 8.0 W/m·K.

    2. Copper Etching

    Aluminum PCBs require precision etching due to the thickness of copper layers. Thicker copper layers (>3 oz) require extended etching time and precise chemical control to maintain circuit integrity. Therefore, high-resolution etching equipment is essential to achieve fine-pitch designs and uniformity without excessive undercutting.

    3. Drilling and Machining

    Due to the hardness of the metal base, carbide or diamond-coated drill bits are used to prevent rapid tool wear and reduce burr formation. Meanwhile, high-speed drilling with controlled feed rates is necessary to avoid damaging the dielectric and copper layers.

    4. Insulation and Dielectric Layer Bonding

    Layers must adhere without air bubbles. Poor bonding causes delamination under heat.

    5. Surface Finishing

    HASL (cheap) or ENIG (premium) protect copper from oxidation.

    6. Thermal Via Implementation

    For multilayer aluminum-backed PCBs, filled or plugged thermal vias improve thermal conductivity while preventing solder migration. Via-in-pad technology enhances heat dissipation for high-power components like MOSFETs and LEDs.

    PCB Design And Fabrication, What Is PCB Design Process?

    March 12th, 2025

    PCB design and fabrication are key steps in producing functional circuit boards for various applications. From simple gadgets to advanced industrial systems, well-designed PCBs ensure performance and reliability. But how does the process work? What factors should designers and manufacturers consider? Let’s dive into the details and uncover the essentials of PCB design and fabrication.

    PCB Design And Fabrication, What Is PCB Design Process?

    What is the basic rule of PCB design?

    Designing a PCB requires precision and adherence to industry best practices. The fundamental rules include:

    • ‌Component Placement‌: Place components logically to ensure minimal signal interference and easy routing. Keep high-speed signals short and direct to reduce noise and improve signal integrity. Group related components together to form functional modules for better organization and easier troubleshooting.
    • ‌Trace Routing‌: Avoid sharp 90-degree angles to minimize signal reflection and interference; use smooth curves or 45-degree angles instead. Keep trace lengths as short as possible, especially for high-speed signals, to reduce signal degradation. Maintain consistent trace widths to ensure even current distribution and minimize impedance variations.
    • ‌Power and Ground Planes‌: Maintain a solid ground plane to improve signal integrity and reduce electromagnetic interference (EMI). Use power planes to provide a stable voltage supply and reduce power distribution impedance. Ensure proper decoupling of power supplies to minimize noise and improve circuit performance.
    • ‌Thermal Management‌: Distribute heat-sensitive components wisely to avoid overheating. Incorporate thermal vias and heat sinks as needed to improve heat dissipation.
    • ‌Spacing and Clearance‌: Ensure proper spacing between traces to avoid short circuits and maintain electrical performance. Adhere to manufacturer-recommended clearances for components and traces to ensure manufacturability.
    • ‌Layer Stackup‌: Choose an appropriate stack-up structure based on the board’s complexity and signal requirements. Properly arrange power planes, ground planes, and signal layers to minimize cross-talk and improve signal integrity.
    • ‌Impedance Matching‌: For high-speed signals, ensure transmission lines match the load impedance to reduce signal reflection and loss. Use controlled impedance traces and terminations as needed to maintain signal integrity.
    • ‌Manufacturability and Testability‌: Design with ease of manufacturing and testing in mind, such as incorporating test points and following the fabricator’s process requirements. Use standard component packages and footprints to ensure compatibility with automated assembly equipment.

    ‌In summary, following these basic rules can help designers create PCBs that are functionally optimized, reliable, and manufacturable. At the same time, designers should also flexibly adjust and optimize their design strategies based on specific application requirements and manufacturing process requirements.

    Which tool is used to design PCB?

    Several PCB design software tools are available, each offering unique features tailored to different needs. Some of the most widely used tools include:

    • Altium Designer – Offers an extensive feature set for complex PCB designs and simulation.
    • Eagle – A popular choice among both beginners and professionals for its intuitive interface.
    • KiCad – An open-source software that provides flexibility and customization.
    • OrCAD – Suitable for high-speed and multilayer PCB designs.
    • Pads PCB – A professional tool ideal for production-oriented PCB layouts.

    Choosing the right tool depends on factors such as project complexity, budget, and ease of use.

    pcb design and fabrication

    How do you draw a PCB design?

    Creating a PCB design involves multiple stages, each requiring attention to detail:

    • Schematic Capture: The first step is drawing the schematic diagram, defining electrical connections between components.
    • Component Selection: Choosing appropriate components based on electrical and thermal requirements.
    • PCB Layout: Placing components in a way that minimizes signal interference and optimizes performance.

    Rigid Flex PCB Design, Prototype&Rigid Flex PCB Manufacturer

    March 11th, 2025

    The birth and development of FPC (Flexible Printed Circuit) and PCB (Printed Circuit Board) have given rise to a new product called the rigid flex PCB. Therefore, a flexible-rigid combination board is a circuit board that combines a flexible circuit with a rigid circuit through processes such as lamination, according to relevant technical requirements, resulting in a circuit board that possesses both the characteristics of FPC and PCB.

    What Is Rigid Flex PCB?

    A rigid flex PCB is a composite type of circuit board that combines flexible printed circuit boards (FPC) with rigid printed circuit boards (PCB) through specific processes. It integrates the flexibility of FPC and the rigidity of PCB, possessing both characteristics of FPC and PCB. It can be folded or bent to reduce space occupation and can solder complex components, offering higher stability and reliability.

Please feel free to contact us at sales@bestpcbs.com if you have any request for rigid flex PCB.

    Rigid Flex PCB Layer Stackup

    1. Basic layered architecture

    The stacked structure of the rigid-flexible board achieves functional partitioning through the alternating combination of rigid materials and flexible materials:

    • ‌Outer rigid layer‌: Usually uses FR4 fiberglass board to provide mechanical support and component installation stability, while achieving electrical isolation‌.
    • ‌Intermediate flexible layer‌: It is composed of polyimide (PI) film or polyester (PET), and is combined with rolled & annealed copper or electrolytic copper to form a conductive line to achieve bending connection function‌.
    • ‌Adhesive layer‌: Use thermosetting adhesive (such as epoxy resin) or low-flow adhesive semi-cured sheet to seamlessly combine the rigid layer and the flexible layer to enhance structural stability‌.
    • Typical example:

    Five-layer structure (5-4-1 type): outer rigid board → thermosetting adhesive → inner electrical layer rigid board → thermosetting adhesive → middle signal layer flexible board → thermosetting adhesive → outer rigid board

    Four-layer structure: double-layer FPC substrate + gold finger interface + FR4 filling area + hollow layered design, taking into account plug-in stability and flexibility.

    2. Material configuration and function

    • Rigid substrate

    FR4 fiberglass board: high temperature resistance, good insulation, thickness 0.2–3.2 mm, used for support and heat dissipation.

    • Flexible substrate

    Structural features: There is a conductive circuit layer on only one side, and the other side is covered with a substrate or insulating ink, which is transparent under strong light (excluding special process requirements).


    Application scenarios: Simple circuit connection scenarios, such as low-complexity sensor modules.

    • Double-sided board

    Structural features: There are conductive circuit layers on both sides, and the electrical connection between layers is achieved through metallized holes (PTH holes).

    Application scenarios: General electronic devices, such as basic communication modules.

    • Multi-layer board

    Definition: 3 or more circuit layers are superimposed through a “sandwich” structure, combining rigid substrates with flexible substrates.

    Typical layer range: 4, 6, and 8 layers are common, and high-complexity designs can reach 12 or more layers.

    Rigid Flex PCB Layer Stackup

    What Are the Advantages of Rigid Flex PCB?

    • Space optimization and lightweight design

    Space saving: Through the integrated design of flexible circuits and rigid circuits, the connection requirements of traditional hard boards and flexible boards are reduced, and the space utilization rate is optimized.

    Light weight: The weight of flexible materials is only about 10% of that of hard boards, which greatly reduces the overall weight of the equipment.

    Shrinkage: Supports three-dimensional folding design, suitable for miniaturized products such as wearable devices and folding screen mobile phones.

    • Improved reliability

    Reduce connection point failures: The integrated structure of the whole board reduces the risk of poor welding or connector failure and improves long-term stability.

    Environmental impact resistance: Resistant to high and low temperatures (-55℃~125℃), chemical corrosion and ultraviolet rays, suitable for harsh environments such as automotive electronics and aerospace.

    Vibration resistance: The flexible area can absorb mechanical resonance and reduce the impact of vibration and impact on components.

    • Cost-effectiveness

    Reduce assembly costs: Reduce the number of connectors, simplify the production process, and reduce labor and procurement costs.

    Reduce maintenance costs: High reliability design extends product life and reduces the frequency of later repairs.

    • Signal and heat dissipation performance optimization

    ‌Signal integrity‌: Short transmission path and controlled impedance reduce signal attenuation and support high-speed data transmission (such as industrial camera image processing).

    ‌EMC performance enhancement‌: The shielding design of the flexible area reduces electromagnetic interference (EMI) and improves the ability to resist radio frequency interference.

    ‌High heat dissipation efficiency‌: By extending the copper layer area, the heat dissipation path is expanded and the thermal resistance is reduced, which is suitable for high-power equipment.

    • Structural flexibility and multi-functional integration

    ‌Dynamic bending design‌: Foldable and curled, adaptable to complex spatial layout (such as laser radar, medical endoscope)

    ‌High-density wiring‌: HDI technology (blind vias, buried vias) supports multi-layer signal layer and power layer integration to meet complex circuit requirements.

    ‌Multi-functional adaptation‌: The flexible area and the rigid area are freely combined, compatible with complex component installation and dynamic mechanical structure.

    • ‌Production and design advantages

    ‌Simplified assembly process‌: Reduce the use of cables and connectors and reduce the assembly error rate.

    ‌Design freedom‌: Supports three-dimensional wiring and flexibly matches different device forms (such as hearing aids and folding screen hinges.

    Through material and process innovation, the rigid-flexible board has achieved breakthroughs in space, reliability, cost and performance, becoming a core solution for high-tech fields such as consumer electronics, automobiles, and medical care.

    advantages of rigid flex pcb

    What Are the Advantages of Rigid Flex PCB?

    Rigid-Flex PCB Design Guidelines

    1. Preliminary planning and tool configuration

    Definition of stack structure:

    • Use EDA tools such as Altium Designer to define rigid and flexible layers through the stack manager (shortcut D+K), and check the “Is Flex” property to divide the soft and hard areas.

    Panel Division and Area Locking:

    • Use “dividing line” (shortcut D+S) to divide the board surface, fix the rigid area through the 3D lock function, and retain the dynamic bending characteristics of the flexible area.

    2. Three-dimensional layout and structural design

    3D modeling verification

    • Enable 3D view in EDA tools, simulate folding paths and bending radii, ensure that the direction of flexible region lines is perpendicular to the bending axis, reduce stress concentration.
    • It is forbidden to place vias in the dynamic bending area, and the vias should be kept away from the soft and hard combination area ≄ 50mil (high reliability scenarios ≄ 70mil).

    Material matching and stacking

    • The flexible area selects rolled copper (with excellent ductility) as the conductive layer, with a thickness of 12-35ÎŒm; the cover film (Coverlay) uses PI material, with a thickness of 12.7-127ÎŒm.
    • The hard plate area is pressed with PP glue (semi-cured sheet) and the flexible plate, and the hollow layered design is used to reduce the bending stress.

    3. Routing and through hole design rules

    Circuit Optimization

    • The flexible region conductors use a teardrop transition, with the width maximized (≄4mil), evenly distributed to disperse stress.
    • Signal lines are preferred to be perpendicular to the bending direction, and multi-layer cross-wiring uses an ‘I-Beam’ structure to enhance fatigue resistance.

    Transition Area Treatment

    • At the junction of rigid and flexible sections, the circuit transitions smoothly to avoid right angles or through-hole (PTH) design; the cover film must have a 0.5–1mm excess for overflow when opening windows.
    • Stainless steel stiffener strips or PI stiffener films are added on both sides of the bending area to enhance mechanical support.

    4. Verification and Production Alignment

    Simulation and Test Rules

    • Verify impedance continuity through TDR testing, with dynamic bending areas requiring more than 100,000 cycles of simulation.
    • Use tools such as Mentor Xpedition for lamination simulation to check the risk of glue overflow.

    Production File Output

    • Provide layered Gerber files, marking the boundaries of soft and hard regions and the positions of stiffener. CAM engineers need to handle parameters for inner shrinkage due to glue overflow.
    • Laser cutting parameters for rigid board areas must be precisely controlled in depth to avoid damaging internal layers.

    The design of flexible-hard combination boards should combine three-dimensional simulation, material properties, and process limitations, achieving high-density interconnection and reliability balance through layered lamination and dynamic bending rules.

    Rigid Flex PCB Manufacturing Process

     1. Material preparation and inner layer production

    • Cutting and drilling

    Cutting: Cut the substrate (FR4, PI film, etc.) according to the design parameters, adjust the equipment parameters and clean the surface of the board.

    Drilling: Use laser or mechanical drilling technology to make through holes (PTH) or blind holes. The hard board area needs to be cut with controlled depth to avoid damaging the inner layer circuit.

    • Inner layer circuit formation

    Pressure dry film and exposure: Press dry film on the copper clad board, and define the circuit pattern through film alignment exposure.

    Development and etching: Develop to remove the unexposed dry film, and the acid etching solution dissolves the unprotected copper layer to form a conductive circuit.

    2. Rigid-flexible lamination

    • Flexible layer processing

    Apply cover film: Apply polyimide (PI) cover film to the circuit layer in the flexible area (such as L3/L4), and check bubbles and fitting accuracy after pre-pressing and fixing. ‌

    Stiffener and protection‌: Stainless steel stiffener strips or PI reinforcement film are added on both sides of the bending area to improve mechanical strength‌.

    • ‌Multilayer lamination‌

    ‌Lamination and lamination‌: The flexible board (FPC) and the rigid board (PCB) are alternately laminated through PP glue (semi-cured sheet), and high-temperature lamination is formed into a “sandwich” structure to eliminate the risk of delamination‌.

    ‌Hollow design‌: The dynamic bending area adopts a hollow layering process to reduce stress concentration‌.

    3. ‌Outer layer processing and hole metallization‌

    • Secondary drilling and hole processing‌

    ‌Laser cutting‌: The outer layer of the hard board area is exposed to the flexible area through laser uncovering (gong edge), and the cutting depth is controlled to avoid damaging the inner layer circuit‌.

    ‌Copper deposition and copper plating‌: Chemical copper deposition in the hole is used to achieve conduction, and the outer layer is electroplated with a thickened copper layer (12–35ÎŒm) to improve the conductivity reliability‌.

    • Outer layer circuit production‌

    ‌Graphic transfer‌: The outer copper clad laminate is exposed, developed, and etched to form surface circuits, and the teardrop-shaped pad design enhances the connection strength‌.

    4. ‌Surface treatment and molding‌

    • ‌Solder mask and character printing‌

    ‌Solder mask (green oil): Print photosensitive solder mask ink to cover non-welding areas and form an insulating protective layer after curing‌.

    ‌Silk screen text‌: Mark component location, product model and other information‌.

    • Surface metallization‌

    ‌Electronic nickel immersion gold (ENIG): Chemical nickel-gold plating in the pad area to prevent oxidation and improve welding performance‌.

    • Molding and testing‌

    ‌Edge and punching‌: Cut the shape to remove excess waste and retain the functional area‌.

    ‌Reliability test‌:

    ‌Electrical test‌: Verify continuity and impedance continuity‌.

    ‌Bending test‌: Simulate dynamic bending for more than 100,000 times to detect the risk of breakage or delamination‌.

    5. Special process adaptation

    • High-frequency signal optimization: high-frequency boards (such as Rogers) are combined with blind and buried hole design to reduce signal attenuation.
    • Automotive grade requirements: pass vibration and high and low temperature cycle tests (-55℃~125℃), and add FR4 reinforcement to the hard board area.

    The production of soft and hard boards requires precise control of material matching and process parameters (such as temperature and pressure), and through multi-layer lamination and dynamic bending optimization, it meets the lightweight and reliability requirements of high-density electronic equipment.

    What Is the Difference Between Rigid Flex PCB and Flex PCB?


    Differences in materials and structures

    ‌‌Flex PCB

    • Substrate‌: Single or double-layer PI or PET film
    • Single or multi-layer flexible circuit, without rigid support
    • Usually without stiffener

    ‌Rigid-flex PCB

    • Substrate‌: The rigid area uses FR4 or high-frequency plates, the flexible area uses PI film, and is bonded with PP adhesive (semi-cured sheet).
    • Mixed structure with 3 or more layers, including blind hole/buried hole design, interconnecting rigid and flexible areas
    • Stainless steel stiffener strips or PI reinforcement film need to be added in the bending area.

    Differences in design and manufacturing process‌

    ‌Rigid-flex PCB board‌:

    • Lamination difficulties‌: Precise control of the thickness matching of the rigid-flexible area is required to avoid delamination (such as hollow delamination process).
    • Hole processing‌: Vias are prohibited in the dynamic bending area, and a smooth circuit design is required in the rigid-flexible transition area.
    • Special process‌: Laser cutting of the rigid board area to retain the flexible area, copper plating to ensure conduction.

    Comparison of performance and application scenarios‌


    ‌Flexible board

    • Low mechanical strength, easily damaged by external forces.
    • High-frequency signals are easily attenuated (affected by bending).
    • Low cost (suitable for mass production)
    • Used in consumer electronics (headphones, smart watches).


    Rigid-flexible board

    • The rigid area can integrate high-speed signal layer, impedance control is more precise
    • High cost (complex process, low yield)
    • Used in high reliability areas (aerospace, automotive radar)

    What Are the Applications of Rigid Flex PCB?

    The versatility of rigid flex PCBs makes them essential in various industries:

    • Consumer Electronics-Used in smartphones, foldable devices, and wearables.
    • Medical Devices-Applied in implants, imaging systems, and diagnostic tools.
    • Automotive Electronics-Integrated into advanced driver-assistance systems (ADAS) and infotainment.   
    • Aerospace & Defense-Utilized in satellite systems, avionics, and military-grade equipment.
    • Industrial Equipment-Found in robotics, control systems, and automation devices.

    A well-designed rigid flex PCB enhances performance, reliability, and space efficiency in modern electronic applications. Selecting the right manufacturer ensures high-quality production and long-term durability.

    ‌Conclusion

    As an integrated carrier of rigid-flexible synergy, the rigid-flexible board is driving electronic devices to iterate towards higher integration and stronger reliability with its unique structural design and performance advantages. In the industrial and medical fields, the precise design of the rigid-flexible transition zone (such as the hollow layering process) has achieved stable signal transmission and vibration resistance in complex environments for equipment such as endoscopes and vehicle-mounted radars; in the consumer electronics field, the rigid-flexible board has broken through the space limitations of traditional rigid boards with its high-density wiring and dynamic bending characteristics (≄100,000 cycle life) in folding screen hinges and mobile phone camera modules.

    From the perspective of technological evolution, the material innovation (such as the combination of high-frequency FR4 and ultra-thin PI film) and process upgrade (laser cutting precision control) of the rigid-flexible board will continue to promote its application in high-frequency and high-speed scenarios, such as 5G millimeter wave communications and autonomous driving sensors. At the same time, it significantly improves the reliability of the system-level package (SiP) by reducing connector solder joints and optimizing the rigid-flexible transition zone line design (teardrop-shaped wires and reinforcement strips).

    In the future, with the popularization of wearable devices and IoT terminals, the soft-hard combination board will be more deeply integrated into the design philosophy of “rigid-flexible symbiosis” – the rigid area carries the computing core, and the flexible area achieves form adaptation. Ultimately, in the “soft-hard game” of the electronics industry, it will become the ultimate solution to balance function, cost and reliability.

    How Long Is NFC Antenna Cable?

    A typical NFC antenna cable is usually around 75mm long, although this can vary depending on the specific antenna design and manufacturer; many commercially available NFC antennas come with a cable length explicitly stated as 75mm. Longer cables may experience higher resistance and energy dissipation, requiring careful impedance matching for efficient signal transfer.

    • Short Cables (50–100 mm): Found in smartphones, smart cards, and wearable devices to minimize resistance.
    • Medium-Length Cables (100–300 mm): Used in POS terminals, smart locks, and kiosks for flexibility.
    • Long Cables (300+ mm): Used in industrial applications, often requiring shielding to prevent signal loss.

    Where Is the NFC Antenna on My Phone?

    Nowadays, most smartphones have the NFC antenna integrated into the mainboard, it is always located on the back panel, usually near the top or center. In this way, we can ensure the optimal contactless transactions with payment terminals and other NFC devices. If you want to locate the NFC antenna on your phone, try to use below methods:

    1. Check the phone’s manual for NFC placement details, it always show where the NFC antenna and how to use it.

    2. Look for the NFC logo on the back of the phone.

    3. Use an NFC-enabled card—move it around the back of the phone until it responds.

    What Is the Impedance of NFC Antenna PCB?

    The impedance of an NFC antenna PCB typically ranges between 50ohm and 200ohm, with 50ohm being the most common standard. Since NFC operates at 13.56 MHz, impedance matching ensures that the maximum amount of power is transmitted between the antenna and the NFC controller. Poor impedance matching can lead to signal reflection, power loss, and reduced communication range. Factors affecting NFC antenna PCB impedance including:

    • Antenna size and shape: The number of turns and the loop configuration affect inductance and resistance.
    • Substrate material: Different PCB materials have varying dielectric constants, impacting impedance.
    • Trace width and spacing: Wider traces lower resistance, while spacing affects mutual inductance.
    • Environmental factors: Nearby metals and circuit components can alter the effective impedance.

    How Do I Check My Antenna Impedance?

    To measure NFC antenna PCB impedance, use specialized RF measurement tools such as a Vector Network Analyzer (VNA) or an impedance bridge. Let’s take VNA for example, here is a step-by-step process to measure antenna impedance:

    1. Connect the Antenna to a VNA: Attach the antenna’s feedline to the VNA using a coaxial cable with known impedance.

    2. Perform S11 Parameter Measurement: The S11 reflection coefficient indicates how much energy is reflected back from the antenna. A lower value (closer to 0 dB) means better impedance matching.

    3. Analyze the Smith Chart: The Smith chart helps visualize impedance variations and determine required adjustments.

    4. Use a Matching Circuit: If impedance is off, introduce capacitors or inductors to fine-tune the circuit.

    5. Verify with Load Testing: Apply an NFC reader and test real-world performance to confirm effective impedance matching.

    Alternative Methods:

    • Impedance Bridge: This measures resistance and reactance separately, providing a simple yet effective impedance estimation.
    • Oscilloscope & Signal Generator: While not as precise as a VNA, this setup can provide insights into impedance variations under different frequencies.

    NFC PCB Antenna Design Guide

    Designing an NFC PCB antenna requires careful consideration of parameters like inductance, impedance matching, material selection, and trace layout.

    Wi-Fi PCB Antenna Design Considerations

    Designing a Wi-Fi PCB antenna requires careful planning to ensure optimal performance, minimal signal interference, and reliable wireless connectivity. Here are key factors to consider:

    1. Antenna Selection and Structural Requirements

    • For optimal performance, prioritize the PIFA antenna (Planar Inverted-F Antenna) over standard chip antennas, as it offers higher success rates and better efficiency. Ensure the antenna length corresponds to a quarter of the free-space wavelength (e.g., approximately 30.6mm for 2.4GHz).
    • If using SMT chip antennas or FPC antennas, reserve the required pad size (e.g., 2×3mm) and maintain a copper-free clearance of at least 0.8mm around them. On-board PCB antennas are suitable for cost-sensitive applications, but meandered traces should be used to optimize space utilization.

    2. Layout and Routing Guidelines

    • RF traces should maintain 50Ω impedance matching, preferably using microstrip lines, and avoid vias. A continuous ground plane should be placed beneath the RF trace.
    • The antenna must be kept away from metal objects (≄15mm) to prevent interference. Avoid metal-coated enclosures or fully sealed metal structures that could block signals.
    • The RF module should be positioned close to the antenna to shorten the transmission path while keeping a safe distance from high-speed signals (e.g., Class-D amplifiers and audio circuits).

    3. Grounding and Clearance Design

    • A continuous ground plane beneath the antenna is required, ideally with a length equal to the antenna itself (e.g., 30.6mm for 2.4GHz). If space is limited, grounding through the bottom layer can be considered.
    • The antenna area must remain clear of components and other traces, with a copper-free clearance of at least 0.8mm around it.

    4. Interference Mitigation

    • Metal structures (e.g., enclosures) should be properly grounded at multiple points to prevent poor grounding, which could lead to signal reflection and reduced efficiency.
    • Differential signal traces (e.g., audio signals) should be routed as parallel and equal-length pairs and kept away from RF areas.

    5. Performance Optimization

    • Use simulation tools to fine-tune antenna parameters (e.g., height, meandered trace spacing) to ensure bandwidth and gain match Wi-Fi frequency requirements.
    • External antennas (e.g., dipole or FPC antennas) can improve gain but should be evaluated for installation space and enclosure material compatibility.
