4 Layer PCB Manufacturer, 4 Layer PCB Manufacturer India

April 18th, 2025

4 layer PCB manufacturer is a phrase you’ll come across often when dealing with multilayer circuit board designs. These boards support more complex electronics, offering better performance in smaller spaces. Whether you’re building industrial devices or consumer electronics, a reliable 4 layer PCB partner can simplify your production process. This blog explores key factors you should consider and why choosing the right manufacturer is so important.

Established in 2006, Best Technology offers comprehensive engineering consulting services, including 4 layer PCB assembly with capabilities in FR4, HDI, rigid, rigid-flex boards, and MCPCB. Best Technology delivers 4 layer PCB manufacturing services with a focus on quality and customer satisfaction to 1700 customers across 40 countries. If you have any questions about 4 layer PCB manufacturing process or 4 layer PCB cost, welcome to contact us via sales@bestpcbs.com.

4 Layer PCB Manufacturer, 4 Layer PCB Manufacturer India

What is a 4 Layer PCB?

A 4 layer PCB is a printed circuit board with four layers of copper traces stacked together. It includes two outer layers and two internal layers. These internal layers are used for power and ground planes or routing signals.

Compared to a 2-layer board, this type allows for more routing space and better EMI control. That’s why it’s preferred in applications like embedded systems, communication devices, and consumer electronics.

Thanks to the additional layers, engineers get more room for complex circuits without increasing the board size. This makes it an excellent choice for compact and high-performance designs.

4 Layer PCB Manufacturer

What is the Best Stackup for 4-Layer PCB?

Stackup matters a lot in any multilayer PCB. For 4 layer boards, the best stackup usually balances signal integrity, EMI control, and manufacturability.
The standard 4-layer PCB stackup looks like this: Top Layer – Inner Layer 1 – Inner Layer 2 – Bottom Layer. Here’s a common configuration:

  • Top Layer (Signal)
  • Inner Layer 1 (Ground)
  • Inner Layer 2 (Power)
  • Bottom Layer (Signal)

This arrangement keeps the signal layers next to the planes, which helps reduce noise and crosstalk. In some cases, designers may opt for different configurations based on signal speed or isolation needs. However, grounding between signal layers is one of the most effective ways to ensure signal stability.

How Thick is a 4-Layer PCB Core?

PCB thickness is an essential spec. In a 4-layer board, the thickness can vary depending on the prepreg and core materials used.

A typical 4-layer PCB has a thickness of 1.6mm. This includes the core and prepreg materials between layers. For instance:

  • Core thickness: around 0.8mm
  • Prepreg layers: 0.2mm each
  • Copper foil: 35”m or thicker depending on current requirements

If your design needs specific mechanical properties, you can go thicker or thinner. Many 4 layer PCB manufacturers offer customization for thickness. So, whether you’re working with handheld devices or industrial-grade equipment, there’s a solution that fits.

4 Layer PCB Manufacturing Process

The process of making a 4-layer board is more complex than single or double-layer boards. But it allows for higher performance. Here’s a quick walk-through:

Step-by-Step Overview:

Inner Layer Imaging and Etching

  • The manufacturer starts with laminates. Patterns are transferred to the inner layers using a photoresist. Then, copper is etched away to form the desired traces.

Layer Lamination

  • The etched inner layers are stacked with prepreg material and outer copper foils. This sandwich is then laminated under high heat and pressure.

Drilling

  • Holes are drilled to connect the layers, including vias that link top to bottom.

Plating

  • The drilled holes are electroplated with copper to ensure conductivity across layers.

Outer Layer Imaging and Etching

  • Similar to the inner layer, patterns are added to the outer surfaces and etched.

Solder Mask and Surface Finish

  • A protective solder mask is applied. Then, finishes like HASL, ENIG, or OSP are added to the pads for better solderability.

Silkscreen Printing and Testing

  • Component labels are printed. Finally, every board goes through electrical testing to ensure performance.

This process ensures the board meets all functional and quality standards. A professional 4 layer PCB manufacturer maintains tight control during each step to avoid issues later.

How Much Does a 4 Layer PCB Manufacturer Charge vs 6 Layer?

Pricing always plays a major role. The cost of a 4-layer board depends on materials, size, and volume. On average, a 4-layer PCB may cost 25%–50% less than a 6-layer PCB of the same dimensions. Here’s why:

  • Material use: Fewer layers mean less copper and prepreg.
  • Processing time: Less time required for pressing and drilling.
  • Testing cost: 6-layer boards need more in-depth electrical testing.

For basic 4-layer boards, pricing can start at $50–$100 per square meter for large batches. Complex designs or special materials may push it higher. That said, when you’re scaling production, the per-unit cost drops quickly.

DOB LED vs. COB LED​ vs. SMD LED: 3 Options for LED PCB

April 17th, 2025

DOB Full Form in LED

DOB full form in LED is “Driver on Board.” In LED lighting, this means the driver circuit is built directly onto the LED board. There’s no need for a separate external driver. This configuration is based on the consideration that LED drivers have been dominantly designed as switching mode power supplies.

A DOB LED PCB is a neat package. It has the LEDs, power regulation circuit, and other supporting components all mounted on a single board. This includes rectifiers, surge protectors, constant current regulators, and sometimes capacitors to stabilize the current.

Because the dob led driver circuit is built-in, these boards are usually smaller and more lightweight. Most use aluminum base PCBs, which help draw heat away from the components to improve lifespan.

DOB LED vs. COB LED​ vs. SMD LED: 3 Options for LED PCB Board

What Is LED Driver?

Simply put, a LED driver is a part that mainly used to control the power going to your LEDs. LEDs work best when they get a consistent current. A driver makes sure the current stays steady, even when the input voltage changes.

Traditional LED lighting uses an external driver. It converts AC (from your wall) to DC (what the LEDs need). But in the LED DOB approach, this conversion happens right on the board. That’s why DOB lights don’t need external drivers.

However, some large-scale lighting systems still prefer external drivers for better thermal control and longer lifespan. For smaller applications, dob led lights are a good choice due to the convenience.

LED Bulb DOB Circuit Diagram​

A basic led bulb dob circuit diagram includes:

Input terminals (AC supply)

Bridge rectifier

Filtering capacitor

Constant current IC or regulator

LED array

Here is a typical diagram of DOB LED circuit:

LED Bulb DOB Circuit Diagram​

How Does DOB LED Driver Circuit Work?

The DOB LED driver circuit operates through several key functional blocks, including input overvoltage protection, rectification and filtering, current limiting, and PWM dimming.

1. Input Overvoltage Protection

    The DOB LED circuit includes an overvoltage protection mechanism to handle power surges caused by lightning or sudden spikes from the mains. When a DC voltage is applied across the “+48V” and “GND” terminals, current first flows through resistor R1 to limit the surge. If the voltage rises beyond a safe level, the current through R1 increases, causing a voltage drop. Once this drop exceeds 1W, the protection system activates—R1’s resistance instantly increases to an extremely high value, effectively blocking the current and shielding the +48V input line from damage.

    2. Rectification and Filtering Circuit

    When the input is AC power, a bridge rectifier converts the alternating current into direct current. This DC output passes through the rectifier for polarity protection, preventing damage from reversed connections. Components like capacitors C1 and C2, along with inductor L1, smooth out the ripples and produce a stable DC voltage.

    3. Current Limiting Circuit

    LEDs require stable current to operate efficiently and avoid damage. That’s why DOB circuits use a current-limiting mechanism, typically based on either resistors or constant current sources. A constant current driver is commonly preferred because it maintains consistent brightness across varying input voltages and temperatures, helping extend LED life and performance.

    4. PWM Dimming Control

    To control brightness, DOB LED circuits often use PWM technology. By adjusting the duty cycle of the PWM signal, the average current through the LED changes, which alters the brightness. This is usually done by modifying the voltage at the top end of the feedback resistor, which in turn regulates the current through the LED.

    DOB LED PCB Advantages and Disadvantages

    Advantages:

    • Fewer components: With no external driver, the whole assembly becomes simpler.
    • Cost-effective: Fewer parts and simpler design reduce production costs.
    • Space-saving: The integrated design is ideal for compact lighting like LED bulbs or tubes.
    • Lightweight: No bulky driver means less weight.
    • Easy to install and replace: Just plug and go. No extra wiring or enclosures.

    Disadvantages:

    • Limited in high-wattage systems: Integrated drivers can heat up quickly and struggle with larger currents.
    • Heat management is critical: Without good cooling, performance drops over time.
    • Lifespan is tied to board quality: A poorly designed dob led driver circuit may shorten LED life.
    • Not suitable for dimming: Most DOB circuits don’t support dimming out-of-the-box.

    Despite the challenges, dob led lights work well in most indoor environments. They offer an easy plug-in lighting solution without the need for complex wiring.

    LED Bulb DOB

    What Is DOB LED Used For?

    So, where do you use a dob led? Pretty much everywhere light is needed in a simple, cost-effective form. You’ll find dob led pcbs in:

    • LED light bulbs
    • Tube lights
    • Panel lights
    • Garden lights
    • Wall lamps
    • Street lamps (low wattage)

    Because the entire system is compact, manufacturers often choose DOB for plug-and-play lighting. A dob led light is cheaper to make and easier to sell in volume. The efficiency and simplicity make DOB ideal for home lighting, budget projects, and commercial interiors.

    What Is COB LED PCB?

    COB, which stands for “Chip on Board.” In this case, multiple LED chips are mounted directly onto the PCB with very little space between them. This setup creates a dense, bright light source. The PCB itself is usually aluminum-based. The close grouping of chips gives the COB LED PCB its signature even, shadow-free glow. COBs are used in spotlights, floodlights, and other high-intensity applications.

    Unlike dob led, a COB PCB doesn’t have a driver built-in. It needs an external LED driver to control current and voltage.

    What Is COB LED PCB?

    Features of COB LED PCB

    • High density of LEDs on one board
    • Excellent brightness and high lumen output
    • Smooth and even light beam
    • Strong thermal management (especially with aluminum core PCBs)
    • Compact design for high-power fixtures

    COB designs work well in lighting products where powerful and uniform light is needed.

    What Is COB LED PCB?

    COB LED PCB Advantages and Disadvantages

    Advantages:

    • Brighter output: More chips in one place = more light.
    • Compact but powerful: Ideal for high-performance lighting in small sizes.
    • Low glare: Even distribution of light reduces harsh spots.
    • Thermal efficiency: Designed for good heat dissipation.

    Disadvantages:

    • Needs an external driver: That adds cost and space requirements.
    • Not flexible: Fixed shape and size limit design options.
    • Slightly higher cost: More complex manufacturing process.

    Still, for strong lighting needs—like industrial or architectural setups—COB wins over dob led in brightness and beam quality.

    What Is SMD LED PCB?

    SMD stands for Surface Mounted Device. These are individual LED chips mounted directly onto the surface of the board. Unlike COB, where chips blend into one source, SMDs remain separated.

    Common package sizes of SMD LED include 3528, 2835, and 5050 SMD chips. Each number relates to the dimensions in millimeters. These chips are popular for flexible LED strips, signage, and backlit displays.

    A smd led pcb often supports RGB functions. That means each LED can emit different colors, which is useful for digital billboards, decorative lights, and custom control systems.

    What Is SMD LED PCB?

    Features of SMD LED PCB

    • High flexibility in design layout
    • Small and lightweight LEDs
    • Available in different color options (RGB & RGBW)
    • Can be used on both rigid and flexible boards
    • Suitable for decorative and general-purpose lighting

    SMD LED PCB Advantages and Disadvantages

    Advantages:

    • Design freedom: Great for custom layouts and creative shapes.
    • RGB ready: Many SMDs support multi-color output.
    • Lower cost: Ideal for mass production.
    • Good performance: Bright, efficient, and adaptable.

    Disadvantages:

    • Less heat-resistant: Not as efficient as COB in thermal handling.
    • May require more circuitry: For full color and control, extra components are needed.
    • Light is more scattered: Doesn’t provide a focused beam like COB.

    PCB Aluminium Substrate, Aluminum PCB Board for LED

    April 17th, 2025

    When it comes to reliable and advanced PCB solutions, Best Technology leads the way. With more than 18 years in the industry, we provide custom circuit board manufacturing for global clients. From prototype to volume production, we help you build better products with very good heat dissipation and military-grade quality. Our strength lies in metal-based PCBs, especially pcb aluminium substrates. These are widely used in LED, automotive, telecom, and power industries. With precision equipment and a strict quality system, we ensure high-performance boards that meet your needs.

    What Is a PCB Aluminium Substrate?

    A PCB aluminium substrate is a type of metal-based printed circuit board. (MCPCB) It uses aluminum as its base material instead of traditional FR4. This base supports layers of dielectric, and copper circuits. Aluminum PCBs offer strong heat dissipation and structural support compared with normal rigid PCB. The aluminum base acts as a heat sink. This makes the substrate ideal for high-power or thermally sensitive applications. In simple terms, it’s a PCB built on aluminum rather than fiberglass.

    Performance of Aluminium Substrate PCB in LED

    Aluminum substrate PCBs are the backbone of today’s LED lighting systems. Their ability to manage heat is the most critical factor. When LEDs operate, they generate a lot of heat at the junction point. If that heat isn’t removed quickly, the LED’s brightness fades, and its lifespan shortens. Using an aluminum board for LED, we can get these benefits:

    • Efficient heat dissipation: The aluminum metal base acts as a built-in heat sink, pulling heat away from the LED source and spreading it across the board.
    • Improved reliability: By reducing thermal stress, the board helps extend the lifespan of each LED component. That means longer-lasting light and less need for replacement.
    • Stable light output: Overheating causes LEDs to dim. Aluminum PCBs maintain the thermal balance so that brightness stays consistent. Whether it’s a street lamp or a small indoor fixture, aluminum PCBs deliver stable operation.
    • Compact design: Since aluminum boards manage heat on their own, there’s no need for bulky external cooling systems.
    • Cost-effective: Although slightly more expensive than FR4, their longer lifespan and lower maintenance needs make them a better investment for lighting manufacturers.

    6061 vs. 5052 vs. 1060 Aluminum Substrate

    In the aluminum PCB manufacturing, the common aluminium substrates that manufacturers always use are 6061 aluminum substrate, 5052 aluminum substrate and 1060 substrate. All of them are aluminum allay, but the compositions and purity are different, so that the performance different too.

    5052 aluminum sheet belongs to Al-Mg alloy, the main alloying element is magnesium, which has a content of 2.2% ~ 2.8%. In addition, it also contains a small amount of chromium (0.15%-0.35%) and other elements. The addition of which is intended to improve the strength and corrosion resistance of the alloy. 6061 aluminum sheet is Al-Mg-Si alloy, in addition to magnesium (0.8%-1.2%) and silicon (0.4%-0.8%) as the main alloying elements, copper (0.15%-0.4%) and zinc (less than 0.25%) are also added. 1060 aluminum material belongs to pure aluminum sheet, with an aluminum content of more than 99.6%, and almost no other alloying elements. Different alloy components form the basis of the different performances of these aluminum substrates. Below is a table comparison show the differences between each of them:

    Property6061 Aluminum5052 Aluminum1060 Aluminum
    CompositionMagnesium & silicon alloyMagnesium alloyPure aluminum (≄99.6%)
    Thermal ConductivityModerate (150 W/m·K)High (160 W/m·K)Very high (≈237 W/m·K)
    Strength of Extension290MPa215MPaLow
    Hardness95HB65HB30HB
    Elongation10-18%12-25%5%
    FormabilityLowHighHigh
    Corrosion ResistanceGoodExcellentGood
    Common UsesStructural parts, high-load PCBsLED lights, flexible designsHigh heat-dissipation PCBs
    CostHigherMediumLower
    (6061 vs. 5052 vs. 1060 Aluminum Substrate)

    So how to choose the suitable substrate for your aluminum PCB board? Follow this rule:

    • Choose 1060 if your project needs maximum thermal conductivity.
    • Choose 5052 if flexibility and corrosion resistance are more important.
    • Choose 6061 if you need strength and rigidity for heavy-duty PCBs.

    What Is the Dielectric Layer of Aluminum PCB?

    Aluminum substrate is generally composed of three layers: circuit layer (copper foil), dielectric layer and metal base. The dielectric layer is located between the circuit layer and the metal base layer, which acts as insulation and heat conduction. It is a polymer filled with high thermal conductivity and high insulation ceramic powder, make it is an ideal material with non-conductive but heat-conductive.

    single sided PCB aluminium substrate structure

    This dielectric layer has good heat conduction properties (thermal conductivity up to 3.0W/m-K), it is the key to thermal performance. It allows heat to pass from the copper to the aluminum while keeping them electrically isolated. The dielectric must have low thermal resistance and high breakdown voltage. Materials used often include ceramic-filled epoxy or polyimide. These support thermal conductivity while maintaining safety.

    What Is the Difference Between FR4 and Aluminum PCB?

    FR4 PCBs use fiberglass as a base. They are cheaper and more common. But they are poor at dissipating heat. They also deform more under thermal stress. Aluminum PCBs, on the other hand, handle heat much better. The aluminum pcb thermal conductivity is usually between 1.0 to 3.0 W/m·K. In contrast, FR4 is less than 0.3 W/m·K. That means aluminum PCBs can move heat away much faster. Here we listing the main differences between two of them:

    FeatureFR4 PCBAluminum PCB
    Base MaterialFiberglass-reinforced epoxyAluminum metal
    Thermal Conductivity≈0.3 W/m·K1–3 W/m·K
    Heat DissipationPoorExcellent

    WeightMuch lighterHeavier but lighter than copper pcb
    Environment ToleranceLower heat resistanceWithstands high temperatures

    How Do You Make Aluminium PCB?

    The manufacturing process of aluminum PCB is almost the same as normal FR4 PCB, except the lamination process of dielectric layer, aluminum and copper. This also is the biggest manufacturing difficult that faced by manufacturers, especially for multi-layer aluminum PCB. For the single & double sided aluminum PCB, the aluminum substrate we purchased from the manufacturers are laminated with dielectric, so we do not need to laminate again. In addition to this, the manufacturing process of aluminum PCB with insulated hole and without insulated hole are different.

    • Single-sided Aluminum PCB without insulated hole:

    Cutting raw material (substrate laminated with dielectric layer) — Circuit layer generation (D-E-S) — Solder Mask – Silkscreen — Surface Treatment — Stripping — Drill Holes — Outline (V-cut – Routing – Die Punching) — QC — Package & Delivery

    Single-sided Aluminum PCB without insulated hole
    • Single-sided Aluminum PCB with insulated hole:

    Cutting raw material (substrate without laminated with dielectric layer) — Drill larger holes — Filled resin with holes — Lamination (dielectric layer + copper + aluminum base) — Circuit layer generation (D-E-S) — Solder Mask – Silkscreen — Surface Treatment — Stripping — Drill Holes — Outline (V-cut – Routing – Die Punching) — QC — Package & Delivery

    Single-sided Aluminum PCB with insulated hole

    Manufacturing Difficulties of Aluminum PCBs

    Working with aluminum is not the same as working with FR4. It brings challenges, especially for a professional aluminum PCB manufacturer.

    1. Mechanical Processing

    Drilling holes on aluminum PCBs is possible, but the inner walls and board edges must be completely free of burrs. Even a slight burr can cause the board to fail the high-voltage test. Milling the outline is also quite difficult. The milling cutter used for FR4 PCB board has a relatively low hardness, while the milling cutter used for aluminum substrate has a high hardness. During the processing, the milling cutter for fiberglass board production has a high speed, while the milling cutter for aluminum substrate production has a speed at least 2/3 slower. As an alternative, punching with high-precision dies is often used—but die making requires exceptional skill, making this one of the main challenges in aluminum PCB manufacturing.

    After punching, the edges must be clean and smooth, without any burrs or damage to the solder mask along the edges. Most factories use compound dies. Holes are punched from the circuit side, and the outline is punched from the aluminum side. This requires specific techniques, such as upward shearing and downward pulling during punching. Even after punching, the board’s warpage must be strictly controlled and should remain under 0.5%.

    2. Protecting the Aluminum Surface During Processing

    The aluminum base must remain completely free of scratches throughout the entire production process. Any direct contact with hands or chemicals can cause surface discoloration or oxidation, which are absolutely unacceptable. In many cases, re-polishing the aluminum surface is not allowed by customers. So, avoiding even the slightest damage to the aluminum layer is another major difficulty in the production process.

    Some manufacturers use surface passivation treatments, while others apply protective films before and after hot air solder leveling (HASL). There are countless tricks and methods used to keep the surface clean—every factory has its own unique way of doing it.

    3. High-Voltage Testing Requirements

    For telecom power supply boards, 100% high-voltage testing is often mandatory. Some clients require DC testing, while others specify AC, typically at 1500V or 1600V for durations of 5 to 10 seconds. Every single board must pass this test.

    Even the smallest contamination on the surface, burrs on holes or edges, jagged traces, or damage to the insulation layer can lead to arcing, leakage, or dielectric breakdown during testing. Boards that show signs of delamination or bubbling during the test are automatically rejected.

    Despite these, trusted manufacturers like Best Technology handle it well. Our experience helps solve such problems early in the process.

    How Much Does Aluminum PCB Cost?

    Many factors influence the pcb aluminium substrate price. These include:

    • Aluminum grade (6061, 5052, or 1060)
    • Thickness of copper and base layer
    • Board size and layer count
    • Surface finish type
    • Quantity ordered
    • Special design features (e.g., thermal vias, contours)

    In general, aluminum PCBs cost more than FR4 boards. But for heat-sensitive designs, the added cost pays off in reliability.

    For instance, a basic one-layer aluminum PCB may start from $1.0–$5.0 per unit in bulk. Complex designs with multi-layers or special finishes can go higher. Best Technology offer competitive pricing without cutting corners. We also provide quick prototypes aluminium PCB substrate and full-scale production to meet your timeline and budget.

    PCB Boards Manufacturing, PCB Board Manufacturing Process

    How Are PCB Boards Made?

    The PCB board manufacturing process starts with a design. Engineers use software to draw the layout. Then, the manufacturer prints the layout onto copper-coated boards. The next steps include etching away the extra copper and drilling holes for components. After that, they add protective layers, silkscreen labels, and surface finishes.

    Here’s a simple breakdown:

    • Design and layout
    • Photolithography (imaging the layout)
    • Etching copper
    • Drilling holes
    • Plating (hole metallization)
    • Solder mask application
    • Silkscreen printing
    • Surface finishing
    • Testing and quality checks

    Each step must be done with high precision. Even a small mistake can lead to failure in the final device. Reliable circuit boards manufacturing always includes strict testing before delivery.

    How Do PCB Boards Work?

    PCB boards are like the nervous system of a machine. They connect different components using copper tracks. Signals and power travel along these paths to make everything function. For example, in a phone, the PCB connects the battery, screen, and processor.

    Without a PCB, the electronic parts would be hard to organize. The board keeps everything in place and allows current to move smoothly. Many layers are used in complex devices, with signals traveling through different paths. That’s why the design must be perfect.

    How Do You Clean a PCB Board in Manufacturing?

    Clean boards lead to better performance. In PCB board manufacturing, cleaning is essential. During the process, dust, oil, and metal particles can collect. So, before assembly, cleaning is done using machines and solutions.

    Most manufacturers use deionized water or alcohol-based cleaners. These help remove any leftover chemicals or particles. Ultrasonic cleaning is also common, using high-frequency waves to shake off dirt. This keeps the board reliable and free from short circuits.

    PCB Boards Manufacturing

    What is Tenting on PCB Boards Manufacturing?

    Tenting means covering vias (small holes) with solder mask. This is done for protection. It prevents dirt and moisture from entering the holes. In high-quality PCB manufacturing, tenting also improves looks by hiding the copper pads.

    There are two types of tenting:

    • Full tenting: The via is completely covered.
    • Partial tenting: Some part of the via remains open.

    Tenting is common in compact designs where protection and space-saving are important. It’s a small detail, but it helps a lot in product quality.

    Do PCB Manufacturers Install Files on Your Board?

    Yes, but with limits. Most PCB board assembly manufacturers only place the components. They follow files like Gerber, BOM (Bill of Materials), and pick-and-place. These tell them what to mount and where.

    If you need software installation or firmware upload, it must be discussed early. Some manufacturers offer this service, but not all. Always ask before placing an order. It helps avoid confusion later.

    How Long It Takes to Get PCB Board from Manufacturing?

    The lead time depends on the order. Standard production usually takes 5 to 7 days. If it’s a complex board or a large batch, it may take up to 2 weeks. Some companies offer express services. These can deliver boards in 24 to 72 hours.

    Here’s a lead time in Best Technology for FR4 prototypes for your reference, with a standard specification, of less than 1 sq meter.
