RF board, or Radio Frequency Printed Circuit Board, is engineered for circuits operating at high frequencies where signal integrity becomes highly sensitive to material properties. Typical RF designs work in the range of 300 MHz to 3 GHz, and many advanced systems extend far beyond this.
At these frequencies, standard FR4 materials often fail to maintain stable dielectric performance and low signal loss. As a result, specialized high frequency laminates are required. RF PCBs are therefore built using materials with low dielectric loss (Df) and stable dielectric constant (Dk) to ensure consistent signal transmission.
RF board is ideal for applications with higher operating frequency requirements. Right now, we normally use following material:
These boards are widely used in applications such as:
Wireless communication systems
RF antennas and modules
Automotive radar (ADAS)
Satellite and aerospace electronics
Microwave devices
IoT and high-speed signal systems
Why Use RF PCB Instead of Standard FR4?
FR4 is cost-effective and widely used, but its dielectric properties vary significantly at high frequencies. This leads to signal loss, impedance instability, and reduced system reliability in RF designs.
More stable dielectric constant across frequency range
Better impedance control
Reduced signal distortion
Improved phase consistency
What Materials Are Used in RF PCB?
Material selection is the core of RF PCB performance. Different applications require different dielectric properties and processing characteristics.

What Is High Tg PCB?
Tg stands for Glass Transition Temperature. It is the temperature at which the PCB base material changes from a hard, glass-like state to a softer, rubber-like state. A high Tg PCB typically uses laminate materials with a Tg above 170°C, making it more suitable for thermal-intensive applications than standard FR4.
This type of PCB is widely used in products where heat is part of the design challenge, not just an occasional condition. That includes automotive electronics, industrial systems, LED modules, power conversion devices, telecom equipment, and other assemblies exposed to repeated or continuous thermal stress.
Why Choose High Tg PCB?
When the operating temperature of a PCB rises beyond the normal range, standard FR4 may no longer provide enough stability. Once the board temperature exceeds its Tg point, the substrate begins to soften, which can increase expansion, reduce dimensional stability, and affect long-term reliability. High Tg PCB materials help reduce these risks by offering better resistance to thermal stress.
A high Tg board is commonly selected when your project requires:
Better heat resistance during operation
Improved stability during lead-free soldering
Stronger resistance to thermal cycling
Lower risk of warpage in multilayer structures
More reliable performance in demanding environments
In practical design, the Tg value of the PCB material should usually remain above the real working temperature to give the product a better reliability margin.
Standard FR4 vs High Tg FR4
Choosing between standard FR4 and high Tg FR4 depends on the actual thermal load of the product, not only on board cost.
Material Grade
Typical Tg Value
Typical Use
Standard FR4
130â140°C
General electronics
Mid Tg FR4
Around 150°C
Moderate thermal demand
High Tg FR4
Around 170°C or above
High-temperature and high-reliability designs
High Tg FR4 is often preferred when the design involves multiple lamination cycles, multilayer structures, higher soldering temperatures, stronger thermal stress during assembly, or elevated working temperatures during long-term operation.
Key Benefits of High Tg PCB
Better Thermal Stability
High Tg materials can withstand higher temperatures without softening as quickly as standard materials. This helps the board remain more stable during operation and assembly.
Lower CTE
A lower coefficient of thermal expansion helps reduce stress on copper circuits, plated holes, solder joints, and mounted components.
Improved Mechanical Strength
High Tg laminates offer better dimensional stability under thermal cycling, which is important in products exposed to repeated heating and cooling.
Enhanced Reliability
These materials are widely used in industrial, automotive, aerospace, and other harsh-environment electronics because they support more stable long-term performance.
Better Dimensional Stability
High Tg materials show smaller dimensional change under high temperature and humidity, which helps reduce manufacturing and reliability issues caused by environmental variation.
High Tg PCB Materials We Can Support
Different projects require different material systems. We can support a wide range of high Tg laminate options based on your application, stackup, and reliability target.
Tg is the temperature where the PCB material begins to soften and lose rigidity. It mainly affects mechanical behavior and dimensional stability.

What Is an Automotive Thick Copper MCPCB?
An automotive thick copper MCPCB is a heavyâcopper circuit board engineered specifically for vehicle power systems.It uses 3oz to 12oz copper layers to safely carry high current and efficiently dissipate heat. Built to withstand -40°C to +150°C, high vibration, humidity, and thermal stress, it delivers longâterm reliability. This type of PCB is essential for highâpower automotive applications where standard boards cannot perform.
Why Use Thick Copper MCPCBs in Automotive Power Modules?
Thick copper greatly reduces electrical resistance and lowers IÂČR power loss in highâcurrent circuits. Superior thermal management prevents hotspots and extends the service life of power components. High mechanical strength resists vibration and thermal stress in harsh vehicle environments.
It is widely used in EV inverters, battery management systems, on-board chargers, and highâpower distribution units.Without thick copper technology, highâpower automotive systems face overheating and reliability risks.
How Does Thick Copper Improve Thermal Performance in Vehicles?
Thick copper greatly boosts thermal performance in automotive power systems because copper is one of the most thermally conductive materials used in PCBs. Compared with standard thin-copper boards, automotive thick copper PCB quickly moves heat away from heat-generating components, preventing dangerous hotspots.
In high-power vehicle applications such as EV inverters and on-board chargers, components release large amounts of heat during operation. Thick copper layers spread this heat evenly across the entire board surface instead of trapping it in small areas. This even distribution lowers peak temperatures and stabilizes the whole module.
When combined with metal core or high-Tg substrates, thick copper forms an efficient thermal pathway that reduces overall thermal resistance dramatically. Lower thermal resistance means cooler running components, longer service life, higher reliability, and safer operation in harsh automotive environments.

Heavy Copper PCB Design Considerations
Heavy copper board design is different from standard PCB design. Thicker copper affects current capacity, thermal behavior, trace geometry, and manufacturability. A good design should balance electrical performance with production feasibility.
1. Current Carrying Requirements
The minimum conductor width and copper thickness should be based on:
Required current
Acceptable temperature rise
Board layout space
Heat dissipation conditions
Wider traces and thicker copper improve current handling, but they also affect routing density and process difficulty.
2. Copper Profile and Manufacturing Impact
Heavy copper traces may not form a perfect rectangular shape after fabrication. The final conductor profile depends on plating and etching methods. This should be considered in spacing and tolerance planning.
3. Board Thickness
Heavy copper layers can increase total PCB thickness. This may affect:
Mechanical assembly
Connector matching
Drilling process
Stack-up design
Final product dimensions
4. Preferred Fabrication Method
For many heavy copper boards, additive plating processes are preferred over subtractive etching. Additive processing offers better copper build-up control, though it usually increases fabrication cost.
5. Tolerance
Typical tolerance for conductor width, spacing, and thickness is around ±20%, although tighter control may be achievable depending on the board structure and manufacturing process.
We support heavy copper PCB manufacturing for a wide range of power and thermal applications.

An extra thin PCB is a printed circuit board made with a much thinner profile than standard FR4 boards. In most applications, conventional PCB thickness ranges from 1.0 mm to 2.0 mm. By contrast, extra thin PCBs are typically manufactured in thicknesses such as 0.30 mm, 0.25 mm, 0.20 mm, and even 0.15 mm.
These boards are often called thin PCB, ultra thin PCB, or very thin PCB. They are designed for products where space is limited, weight matters, or a slimmer structure is required for the final assembly.
As electronic devices continue to become smaller, lighter, and more portable, extra thin PCB is being used in a growing number of compact electronic products.
Why Are Extra Thin PCBs Used?
Extra thin PCBs are widely used when a design needs to reduce overall thickness without switching to a flexible circuit. In many cases, they offer a practical middle ground between standard rigid PCBs and FPCs.
Compared with regular FR4 boards, extra thin PCBs help:
save installation space
reduce product weight
support compact internal layouts
improve product portability
lower cost compared with some flexible circuit solutions
Extra thin FR4 PCB can also provide a certain degree of bendability during assembly, especially in very low thickness designs. While it is not the same as a flexible PCB, it can still be useful in products that need a slim and semi-rigid structure.
What Thickness Can Extra Thin PCB Reach?
At EBest Circuit, extra thin PCB can be produced in the following common thicknesses:
0.15 mm
0.20 mm
0.25 mm
0.30 mm
These boards can be made with or without solder mask, depending on the application requirement. Available copper thickness options include:
0.5 oz
1 oz
2 oz
3 oz
The actual structure will depend on the layer count, copper requirement, mechanical strength, and final product usage.
Extra Thin PCB vs Flexible PCB
Extra thin PCB and flexible PCB may look similar in very slim designs, but they are not the same product.
Extra thin PCB is still based on FR4 material, which keeps the board rigid or semi-rigid. Flexible PCB, on the other hand, is made from flexible substrates such as polyimide and is designed for repeated bending.
Here is the practical difference:

Typical applications include:
SIM cards
TF cards
NFC devices
mobile phone charging modules
wearable electronics
sensor cards
drawing boards
metro tokens or smart transit devices

What Makes Extra Thin PCB Manufacturing More Challenging?
Although the process flow is similar to standard FR4 PCB manufacturing, extra thin PCB requires much tighter process control.
Because the board is much thinner, it is more sensitive during fabrication. Problems such as panel deformation, handling marks, instability during transfer, and stress during drilling or plating must be controlled carefully.
For this reason, extra thin PCB production often needs:
more precise panel handling
better lamination control
careful drilling and imaging setup
optimized plating parameters
suitable support tooling during processing
controlled packing to protect flatness and surface quality
At EBest Circuit, we apply stricter production control for ultra thin boards and use appropriate equipment to ensure smooth processing throughout each manufacturing stage.
Stack-Up Options for Extra Thin PCB
The stack-up of extra thin PCB is usually simpler than standard multilayer boards because the total board thickness is highly restricted.
The board structure is still based on standard FR4 construction, but it uses thinner core and prepreg materials to achieve the required profile.
Typical 2-Layer Extra Thin PCB Structure
A 2-layer extra thin PCB usually includes:
top copper layer
thin FR4 core
bottom copper layer
optional solder mask on one or both sides
This type of structure is commonly used in card-like products and compact electronic modules.
Typical 4-Layer Extra Thin PCB Structure
A 4-layer extra thin PCB is possible, but the thickness is usually around 0.6 mm or above depending on the copper and dielectric design.
A 4-layer thin PCB stack-up generally includes:
top copper
thin prepreg/core
inner copper layers
thin prepreg/core
bottom copper
The exact construction should be reviewed based on impedance, mechanical strength, via design, and assembly method.
Why Choose FR4 Extra Thin PCB Instead of Standard PCB?
FR4 extra thin PCB is a strong choice when you need a thinner board but still want the advantages of rigid PCB processing.
It offers several benefits:
better rigidity than flexible PCB
lower material cost in many designs
easier assembly in some rigid product structures
good compatibility with standard PCB surface finishes
reliable electrical and mechanical performance for compact devices
For products that do not need repeated bending, an extra thin FR4 PCB can be a cost-effective and stable solution.
How EBest Circuit Supports Extra Thin PCB Projects?
