What's High-speed PCB?

High-speed PCB design is a specialized area of electronics engineering that focuses on managing fast digital signals. The core of design deals with the complexities of high-frequency signals. Unlike standard PCB design, which mainly concerns connecting components, high-speed PCB design ensures that these connections support rapid signal transmission without degradation.

How to choose PCB material for high speed design?

• Low loss,CAF / heat resistance and mechanical toughness (adhesion) (good reliability)
  

• Stable Dk/ DF parameters (small variation coefficient with frequency and environment)
  
• Small tolerance of material thickness and glue content (good impedance control)
  
• Low copper foil surface roughness (reduce loss)
  
• Choose glass fiber cloth with flat windows (reduce skew and loss)
  

What are the materials used for your high-speed PCB?

Usually FR4. The PCB board we usually refer to is the substrate. It is actually composed of copper foil and prepreg, and there are many classifications of copper foil and prepreg according to different applications.

FR4 uses epoxy resin or modified epoxy resin as the adhesive, and glass fiber cloth as a reinforcing material. As long as the material of this system is used, it can be called FR4, so FR4 is the general term for this resin system. The printed circuit board using FR4 material is currently the largest and most widely used type of printed circuit board in the world.

Applications

High-speed PCBs are common in almost every industry that we interact with in our daily lives, from the bank on the corner to the device and infrastructure you’re using to read this article — and that goes double for anyone reading this on a mobile device.

Some of the applications and industries we’ve worked with on high-speed digital PCBs include:

• Network communications for signal integrity verification
  

• Small-factor layout and design for elements such as radios with a high need for impedance control
  
• Consumer-facing installed electronics, such as ATMs, which need to be maintained with the latest standards, have high volumes and need a short time-to-market
  
• High-speed digital test boards for various signals, including tests for RF signal roll-off
  
• Medical equipment that requires high-speed, extremely dense but low-cost individual PCBs
