Introduction to PCB board material categories

Choosing the appropriate board is crucial in the PCB manufacturing process. Here are some common PCB boards and their characteristics introduced： 1. **FR-4**: This is the most common type of PCB material, composed of woven glass fibers soaked in epoxy resin. It offers excellent electrical insulation and mechanical strength, making it suitable for a wide range of applications. FR-4 is known for its versatility and reliability, and it is cost-effective. 2. **Polyimide (PI)**: Used for flexible PCBs, polyimide provides exceptional performance in harsh environments and high-temperature conditions. It is dimensionally stable during thermal cycling, making it ideal for multi-layer PCB constructions. 3. **Teflon**: Known for its excellent dielectric properties and minimal […]
