‍Fr4 printed circuit board‍ is a kind of copper foil covered laminated board formed through heat pressing after the electric industry alkali-free glass fiber dips into thermoset epoxy resins and is covered with copper foil at one side or both sides. Copper Clad Laminate FR-4 is usually used in PCB with printed circuit on one or both sides of computers, home electric appliances and other lines.

 

Properities
1. Higher mechanical properties,
2. Dielectric properties.
3. Good heat/moisture resistance.
4. Stable electric performance in high temperature.
