FR4 Copper Clad Laminate 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. Usually used in PCB with printed circuit on one or both sides of computers, home electric appliances and other lines.

Advantage:

1.Higher mechanical properties, 
2.Dielectric properties. 
3.Good heat/moisture  resistance .

4.Stable electric performance in high temperature.

5.Good flatness, smooth surface,no pits
