FR4 Copper Clad Laminate sheet
Newlytrend Copper Clad Laminate FR4 (single or double sided)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
