It 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, called copper-clad laminate(CCL) .It is used for production of printed circuit board(PCB).

Aluminum copper clad laminate has excellent flame retardant, high mechanical strength, dimensional stability etc. Especially it has very good heat sink, electromagnetic shielding and solder float.

Epoxy glass fiber sheet is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. hese attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications.

FR-1 copper clad laminated sheet/CCL consist of bleached wood pulp paper, impregnated with flame retardant phenolic-epoxy resin and clad with electrolytic copper foil.It has high electrical stability, good flame retardancy, good dimension stability and smoothness, good punching ability and widely used for Hi-Fi acoustic devices, color TV sets and other electronic appliances.
