Coming from big PCB factories, including FR4, CEM-3, FR1, XPC, CEM-1, 22F, Alu CCL and so on.It mixed with various sizes, like 5cm up, 10cm up, 15cm up, panel size, half sheet, can select as you requested.

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.
