Description
FR-4 CCL (Copper Clad Laminate)
FR-4 Copper Clad Laminate (CCL) is a rigid, flame-retardant composite insulating material used as the foundational base for manufacturing printed circuit boards (PCBs). FR-4 glass fiber copper clad laminate is a flame-retardant, glass-reinforced epoxy composite material clad with copper foil. It serves as the primary dielectric substrate for PCBs, offering an outstanding balance of electrical insulation, mechanical strength, dimensional flatness, and cost-effectiveness.
