Product Description

Product Description

Copper Clad Laminate, abbreviated to CCL, is a type of base material of PCBs. With glass fiber or wood pulp paper as reinforcingmaterial, a CCL is a type of product through lamination with copper clad on either one side or both sides of reinforcing materialafter being soaked in resin.According to different classification standards, CCLs can be classified into various categories:• Based on CCL mechanical rigidity, we have rigid CCL(FR-4, CEM-1, etc.) and flex CCL. Rigid PCBs depend on rigid CCLs whileflex PCBs are on flex CCLs (flex-rigid PCBs are on both rigid CCLs and flex CCLs).• Based on insulation material and structures, we have organic resin CCL (FR-4, CEM-3, etc.), metal-base CCL, ceramic-base CCL etc.• Based on CCL thickness, we have standard thickness CCL and thin CCL. The former one requires at least 0.5mm thickness whilethe latter can be thinner than 0.5mm. Copper foil thickness is excluded from CCL thickness.• Based on reinforcing material types, we have glass fiber cloth base CCL (FR-4, FR-5), paper base CCL (XPC), compound CCL(CEM-1, CEM-3).• Based on applied insulation resin, we have epoxy resin CCL (FR-4, CEM-3) and Phenolic CCL (FR-1, XPC).

fr4 copper clad,use glass fiber cloth as substrate material, immersed with epoxy resin, bake into prepreg sheet, combined several prepreg sheets single side or double sides with copper foil, hot pressing, curing, then forming CCL.
