PCB board are: cardboard, resin board, metal substrate (aluminum plate), copper foil, ceramic substrate
PCB substrate classification:
1, according to the different materials (the most commonly used classification method)
? paper substrate (FR-1, FR-2, FR-3)
? Epoxy fiberglass substrate (FR-4, FR-5)
? Composite Substrate (CEM-1, CEM-3) ?
HDI Sheet (RCC) ?
Special substrates (metal substrates, ceramic substrates, thermoplastic substrates, etc.)
2, depending on the resin
Phenolic resin plate
? epoxy board
? polyester resin board
? BT resin plate
? PI resin plate
3, according to flame retardant performance to points
? flame retardant (UL94-VO, UL94-V1)
? non-flame retardant (UL94-HB grade)
