A Printed Circuit Board (PCB) is a Board made of different heat resistant insulating materials. Conductive copper tracks are printed or etched onto this con-conductive base substrate. Electronic components are then soldered onto this board making it a Printed Circuit Board Assembly (PCBA).
PCB Materials can be classified according to their properties. The base material of a PCB (CCL – Copper Clad Laminate) is basically composite material made of dielectric layer (Resin, Glass Fiber) and conductor or high purity (copper foil). Let’s now understand different materials for base of Printed Circuit Board according to their properties.
PCB Materials classification according to reinforced materials (most common):
1.Paper board – FR-1, FR-2 (Phenolic Cotton Paper), FR-3 (cotton paper and epoxy)
2.Epoxy Glass Cloth – FR-4 (Woven Glass and Epoxy), FR-5 (Woven Glass and Epoxy)
3.Composite board – CEM-1 (Cotton Paper and Epoxy), CEM-3 (Non-woven Glass and Epoxy)
4.HDI board (RCC – Resin Coated Copper)
5.Special board (metal board, ceramic board, etc.)
PCB Materials classification according to types of resin:
1.Epoxy resin
2.Polyester resin
3.PI resin (polyimide)
PCB Base Material classification according to flame retardant properties:
1.Flame retardant (UL94-VO, UL94-V1)
2.Non-flame retardant (UL94-HB level)
Conclusion
Material for the base of a Printed Circuit Board is selected based on PCB design and Application. Not every PCB Material is suitable for all applications.
