What is PCB?
A printed circuit board (PCB)mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Components are generally soldered on the PCB.-
Printed circuit boards are used in all but the simplest electronic products. They are also used in some electrical products, such as passive switch boxes.
The base pcb material (CCL-Copper Clad Laminate) is a composite material that composed of dielectric layer (Resin, glass fiber) and high-purity conductor (copper foil).

PCB material classification:
1, classification according to reinforced materials (the most commonly way)
a. Paper board(FR-1, FR-2, FR-3)
b. Epoxy Glass Cloth (FR-4, FR-5)
c. Composite board (CEM-1, CEM-3)
d. HDI board (RCC-Resin Coated Coppe)
e. Special board (metal board, ceramic board, etc.)
2, classification according to the different types of resin
a. Epoxy resin
b. Polyester resin
c. PI resin (polyimide)
3, classification according to flame retardant properties
a. Flame retardant (UL94-VO, UL94-V1)
b. Non-flame retardant (UL94-HB level)
