Often Used As a Motherboard——Rigid PCB

PCB board can be divided into rigid pcb, flexible pcb (FPC) and rigid-flex pcb according to the hardness.

Rigid pcb is often used as a motherboard. Generally, FR4 is used as the base material, and it cannot be bent. It is generally used in some places where relatively hard strength is required, such as computer motherboards and mobile phone motherboards.
