Rigid PCB

Rigid PCB often used as a main board, cannot be bent.
Rigid PCB: PCB (Printed Circuit Board),the hard board part is the same as PCB, has a certain thickness and strength, can install electronic components and withstand a certain mechanical force.
PCB is the so-called printed circuit board, which is usually called Rigid PCB. It is a supporting body among electronic components and a very important electronic component. PCB generally uses FR4 as the base material, also called rigid board, which cannot be bent or flexed. PCBs are generally used in places that do not require bending and are relatively rigid, such as computer motherboards and mobile phone motherboards.
