The English name is (Printed Circuit Board) PCB, (Flexi ble Printed Circuit board) FPC circuit board (FPC circuit board is also called flexible circuit board. Flexible circuit board is a kind of printed circuit board made of polyimide or polyester film as the base material with high reliability and excellent flexibility.

[0003] Most of the existing circuit boards adopt an integrated structure and are fixedly installed on the casing of electronic products. When the electronic products are subjected to external impact or vibration, the circuit boards are easily damaged. The seismic design on some existing circuit boards adopts elastic parts such as springs to provide vibration reduction force to the circuit boards in the longitudinal direction. In this way, the circuit boards are very likely to shake naturally during installation and are not stable enough.
