Flexible PCB is divided into rigid circuit board and flexible circuit board, soft and hard board. Generally, the PCB shown in the following first picture is called PCB (Rigid) PCB, and the yellow line in the second Tutu is called flexible (or disturbed Flexible). The intuitive distinction between rigid PCB and flexible PCB is that flexible PCB can be bent. The common thicknesses of rigid PCB are 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm and so on. The common thickness of flexible PCB is 0.2mm. The part to be welded will be thickened at the back, and the thickness of the thickening layer is 0.2mm and 0.4mm. The purpose of understanding these is to provide them with a spatial reference for structural designer design. Including the common rigid PCB material: paper phenolic epoxy laminate, laminate paper, polyester glass mat laminate, epoxy glass cloth laminate; including common flexible PCB material: polyester film, polyimide film, FEP film.
