Nowadays, technology is more and more developed, pcb application more and more widely, the printed circuit board can support almost all of the electronic equipment, printed circuit board is the highest share of products in the world's electronic components market. At present, Japan, mainland China, Taiwan China, Western Europe and the United States as the main printed circuit board manufacturing base. Pcb structure is more and more complex, in order to apply a variety of equipment. We are china Pcb design company, Circuit board manufacturing is complex, this article mainly describes the pcb can be divided into rigid circuit boards, flexible circuit boards and hard and soft combination board.

Generally the following figure shows the PCB as Rigid PCB, the second picture of the yellow cable is called Flexible PCB. The intuitive difference between rigid PCB and flexible PCB is that flexible PCBs can be bent. The common thickness of the rigid PCB is 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm and so on. Flexible PCB common thickness of 0.2mm, to weld parts of the place will be in the back with thicker layer, thicker layer thickness 0.2mm, 0.4mm range. Rigid PCB materials include: phenolic paper laminates, epoxy paper laminates, polyester glass felt laminates, epoxy glass cloth laminates; flexible PCB materials commonly include: polyester film, poly Amine film, fluorinated ethylene propylene film.
