Common materials of rigid PCB include: phenolic paper laminate, epoxy paper laminate, polyester glass felt laminate, epoxy glass cloth laminate; common materials of flexible PCB include: polyester film, polyimide Amine film, fluorinated ethylene propylene film.

The common thickness of rigid PCB is 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm, etc. The common thickness of the flexible PCB is 0.2mm. The thickened layer is added behind the parts to be soldered. The thickness of the thickened layer varies from 0.2mm to 0.4mm.

Raw materials: Copper-clad laminates are the substrate materials used to make printed circuit boards. It is used to support various components, and can achieve electrical connection or electrical insulation between them.

Aluminum substrate: PCB aluminum substrate (metal-based heat dissipation plate includes aluminum substrate, copper substrate, iron substrate) is a low alloyed Al-Mg-Si series high plastic alloy plate, it has good thermal conductivity, electrical insulation performance and mechanical processing Performance, now mainstream aluminum substrate.
