Classification of hard and soft printed circuit board
- Dec 31, 2016 -

Divided into rigid circuit boards and flexible circuit boards, rigid-Flex boards. General PCB shown in the first picture below is known as rigid (Rigid), PCB, in the second picture the yellow connector is called flexible (or interference Flexible) PCB. Rigid PCB and flexible PCB visual difference is the flexible PCB can be bent. Rigid PCB thickness of the common 0.2mm,0.4mm,0.6mm,0.8mm,1.0mm,1.2mm,1.6mm,2.0mm. Common thickness of 0.2mm for flexible PCB and welding parts in place plus the thickening layer behind it, thickening layer of thickness 0.2mm, 0.4mm. Understand the purpose of these is to structure designed to provide a spatial reference for them. Rigid PCB materials commonly include: paper phenolic laminates, epoxy resin paper laminates, glass mat of polyester laminates, epoxy glass cloth laminated sheet; common flexible PCB material includes: polyester films, polyimide films, FEP film.

Raw materials

CCL is the production of printed circuit board substrate material. It as supporting a variety of components, and to achieve the electrical connection or electrical insulation between them.

Aluminum plate

PCB aluminum plate (the metal base plate contains aluminum plate, copper plate, iron) is a high Al-Mg-Si of alloys, low alloy plate (structures, see below), it has good thermal conductivity and electrical insulation properties and machining performance is now mainstream aluminum plate fusilaite.
