FW: The classification of PCB

Some friends were asking me how to clarify all kinds of PCB, here I displayed the classification for your ref.

One kind of classification was made through base materials, including as below,

1.Organic Materialshenolic resin,epoxide resin,Polyimide,BT/Epoxy etc. The usual materials were FR4,FR2,FR1, CEM-1,CEM-2 etc.

2.Inorganic Materials:Al, Copper-invar-copper,ceramic etc.

Some people classified as Rigid, Flex and Flex-Rigid PCB.

The other kind of classification was based on the layer of the board, including single side, double side, multi layer.

The application of PCB was large-scale, being mainly used to computer, laptop, pc, cell phone, consuer electornics, LCD, car electronics etc.

Hope below information is helpful to you.
