Adhesive on Flexible PCB
Flexible Adhesives are used to laminate flexible materials together, such as multiple flexible layers, attachment of stiffeners, heat-sinks, etc.
We can sort all the adhesives into two types: Pressure Sensitive Adhesive (PAS) and Temperature Sensitive Adhesive.
Pressure Sensitive Adhesive (PAS) can be added by hand and no special lamination process. It is used to be attachment of stiffener, or add rigid PCB on Flex PCB. PAS is sensitive to temperature and many Chemical materials. So it normally won’t be used between copper and medium.
Temperature Sensitive Adhesive needs 180 degree lamination and baking during production. It has excellent Chemical resistance and can stand high temperature.
