Polyflon is a thermally-stabilized, polyolefin thermoplastic bonding film, which is used as a substrate material for the manufacturing of multilayer PCB boards. The polyflon molecules are inert and as a result of this it is challenging to combine them with copper foil. The material requires a unique surface finish to be compatible with the copper foil at the time of PCB manufacturing. This unique treatment is performed through chemical etching on the polyflon surface, which adds to its surface roughness. An adhesive film can also be added on the polyflon surface to improve the adhesion.
