Surface Pre-treatment and Metal Coating of Commercial Polyimide Studied by Surface Analytical Techniques
The influence of the chemical pre-treatment of commercial polyimide foil on the adhesion of copper deposited by electroless and electrochemical processes has been studied using SEM, XPS, EDX, and IR spectroscopy. The results show that a thin surface layer, chemically different from the pure material, is important for metal adhesion. This layer, which can be influenced by chemical etching, exhibits distinctly different features in the x-ray photoelectron spectrum.
