Abstract
An approach is provided for laminating layers for a flexible printed circuit board. The approach includes a method and apparatus for providing a base substrate and the surface of the base substrate is treated by radiating ion beams using a gas mixture including oxygen and argon to improve adhesive strength and heat resistance. A tie layer can be formed on the based film to prevent a metal conductive layer from diffusion and to increase the adhesive strength.
