  • LOW GLOSS BLACK POLYIMIDE FILM COMPRISING A STRESS CANCELING RESIN LAYER AND A METHOD FOR PRODUCING THE SAME
    Publication number: 20200062995
    Abstract: Disclosed is a low gloss black polyimide film produced from a soluble black polyimide resin composition capable of realizing matte by surface transfer of a support film, without addition of a matting agent. Also provided is a black polyimide film including a stress canceling resin layer and having no curl or distortion. The black polyimide film includes: a stress canceling resin layer; a support film; and a black polyimide resin layer coated on the support film in a flexible manner, wherein low gloss is realized without addition of a matting agent, and the stress canceling resin layer for residual stress cancellation of the black polyimide resin layer is provided on the other surface of the support film.

  • Rigid flexible printed circuit board and method of fabricating same
    Patent number: 7347950
    Abstract: A rigid flexible printed circuit board (PCB) and a method of fabricating the same. Since a polyimide copper clad laminate is not used during the fabrication of the rigid flexible PCB, an increase in cost resulting from use of the polyimide copper clad laminate and poor reliability of adhesion at an interface between different materials are avoided.
