Latest Patents

One of Hashimoto's latest patents involves the creation of a copper-clad laminate. This laminate is prepared by laminating a copper foil on one side or both sides of a polyimide film through thermocompression bonding. The innovation lies in the remarkable improvement in flexibility achieved by using a polyimide film with a thickness of 5 to 20 micrometers and a copper foil with a thickness of 1 to 18 micrometers. Another significant patent is for an adhesion-enhanced polyimide film, which includes a core layer made of a polyimide with high rigidity and a low linear expansion coefficient. This film features a thin layer formed by heating a coated layer that includes a heat-resistant surface treatment agent and a polyimide precursor, resulting in a highly heat-resistant amorphous polyimide.
