Abstract
A flexible circuit board device for connecting to an electronic device comprised of a flexible circuit board made from flexible resistive film, an adhesive layer formed on the flexible resistive film, electrical conductive circuits formed on the adhesive layer and cured films filling the gaps between the conductive circuits. The electrical conductive circuits are formed of conductor metal foil and a plating film covering the surface of the conductor.
Claims4
A connecting device for mechanically and electrically connecting electrode portions of an electronic device and electrode portions of a print circuit board said connecting device comprising a flexible circuit board comprising:
- a flexible resistive film;
