Abstract:
A manufacturing method to form a spiral contactor in which a plurality of spiral probe is aligned to make an electrical connection with a semiconductor device or electronic parts having solder balls on the surface of printed wiring board, comprising:a step of establishing holes on an insulating substrate to form a metallic membrane on the whole surface of said insulating substrate, a step of filling an elastic elastomer in said hole to remove concave and convex portion of elastomer by a surface processing a step of forming a metallic membrane to at least a portion of said holes where elastomer is exposed, a step of forming a spiral probe-shaped membrane by etching a surface of an insulating substrate in which said metallic membrane is formed, and forming a circular membrane by etching to bellow surface, a step of forming a spiral probe by etching a surface of said insulating substrate, a step of forming a different kind of a metallic membrane on the surface of said insulating substrate, a step of forming a resist membrane on the surface of said insulating substrate to form a guide frame by a cover lay processing.
