Abstract
A method of making a connector by applying a focused beam from a laser to a polymer matrix containing plurality of conductive fibers in parallel. The laser is applied at one end of the matrix to volatilize the matrix so as to expose the plurality of conductive fibers to provide a laser fibrillated brush-like structure to define an electrically contacting surface.
Claims24
A method for making an electronic component comprising providing a nonmetallic pultruded composite member having a plurality of small diameter conductive fibers in .a polymer matrix said plurality of fibers being oriented in said matrix in a direction substantially parallel to the axial direction of said member and being continuous from one end of said member to the other to provide a plurality of electrical point contacts at each end of said member, directing, a laser beam to one end of said member, controlling said laser beam to volatilize the polymer matrix at said one end and expose the plurality of conductive fibers to provide a laser fibrillated brush-like structure having a densely distributed filament contact wherein the terminating ends of the fibers in the brush-like structure define an electrically contacting surface.
