Abstract:
1. A method for fabricating a proximity sensing module that is adapted to be attached to an inner surface of a housing of a mobile device, the method comprising: adhering a lower conductive film to a release sheet; patterning the lower conductive film into a lower connective pad after the adhering the lower conductive film; patterning an upper conductive film to form a patterned conductive film after the patterning the lower conductive film, the patterned conductive film including an upper connective pad that is adapted to be electrically connected to a respective contact on a circuit board of the mobile device, and an induced circuit pattern that is electrically connected to the upper connective pad, wherein the upper conductive film is formed to cover the lower connective pad, and the upper connective pad is formed at a position corresponding to the lower connective pad and while patterning the upper conductive film, the lower connective pad is patterned into a shape corresponding to an outline of the upper connective pad; adhering an adhesive sheet to the patterned conductive film, the adhesive sheet having an area capable of covering the upper connective pad and the induced circuit pattern; forming a first through hole in the adhesive sheet such that the upper connective pad is exposed from the first through hole.
