Abstract:
An apparatus for applying solder to semiconductor chips is provided that employs a plurality of apertured decals to define areas for engaging solder on a semiconductor chip. Each of the plurality of decals includes an upper, center and bottom layer having apertures present therethrough. The apparatus fills the apertures with solder. The upper and bottom layers of the apertured decals are removed to provide solder portions projecting from the center layer. The apparatus provides a station for applying an adhesive layer to the exposed surfaces of the center layer having the solder portions projecting therefrom. The apparatus includes a station for contacting the solder and adhesive to the semiconductor chip. The apparatus also includes a separating structure for detaching the portion of the center layer that is in contacting to the semiconductor chip through the solder.
