Abstract
Disclosed is a method and apparatus for the correction of defective solder bump arrays arranged in a plurality of cavities in a mold. In the method, a faulty solder bump is searched, identified and located (i.e., its position is determined) in an arrangement of solder bumps disposed in cavities of a mold and the faulty solder bump is subsequently replaced by a prefabricated solder bump. The apparatus for carrying out the method comprises a mold holder, a scanning and locating device for finding and locating faulty solder bumps and a repair device for replacing the faulty solder bump by a prefabricated solder bump.
