Latest Patents

One of Keith's latest patents is focused on the individual selective rework of defective ball grid array (BGA) solder balls. This method involves using a single-ball extractor/placer apparatus equipped with a heatable capillary tube pickup head, which may also utilize vacuum suction. The process begins with identifying a defective solder ball, which is then extracted and disposed of. A nondefective solder ball is subsequently picked up, positioned on the vacated site, and thermally softened for attachment. The method may include applying flux to either the replacement solder ball or the vacated site. This automated extractor/placer apparatus enhances the efficiency of locating, extracting, and replacing defective balls, ensuring the completion of a fully operable BGA.
