Solder mold plates used in packaging process and method of manufacturing solder mold plates
Abstract:
Solder mold plates and methods of manufacturing the solder mold plates are provided herein. The solder mold plates are used in controlled collapse chip connection processes. The solder mold plate includes a plurality of cavities. At least one cavity of the plurality of cavities has a different volume than another of the cavities in a particular chip set site. The method of manufacturing the solder mold plate includes determining susceptible white bump locations on a chip set. The method further includes forming lower volume cavities on the solder mold plate which coincide with the susceptible white bump locations, and forming higher volume cavities on the solder mold plate which coincide with less susceptible white bump locations.
