Abstract:
Ball grid assembly (BGA) bumping solder is formed on the back side of a laminate panel within a patterned temporary resist. Processes such as singulation and flip chip module assembly are conducted following BGA bumping with the temporary resist in place. The resist is removed from the back side of the singulated laminate panel prior to card assembly. Stand-off elements having relatively high melting points can be incorporated on the BGA side of the laminate panel to ensure a minimum assembly solder collapse height. Alignment assemblies are formed on the socket-facing side of an LGA module using elements having relatively high melting points and injected solder.

Claim (Index 1):
A structure comprising:\n a substrate including a front side, a back side, and electrically conductive contact pads on the back side; a patterned resist film directly contacting the back side of the substrate, the resist film including channels exposing a plurality of the contact pads; a plurality of solder bumps, each of the solder bumps being within one of the channels in the patterned resist film and electrically contacting one of the contact pads; a plurality of stand-off assemblies, each of the stand-off assemblies comprising solder and being within one of the channels of the patterned resist film, each of the stand-off assemblies having, in whole or part, a higher melting point than the melting point of the solder bumps; and a plurality of contact elements on the front side of the substrate configured for electrical connection to a chip.
