<p>An electrical interposer is provide for interface between an LGA (24) and a mother board (34). The interposer includes a spacer (60) with stepped opening (64) for each solder interconnection which prevents the relaxation of mechanical contact force while ensuring the integrity of each solder interconnection. The interposer provides nobel metal plated contact pads (66) on a first surface to receive the contact members of LGA connector and contact pads (70) for BGA solder connections for attachment to the mother board.</p> |
