Abstract:
1. A surface mount electrical interconnect forming an interface between a first set of solder balls on a BGA device and a PCB, the electrical interconnect comprising: a socket substrate comprising a first surface, a second surface, and a plurality of openings sized and configured to receive the first set of solder balls on the BGA device; a plurality of electrically conductive contact tabs attached to the socket substrate so that contact tips on the contact tabs extend into the openings an amount that permits the solder balls of the BGA device to be inserted into the openings with no resistance; a force generally parallel with the first surface of the socket substrate laterally shifting the BGA device so the contact tips engage with the first set of solder balls near an upper radii thereof proximate a second interface of the first set of solder balls with the BGA device to electrically couple the contact tabs with the BGA device and to secure the first set of solder balls in the openings; vias electrically coupling the contact tabs to contact pads located proximate the second surface of the socket substrate; and a second set of solder balls bonded to the contact pads that electrically and mechanically couple the electrical interconnect to the PCB; and wherein the electrically conductive contact tabs are attached to and extend into the openings generally parallel with the first surface of the socket substrate.
