Abstract:
1. An integrated circuit (IC) package, comprising: a surface of said IC having a plurality of contact leads disposed thereon, wherein the plurality of contact leads comprises solder balls affixed to the surface of the IC package; and a plurality of contact pads disposed on the surface of the IC package, wherein the plurality of contact pads is adjacent to the plurality of contact leads, wherein the plurality of contact pads comprises a substantially flat outer surface extending from the surface of the IC package, wherein the outer surface of each contact pad of the plurality of contact pads extends from the surface of the IC package by a first elevation and a surface of each of the solder balls of the plurality of contact leads extends from the surface of the IC package by a second elevation; a socket body having a plurality of test pins, wherein a first portion of the plurality of test pins is configured to contact the plurality of contact pads when engaged with the IC package and a second portion of the plurality of test pins is configured to contact the plurality of contact leads when engaged with the IC package, wherein each test pin of the first portion of the plurality of test pins and each test pin of the second portion of the plurality of test pins are adjustable in height to accommodate the first elevation and the second elevation, respectively, when engaged with the IC package, and wherein a first portion of the plurality of contact leads forming a first ring of contact leads is arranged in an inner perimeter area of the surface of the IC package, the first ring of contact leads is exclusive of any contact pads, and a first portion of the plurality of contact pads forming a first ring of contact pads along an outermost perimeter area and the first ring of contact pads is exclusive of any contact leads, and wherein the first ring of contact pads is arranged adjacent to the first ring of contact leads, wherein at least a second portion of the plurality of contact leads forming a second ring of contact leads is arranged adjacent to first ring of contact pads on the surface of the IC package, the second ring of contact leads exclusive of any contact pads, wherein at least a third portion of the plurality of contact leads is arranged in a grid pattern on the surface of the IC package and is located in a center area of the surface of the IC package, wherein at least a second portion of the plurality of contact pads forming a second ring of contact pads is arranged between the second ring of contact leads and the third portion of the plurality of contact leads on the surface of the IC package.
