Claims6
A method of assembling a land grid array module comprising a land grid array card, land grid array socket and substrate, the method comnrising the steps of:
- (a) obtaining an alignment tool comprising a nest and guide tool, wherein the nest comprises a body having a plurality of apertures and plurality of locating portions for accurately locating the land grid array socket with respect to the nest and the guide tool comprises a planar body having a plurality of guide pins for inserting into the plurality of apertures and a plurality of cutout portions;
- (b) inserting the land grid array socket and substrate into the nest;
- (c) inserting the guide tool into the nest;
- (d) picking up the guide tool, substrate and land grid array interposer socket from the nest;
- (e) placing the guide tool, substrate and land grid array socket onto the land grid array card, wherein the land grid array card has a plurality of alignment holes and the step of placing includes aligning the guide pins of the guide tool with the alignment holes of the land grid array card;
- and
- (f) removing the guide tool.
