Process and jig for plating pin grid arrays

摘要

A receiving jig for PGAs comprises a rectangular base-plate made of a corrosion-resistant metal which has at least one hole. The lengths of the edges of the base-plate have at least the dimensions of the PGA housing. Arranged on the metal baseplate are bars parallel to the surface at equidistant spacings and the height of the bars above the baseplate is at least half the length of the pins of the PGAs. The spacing between two bars on the surface of the baseplate corresponds to twice the spacing between two adjacent rows of pins on the PGA. There should be at least enough bars present to make contact with all the pins of the PGA.
