Patent ID: 7695287

Claim:
A method for mounting an integrated circuit (IC) package on a printed circuit board (PCB), which comprises: providing a plurality of conductive balls forming a ball grid array (BOA) that are arranged in a matrix pattern on one of the IC package or PCB and a respective plurality of ball sockets arranged in a corresponding matrix pattern on the respective other PCB or IC package not having the BGA thereon, each ball socket comprising a base having a circular edge and an outer side that engages a respective IC package or PCB and an opposing inner side configured for seating a conductive ball, and including a plurality of prongs secured to and extending from the inner side of the base and configured to receive and hold the conductive ball into contact with the inner side of the base and a rim formed on the circular edge and configured to form an indentation on the base of each ball socket that seats the ball on the inner side and wherein the rim engages a surface of the PCB or IC package and said rim and indentation provide a solder fillet to aid in wicking solder and compensate for board warpage; and interconnecting together the IC package, PCB, conductive balls and ball sockets as an assembly.
