Patent ID: 7469457

Claim:
A method of removing an integrated circuit chip package, comprising: placing a detachment jig on a printed circuit board, the detachment jig including first and second grasping members received on a surface of the printed circuit board, the first and second grasping members being forced to advance to each other; allowing a solder bump of solid state, disposed between the printed circuit board and the integrated circuit chip package, to restrain the first and second grasping members from advancing to each other; causing the solder bump to melt so as to remove restraint to the advance of the first and second grasping member; and allowing the first and second grasping members to glide to each other on the surface of the printed circuit board into a space between the printed circuit board and the integrated circuit chip package so that inclined surfaces of the first and second grasping members serve to lift the integrated circuit chip package from the surface of the printed circuit board.
