ABSTRACT:
Apparatus and method is disclosed for removing an integrated circuit chip from a socket in a printed circuit board without damaging the chip or other components on the circuit board. The tool has a pair of arms slidably attached to a base. The lower ends of each arm have wedge-shaped teeth projecting inwardly toward the base. Components are provided within a cavity in the base for evenly and simultaneously moving the arms and teeth inwardly toward the base. The wedge-shaped teeth are thereby driven between the socket and chip so that the chip is forced away from the socket by the inclined upper surfaces of the teeth until the chip is disengaged from the socket. The even action of the teeth disengages the chip from the socket without bending pins of the chip or otherwise damaging the chip. Further, the tool does not rest upon or press against the circuit board as the chip is removed from the socket, so the tool removes the chip from the socket without damaging other components on the circuit board.
