ABSTRACT:
An extraction tool is disclosed for removing integrated-circuit blocks (IC's) from soldered placement in a circuit board. Support members of the tool position it with reference to the circuit board for proper operation. Heating elements melt the solder; and a force mechanism, including a pair of grippers, is then actuated. In a two-step motion pattern, the grippers grasp the block then withdraw it from the circuit board. An ejector then forces the block from the tool.
