Abstract
Abstract A manually held universal extraction tool for removing integrated circuits from sockets. The tool as disclosed can be operated with one hand and primarily includes a plunger located within a barrel movable therewith, the barrel having a hooked member attached thereto. The barrel is movable upwardly and the amount of upward movement is controlled by an adjustment member so that the hook moved with the barrel will lift the integrated circuit from the socket, when the hook is placed in the relief formed between the integrated circuit in socket.
