ABSTRACT:
A specialized desoldering iron utilizes a blade which takes the form of a quadrilateral enclosure having a pair of heating elements mounted to two opposite walls of the enclosure. The enclosure is shaped and dimensioned to fit over a quad flat pack integrated circuit such that the lower edges of the walls of the enclosure come down onto the soldered leads of the integrated circuit. The two heating elements provide enough heat to simultaneously desolder all of the leads of a large quad flat pack, and the enclosure is open-topped so that the large heat sinks which are mounted atop IC's that consume a high level of power do not interfere with the desoldering process.
