ABSTRACT:
A toll for melting solder on the contacts of a surface mounted electronic component and on the corresponding contacts of a printed circuit substrate to which it is to be soldered or from which it is to be de-soldered. The tool includes a conduit for conducting hot gas to the contacts. A diverter located in the interior of the conduit deflects hot gas away from the top of the surface mounted component and confines the hot gas to the periphery of the component.
