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.

Apparatus for use with surface mounted chip carriers, comprising: a conduit, having lateral walls, an inlet end, an outlet end, and a flared portion in which the interior cross section of said conduit increases with increasing distance from said inlet end toward said outlet end, for conducting hot gas; a diverter device within said flared portion, said diverter device having a main portion whose cross section increases with increasing distance from said inlet end toward said outlet end of said conduit; said diverter device being positioned within said flared portion to divert said flow from the central portion of said conduit and to leave a channel for gas flow surrounding said diverter within said flared portion.
