ABSTRACT:
A solder delivery system has a continuous element of solder material adjacent to at least one polymeric layer, which is provided with window means to control the flow of solder. The layers, if there are more than one, may be separate pieces, or may be parts of a folded sheet or a tube of polymeric material. In use, the conductors to be soldered are placed adjacent to corresponding terminals of a substrate and the system placed in contact with and perpendicular to the conductors, with the window means towards the conductors. On the application of heat and pressure, the solder melts and flows toward the terminals, and solder bridges are prevented by the "window frames" which lie between the terminals.
