ABSTRACT:
A tool for use in soldering a single termination of a wire end to a terminal solder tail or other wire end within a dielectric sleeve enclosing a solder preform, and in desoldering a single existing termination needing repair, includes an arcuate tip shaped to be placed against the outside surface of the dielectric sleeve. A substrate of bipartite metal foil is secured along the inner arcuate surface of the formed dielectric tip and has a first layer of conductive metal such as copper and a thin second layer of high resistance second metal having high magnetic permeability such as nickel-iron alloy. When a constant amplitude high frequency alternating current is conducted through the foil, the foil generates thermal energy until achieving a known maximum temperature. For soldering to form a termination, the thermal energy is transmitted to the adjacent sleeve melting the solder of the preform therewithin to join the conductors in the sleeve. For desoldering the thermal energy is transmitted through the sleeve to remelt the solder of the termination, after which the conductors are pulled apart. The tool can have replaceable tips of different shapes and sizes; each tip has embedded wire portions extending from foil ends to a pair of contacts at the mounting end matable with contacts in the tool handle to connect to the cables of the current source.
