Induction soldering evaluation
A project is described which began in support of process development work on cables which use electromagnetic radiation (EMR) hardware. These cables require an air tight conductive path between the shield, the adaptor ring, and the connector shell. Solder joint processing between the adaptor ring and connector involves installing a solder preform in the groove between ring and connector and inserting the connector in an induction heated work coil to melt the solder. A typical heat cycle lasts approximately 5 seconds and generates a peak temperature of about 500/sup 0/F. The solder melts and flows into the threaded areas, making visual verification of the solder joint difficult. This investigation measured the temperature difference across the RTV seal in the connector and determined the extent of seal damage from heat. This investigation also determined the effects of subjecting the connector to a 600/sup 0/F peak temperature. Seven work coils were evaluated and a coil was produced which will make a consistently air tight solder joint while minimizing heat transfer to the connector seal. A process and induction heating coil were developed to solder EMR hardware to the adaptor ring while minimizing heat transfer to previously soldered terminations.
