Self regulating temperature heater carrier strip

Abstract From the Canadian patent

Simultaneous solder connections of multiple electrical terminals to respective electrical leads is achieved by conducting thermal energy from an actuable heater body to the multiple connection sites via the terminals themselves, the terminals being formed integrally with the heater body. The terminals are scored, perforated etc. to facilitate severance from the heater body after soldering. The preferred heater body takes the form of a copper substrate having a skin depth surface layer of magnetically-permeable, high resistance alloy. Alternating current of constant amplitude and high frequency is passed through the heater body and concentrated in the surface layer at temperatures below the …
