Stainless Steel Hotplate Heater for Long Objects --- Inventor(s): Stephan Jurczynski and Hans Schneider

This is an invention to aid soldering large conductors. High electrical current is passed through a stainless steel plate longer and slightly wider than the conductor to be soldered.  Thermocouples on the underside of the heater provide temperature data for heating control.  A thin sheet of mica electrically insulates the conductor from the heater.  Heater current is adjusted to maintain ramp rates and hold temperatures of the conductor.
