ABSTRACT:
A ceramic soldering element, which is utilized in reflow soldering of electrical components that have a multitude of thermal legs, comprises a ceramic substrate, which is thermally conductive but electrically insulating, has a plurality of heating resistors disposed along an edge of the substrate, which edge forms a soldering edge and an arrangement consisting of metal layers on opposite surfaces of the substrate for applying electrical current to each of the heating resistors.
