Semiconductor having soft soldered connections thereto

Abstract

Abstract A transistor wherein the collector contact of a platelike semiconductor of silicon is soldered to a metallic base and wherein the base carries two insulated terminals for coiled first end portions of two wirelike leads whose second end portions are soldered to the base and emitter contacts on the exposed surface of the semiconductor. The second end portion of the leads are parallel to the axes of coiled end portions and the internal diameters of such coiled end portions exceed the diameters of corresponding terminals. The connections between the terminals and the coiled end portions are established by solder which is applied over the coiled end portions in the form of annuli and melts while the parts of the transistor are conveyed through a soldering furnace. During such transport, the second end portions penetrate into soft solder of the base and emitter contacts, and the collector contact of the semiconductor is simultaneously soldered to the metallic base.
