Abstract
A method of manufacturing an electrical circuit wiring assembly comprises the steps of preparing a first sub-assembly having a metal board chassis and a first circuit element provided with hard stiff leads, preparing a second sub-assembly having a second circuit element provided with soft thin leads and an eyelet terminal for connecting the soft thin lead to the hard lead by means of a soldered junction, and assembling the first and second sub-assemblies by a soldering operating to form a main wiring assembly. In the second sub-assembly the second circuit element and the eyelet terminal are carried temporarily on an unsolderable mounting tool. The first and second sub-assemblies are temporarily coupled to each other during the forming of the main assembly by means of a coupling tool or jig for applying molten solder to an exposed connecting portion of the eyelet terminal and to portions of the hard and soft leads extending from the eyelet terminal. After soldering, the unsolderable mounting tool and the coupling tool are removed from the soldered main wiring assembly so that a three-dimensional wiring assembly is obtained.
