PURPOSE:To mount a plurality of electrodes easily by using a frame connecting a plurality of electrodes. CONSTITUTION:A frame 16 is manufactured by connecting electrodes and terminals in a GTO module by tie bars 15, thus accurately positioing the electrodes and the terminals. The electrodes are mounted in such a manner that ceramic substrates 2 are soldered on a Cu base plate 1 and the frame 16 is soldered on the ceramic substrates 2. The tie bars 15 are removed from the frame 16, at least two GTO chips are soldered on the electrodes of the frame 16, and the GTO chips and other electrodes and terminals are connected by aluminum wires, etc. The electrodes and the terminals are mounted by vertically bending them to the Cu base 1. |
