Abstract

This method is for joining or welding the projecting leads from very small electrical parts to the terminal lands of a substrate. Module 8 is provided with terminal leads 13, 15, 17, 18, 19, and 20, some of which are to be joined to conductive lands 29 and 30 of a substrate. The bonding apparatus includes two electrodes 21 and 23 connected respectively to the plus and minus terminals of DC source 24. For avoiding back voltage current flow through the module which might damage in an undetectable way the parts of the module, the electrodes of the apparatus are positioned along a line substantially perpendicular to the conductor length or major axis. In using such a process, no damage occurs to the parts due to the back voltage which might appear during the bonding step.
