ABSTRACT:
In accordance with the present invention, there is provided a non-fusible web for supporting a plurality of individual solder rings in a predetermined pattern homologous with that of a plurality of solder tails or terminals on which the rings are disposed during a soldering operation. The invention finds particular application in vapor phase condensation soldering. Use of the non-fusible web provides for the simultaneous placement of a large number of individual solder rings, while eliminating the erratic and often detrimental flow characteristics occurring during the instantaneous fusion of patterned chains or strings of solder rings during a condensation soldering operation.
