SYSTEM FOR DISPENSING SOFT SOLDER FOR MOUNTING SEMICONDUCTOR CHIPS USING MULTIPLE SOLDER WIRES

摘要

An apparatus for dispensing solder onto a substrate for mounting a semiconductor chip on the substrate comprises a dispensing body and first and second dispensing channels extending through the dispensing body. Each dispensing channel is operative to receive a separate solder wire to feed the solder wire to an end of the dispensing body facing the substrate. The dispensing channels are further operative to introduce the solder wires in a solid state simultaneously from the end of the dispensing body to be melted upon contact with the substrate which is heated.
