ABSTRACT:
A solder feeding system including an apparatus for supplying a predetermined number of solder balls to at least one soldering bath once the level of liquid solder in the bath drops below a defined limit. The solder ball is shaped to have a diameter of from 5 mm to 50 mm, preferably 10 mm to 30 mm by casting, forging, or rolling. The number of solder balls added have a volume capable of raising the level of liquid solder in the bath by a distance similar to or less than a range of tolerable upper and lower limits and a thermal capacity to lower the temperature of the liquid solder within a tolerable range.
