Abstract
The invention features a method for flowing solder in a gap between two surfaces. A supply of solder is heated to cause it to reflow and flow in the gap. The solder is directed to flow as a main stream in the gap and to flow as peripheral streams from the main stream toward edges of the gap to reduce formation of voids.
