Abstract
The selective wave soldering apparatus (101) of the present invention permits wave soldering of select components on a printed circuit board. This is accomplished by narrowing the flow of solder from the wave solder apparatus and creating the proper back pressure on two sides of the flow to form the proper height wave. The back pressure is created by an extended, angled lip (102) on one side and a trough (103) on the side opposite the lip. The trough (103) is open on top and has small openings in one end to slow the flow of molten solder from the trough (103).
