Open the CIPO recordAbstract From the Canadian patent
A solder levelling machine which uses a hot gas emanating from opposed gas knives to remove excess molten solder from a printed circuit board as the board is withdrawn from a bath of molten solder contained in a selfpurging solder pot. The hot gas clears the through-holes in the circuit board and allows a controllable desired thickness of solder to remain on the board and in the through holes. A pair of heaters supplies the hot gas to the knives through a manifolding arrangement.
