Abstract: Clamp-like guides are arranged in the interior of a soldering bath container at a distance from each other and distributed across the width of the soldering bath container. Each guide has two guide rods which are spaced from each other by a certain distance and which are connected with each other at their lower ends. The upper final sections of the guide rods project upward from a soldering bath and have deflections at their upper ends which form a narrowing therebetween. The final sections can be elastically deflectable and are supported by support springs. Above the guides, two blast nozzles extend across the width of the soldering bath container and direct hot air jets against the surfaces of printed circuit boards leaving the soldering bath. The width of the narrowing is somewhat larger than the thickness of the printed circuit boards.

Abstract: A printed circuit board solder leveling device comprising guides distributed across the width of the soldering bath container. Each guide comprises opposed guide rods spaced apart a distance greater than the thickness of a printed circuit board so that there is loose contact only of the guides with opposite sides of the board.
