Abstract:
1. A wave soldering bath comprising a bath body, a nozzle disposed in the bath body, a pump chamber disposed in the bath body and fluidly communicating with the nozzle and having a bottom plate having an inlet formed therein, a pump disposed in the pump chamber above the inlet, and a shielding member disposed below the inlet between the inlet and a bottom inner surface of the bath body and spaced from the bottom plate of the pump chamber and from the bottom inner surface of the bath body and shielding the bottom inner surface of the bath body against erosion when a vortex develops below the inlet, the shielding member having an outer periphery which has a peripheral edge and which extends around a region on a top surface of the shielding member which surrounds a vertical projection of the entire inlet onto the shielding member, wherein molten solder in the solder bath can flow along a horizontal flow path extending continuously between a point inside the bath body located radially outside the peripheral edge of the shielding member with respect to a center of the pump and a point below the inlet between the shielding member and the inlet.
