For use in soldering the backplanes of printed circuit or other type electronic boards, a solder wave generator is disclosed with opposed side jet walls. The side jet configuration, because of opposed jet flow, provides an inertia necessary to balance the side forces and the pressure developed by the central pool of fluid, in this instance solder. The central pool, as supported by the side flow, is nearly stationary and the width of the pool can be varied substantially without increasing the total flow rate or the head of the pumping system.
