ABSTRACT:
An apparatus for applying molten wax onto a printed circuit board travelling along a predetermined transfer path. The applied wax after solidification serves to fix the electric components mounted on the board, facilitating the succeeding operations such as cutting and soldering. The apparatus includes a vessel for containing a molten wax, a plurality of ejection nozzles arranged in a direction transverse to the transfer path, valve means connected to each of the ejection nozzles and operable so that the molten wax is ejection from each nozzle upon actuation of the corresponding valve means, and a pump, such as a gear pump, having a suction side in fluid communication with the vessel and a discharge side in fluid communication with each of the valve means. Means are provided for selectively rendering the valve means operable according to the width of the printed circuit board.
