Applies liquefied soldering mask to designated terminal areas of printed circuit boards (PCB's) to prevent molten solder from collecting on circuitry during wave soldering process, using squeeze bottle of soldering mask, and following premasked sample. Removes excess mask from PCB's, using towel. Places masked PCB's in storage racks for movement to next work station.
