In the case of treatment of printed-circuit boards with fluids, especially during cleaning, etching, metallisation and flushing, in order to achieve treatment which is effective and can be dimensioned precisely in time, the region which is coated by means of a spray nozzle, surge nozzle or a standing wave is bounded by suction devices (24, 25, 41, 42). Said suction devices are provided in front of and behind the application device (28, 38). The spray nozzles and surge nozzles (22, 24, 25) are arranged in a common housing past whose lower periphery the boards (12) to be treated pass horizontally. <IMAGE> |
