ABSTRACT:
The apparatus for treating and/or cleaning an object, especially a circuit board, with a flood flow of fluid comprises means for moving the object along a path in the apparatus and a number of flood flow devices past which the object is moved on the path, all of which are located above the path. A fluid damming means, preferably a pressing roll contacting the path, may be provided on each of the long sides (the sides transverse to the feed direction) of each flood flow device so that in operation a fluid pool arises around each flood flow device. The flood flow device advantageously comprises a plurality of fluid feed pipes, a fluid receiving chamber of a larger diameter than the feed pipes receiving fluid from them, a perforated mask located downstream in the fluid receiving chamber provided with a plurality of through-going holes and a distributor chamber provided with an outlet mouth located downstream of the perforated mask, the distributor chamber with the outlet mouth and the path defining a flooded space above the path. The fluid receiving chamber, the distributor chamber, the outlet mouth and the flooded space extend substantially over the entire length L of the flood flow device.
