Abstract
A device for cleaning or chemically treating workpieces, particularly printed circuit boards with solutions applied to the workpieces by nozzles comprises a two-part housing, the lower portion of which is supplied with a treatment solution and is communicated with the upper part which is subdivided into two chambers by a separating wall. Each chamber is limited from the upper wall of the housing by a flat perforated wall through which the solution flows to the nozzles formed by elongated slots.
