<p>In a method for cleaning of printed circuit boards (3), with any related components, while being submerged in a cleaning fluid the board is cleaned by spraying a cleaning fluid at high pressure on to one or both sides of the board (3). After cleaning the board (4) is removed from the bath for rinsing and drying. The fluid is sprayed in the form of solid, coherent jets (4) from at least one row of nozzles (2) with an angle of incidence of 90 degrees ± 45 degrees to the surface of the board. The jets (4) are sprayed from nozzles (2) which are kept at a distance of between 1 mm and 250 mm, preferably between 1 mm and 50 mm from the surface and moved in such a way that the points of impact on the surface remain spaced between 1 mm and 100 mm apart, preferably under 50 mm. A description is also given of an apparatus for use by the method.</p> |
