The method involves transporting the circuit boards (LP) through a treatment unit (1). The boards are moved by pairs of rollers (13,14), in a horizontal transport path and on a transport plane (2) and they are brought into contact with a treatment fluid. An impulse wave generator mechanism (50) transmits mechanical impulses (57) direct to each circuit board, using the transport device and/or the treatment fluid. The strength of the waves is increased by placing plates or foils, to act as reflectors (58) on the side of the side remote from each impulse generator mechanism. There may be two impulse generator mechanisms, one on either side of the path followed by the circuit boards. |
