Abstract:
1. A device for treating circuit carriers (PCB) provided with through holes and/or cavities with facilities for contacting the liquid for treatment with the circuit carriers (PCB) as well as transportation means ( 13 , 14 ) for the circuit carriers (PCB), comprising means for conveying the circuit carriers (PCB) in a horizontal conveying path and in one conveying plane ( 2 ), wherein pulse generating means ( 21 , 31 , 40 , 50 ) are provided for comprising means for directly exciting circuit carriers (PCB) via any of (a) the transportation means ( (b) the liquid; for treatment by mechanical pulses, characterized in that the transportation means ( 13 , 14 ) are at least partially equipped with one magnetic core ( 23 ) each and that at least one electromagnet ( 40 ) comprises a pulse generating means to each of the transportation means ( 13 , 14 ) equipped with the magnetic core ( 23 ) whereby current supplied in a pulsed manner to the at least one electromagnet ( 40 ), causes a force to be exerted onto the transportation means ( 13 , 14 ) equipped with the magnetic core in such a way that mechanical pulses are generated in the circuit carriers (PCB) through the transportation means ( 13 , 14 ).
