ABSTRACT:
The devices and methods of the art do not readily allow moistening of, removing gas bubbles from and/or increasing the transfer of material in through bores and/or pocket holes in printed circuit boards (PCB). Considerable problems are presented by the treatment of very narrow bores with high aspect ratios in particular. To overcome this problem a method was found that involves the following stages: the printed circuit boards PCB are passed through a processing plant on a horizontal conveying path and in one conveying plane2by means of transportation means13, 14and are thereby brought to contact a liquid for treatment, wherein mechanical pulses are directly transmitted to the printed circuit boards PCB via the transportation means13, 14and/or via the liquid for treatment by means of pulse generating means50.
