ABSTRACT:
In order to remove impurities from one surface of printed circuit cards which have been subjected in a seperate step to a soldering operation using fluxing agent the invention suggests a method and compact machine for treating the cards. The method comprises the steps of feeding the printed circuit cards through the machine along a horizontal track and carrying out the treatment in a treating chamber having a plurality of successive treating zones comprising a washing and brushing zone for removing impurities from the lower surface of the printed circuit cards by the action of brushes and liquid solvent, and a subsequent drying zone in which the printed circuit cards are subjected to a hot air flow to remove solvent therefrom, and returning solvent used in the treating chamber to a distiller means mounted in the machine for vaporization and condensation of said solvent in order to obtain pure solvent which is supplied to said washing and brushing zone in a closed cycle.
