ABSTRACT:
Disclosed is an apparatus for drying printed circuit boards or similar workpieces. The dryer apparatus comprises an "aspirator" portion of a "blower" portion. The aspirator portion of the apparatus is operative to create negative pressure or suction upon the surfaces of circuit boards as they pass along a fixed conveyor path. The blower portion of the apparatus is operative to pass drying air over the surfaces of the advancing circuit boards after they have been subjected to the negative pressure or suction force of the aspirator. The "aspirator" and "blower" portions of the apparatus may be enclosed in a substantially air-tight housing or cabinet so as to provide for substantially self-contained recirculation of air therewithin.
