Abstract: A bench top printed circuit board scrubber apparatus is disclosed having a roller conveyor for transporting varying thickness circuit boards through a scrubbing and drying compartment. The apparatus includes a pivotal top plate which mounts a scrubber brush and its respective motor drive such that the brushing assembly may be extended away from the roller conveyor as a unit to facilitate easy access to the internal components. Additionally, the apparatus provides a quick change mounting means for the roller conveyor, and a compact axial flow air drying system which effectively dissipates water applied to the circuit board during the scrubbing operation.
