Abstract
A printed circuit board conveyor apparatus has a conveyor for moving a planar circuit board components mounted on frames, in a vertical plane, seriatim, along a first path through a spray treatment area. The components are then raised and returned toward a starting point along a second path with additional processing occurring during the return trip. The use of an overhead return along with positive positioning of the components provides substantial efficiency and allows precision and accuracy in treatment of printed circuit board components while minimizing floor space requirements.
