A holder for supporting a printed circuit board in a vertical plane for movement along a path for treatment of sides of the board. The holder comprises a rigid frame support an means for mounting the frame for movement along the path. The improvement comprises means for mounting an edge of the board at a first position on the frame and a moveable weight bar for mounting a second edge of the board at a second position on the frame below the first position. The weight bar acts to provide a stretching force to the board for aiding and maintaining the board substantially planar during processing of the board as mounted in the frame.

Printed circuit board holder

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.
