Abstract: A singulation system wherein a multiplicity of circuit board members, or the like, can be fabricated by assembling components in a predetermined array on a large planar board-like member with portions of the large member defining independent circuit board assemblies which are separated from each other by intervening slots. The system includes readily adjustable punch and die plate members and accomodating platens which accomplish separation of the independent board assemblies from the large board arrangement without damage to the components mounted thereon.

Abstract: A stacker-loader is positioned at the end of a conveyor line for receiving printed circuit boards as they follow each other in series or sequence along the conveyor. The stacker-loader converts the series of boards into a stack of boards, one aligned over the other on a cart which may be removed. The boards are so stacked without any one sliding over another, since the conductive strip lines on confronting boards might catch on each other. The stacker-loader comprises a field of driven rollers for the enabling of the boards to sequentially travel in series one after another when they leave the conveyor. A pair of spaced parallel cantilever arms are positioned to receive, between themselves, each of the printed circuit boards as it is delivered from the field of driven rollers. An aligned plurality of wheels are mounted on and extended from confronting surfaces of the cantilever arms for supporting the boards as they move along the arms.
