ABSTRACT:
Each of an array of holes for accepting insertion of push-pins, as in pinboards, connectors, etc. for multistrand electrical and/or optical assemblies, is covered with a pin-penetrative membrane area having a hole-identifying marking thereon. Each such hole-covering membrane area preferably has either a see-through characteristic or suitable marking to enable locating and/or determining the size and shape of the respective membrane-covered hole. The respective push-pins with wires or light pipes attached, as the case may be, are punched through the numbered areas of the membrane into the holes for assembly of the pinboard, connector, or other push-pin-utilizing component.
