Abstract

Molded nest 10, composed of resilient material such as polyvinylchloride, is adapted to clamp and hold a workpiece 17, such as a substrate. In drawing A, the nest includes square aperture 11 having inwardly sloping top and bottom sidewalls 12A and 12B which merge into flat portions 13. Outboard of aperture 11 and extending substantially parallel to flat portions 13 are a plurality of slots 14, one slot for each of the sides of aperture 11. Extending substantially perpendicular to flats 13 and connecting each slot 14 to its associated flat is a bore 15, being situated at the midpoint of the sidewalls of opening 11.

Molded Nest

Molded nest 10, composed of resilient material such as polyvinylchloride, is adapted to clamp and hold a workpiece 17, such as a substrate. In drawing A, the nest includes square aperture 11 having inwardly sloping top and bottom sidewalls 12A and 12B which merge into flat portions 13. Outboard of aperture 11 and extending substantially parallel to flat portions 13 are a plurality of slots 14, one slot for each of the sides of aperture 11. Extending substantially perpendicular to flats 13 and connecting each slot 14 to its associated flat is a bore 15, being situated at the midpoint of the sidewalls of opening 11. In order to permit easy insertion of corners 16 of workpiece 17, shown in phantom in drawings A and C, it is desirable to relieve the upper and lower corners of 15 where it intersects walls 12A and 12B and the flat 13. As shown in drawings B and C, a hole or slot 18 is drilled through walls 12A and 12B and flat 13 to form a relieved portion in the sloped sidewalls, the relieved portions being generally keyhole shaped. Such portions, act as guides for corners 16 of workpiece 17 as it is inserted into bores 15. Upon insertion of workpiece 17 into aperture 11, slots 14, which extend through the material of the nest, provide sufficient resilience to permit compression of the material and help to retain workpiece 17 in its inserted position.
