Abstract

A conductive device for protecting and securing electrical circuit substrates during manufacture and shipment which includes a plurality of spring driven pin slides anchored on a common support member, each slide securing a substrate against a corresponding substrate stop.

Claims

1. A device for securing and protecting generally planar electrical circuit substrates during transport or storage comprising:

a planar support member;

a substrate stop mounted on the support member and having a face for contacting an edge of the electrical circuit substrate;

resilient means mounted on the support member opposite to the substrate stop for resiliently biasing the electrical circuit substrate against the support member and the substrate stop, and wherein the substrate stop and the resilient means cooperate together to force the electrical circuit substrate against the planar support member while simultaneously preventing lateral movement of the electrical circuit substrate relative to the planar support member.

2. A substrate transport device as recited in claim 1, wherein the resilient means comprises:

a spring, the spring being anchored to the support member and positioned so that its line of compression is parallel to the plane containing the support member; and

a pin slide having an face which contacts the electrical circuit substrate, the slide being attached to the spring, the slide being free to move across the surface of the support member driven by the force exerted on it by the spring.

3. A substrate transport device as claimed in claim 2 wherein the planar support member, the pin slide and the substrate stop are conductive.

4. A substrate transport device as claimed in claim 2 wherein the planar support member, the pin slide and the substrate stop are made of polycarbonate plastic.

7. A substrate transport device as claimed in claim 2, further comprising a means for keeping the spring in line with the pin slide, the electrical circuit substrate, and the substrate stop.

8. A substrate transport device as claimed in claim 1, further comprising:

a cover; and

a hinging means for connecting the cover to the support member, allowing the electrical circuit substrate to be fully enclosed during transport.

9. A substrate transport device as claimed in claim 1, further comprising:

a plurality of substrate stops and corresponding resilient biasing means mounted on the planar support member for transporting a plurality of substrates;

a housing enclosing the planar support member;

a cover for the housing; and

a hinging means for connecting the cover to the housing, allowing the electrical circuit substrate to be fully enclosed during transport.

10. A device as claimed in claim 9 wherein the planar support member is one wall of the housing.

5. A device for securing and protecting generally planar electrical circuit substrates during transport or storage comprising:

a planar support member;

a substrate stop mounted on the support member and having an face for contacting an edge of the electrical circuit substrate;

resilient means mounted on the support member opposite to the substrate stop for resiliently biasing the electrical circuit substrate against the support member and the substrate stop, wherein the resilient means includes;

a spring, the spring being anchored to the support member and positioned so that its line of compression is parallel to the plane containing the support member; and

a pin slide having an face which contacts the electrical circuit substrate, the slide being attached to the spring, the slide being free to move across the surface of the support member driven by the force exerted on it by the spring and wherein the pin slide face forms an acute angle with the support member.

6. A device for securing and protecting generally planar electrical circuit substrates during transport or storage comprising:

a planar support member;

a substrate stop mounted on the support member and having an face for contacting an edge of the electrical circuit substrate, wherein the substrate stop face forms an acute angle with the support member;

resilient means mounted on the support member opposite to the substrate stop for resiliently biasing the electrical circuit substrate against the support member and the substrate stop, wherein the resilient means includes;

a spring, the spring being anchored to the support member and positioned so that its line of compression is parallel to the plane containing the support member; and

a pin slide having an end face which contacts the electrical circuit substrate, the slide being attached to the spring, the slide being free to move across the surface of the support member driven by the force exerted on it by the spring.

11. A device for securing and protecting generally planar electrical circuit substrates during transport or storage comprising:

a planar support member;

a substrate stop mounted on the support member and having a face for contacting an edge of the electrical circuit substrate;

resilient means, mounted on the support member opposite to the substrate stop and including a slide member having a face which contacts the electrical circuit substrate, for resiliently biasing the slide member face against the electrical circuit substrate to simultaneously force it against the support member and the substrate stop; and

wherein at least one of the substrate stop face and the slide member face forms an acute angle with the planar support member.
