US Patent:

42297788, Oct 21, 1980

Filed:

Mar 26, 1979

Appl. No.:

6/024275

Inventors:

Ernest E. Williams - Fullerton CA
William M. Brennan - Chino CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

H05K 1304

US Classification:

361399

Abstract:

The invention comprises a universal circuit board holding apparatus having a frame with side, front and rear rails. Adjustably positionable rails extend across the frame between the side rails and they are movable in the direction of the front and rear rails. Releasable clamping means engage the side rails and the adjustably positionable rails, permitting movement of the adjustably positionable rails along the side rails when released and for automatically locking the adjustably positionable rails to the side rails when clamping. Circuit board supports are carried by the adjustable rails and either or both of the rear and front rails. Further releasable clamps positionably fix the circuit board supports to the rails while permitting movement therealong upon release to accommodate various sized boards.

Filed:

Jun 25, 1979

Appl. No.:

6/051774

Inventors:

Ernest E. Williams - Fullerton CA
William M. Brennan - Chino CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

B25B 124

US Classification:

269 43

Abstract:

The invention is a work holding system for adjustably receiving and holding printed circuit boards for automatic machine component insertion. It includes a frame and a plurality of mutually cooperative adjustable board holders. The frame is U-shaped and is made up of framing members each having a linear scale affixed thereto. An adjustably positionable framing member extends across the U and is slidable along the opposed framing members toward and away from the base framing member forming the bottom of the U. Means are provided for indexing, locking the adjustably positionable member to the frame in any desired position. A linear scale is also carried by the adjustably positionable member and all scales have a common datum. The frame carries indexing means to index it to the machine which inserts components. A number of adjustable board holders are slidably carried by the base framing member and the adjustably positionable framing member to receive circuit boards therebetween.

Appl. No.:

5/508007

Inventors:

Ernest E. Williams - Fullerton CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

C23C 1312

US Classification:

118 49

Abstract:

A metal coating is deposited upon the surface of a number of electronic circuit device wafers in an evacuated chamber by means of tooling that rotates the wafers about three different axes. A primary three-armed spider rotates about a primary axis and carries on each of its arms a four-armed secondary spider holding a wafer on each of its arms. Four of such primary spiders together with the secondary spiders mounted thereon are carried respectively by four upright standards that rotate in unison about a vertical axis of a cloud of metal vapor filling the chamber. Rotation of the standards causes rotation of the primary spiders relative to the standards and also rotation of each secondary spider relative to its primary spider. The arrangement causes each wafer to sweep up and down along outer portions of the metal vapor cloud as it rotates about the vertical axis of the cloud and also causes each wafer to rotate about its own axis several times for each up and down sweep. An optimum acute angle between the surface of each wafer and a line from the wafer to the source of metal vapor cloud remains within a narrow range during all motion and at all positions of each wafer.
