Abstract

The fixture presses two printed circuit films 2, in close proximity to a thin film memory plate 1, without flexing films 2. Films 2 are used to read binary data into and out of memory plate 1. When flexure of the films 2 is minimized, their lifetime is materially increased.

Contact Fixture for Thin Film Memory Plate

The fixture presses two printed circuit films 2, in close proximity to a thin film memory plate 1, without flexing films 2.

Films 2 are used to read binary data into and out of memory plate 1. When flexure of the films 2 is minimized, their lifetime is materially increased.

To insert plate 1 into the fixture with minimum flexure of films 2, top plate 3 is removed. Then plate 1 is rested on top of films 2. These are supported underneath by base 10 and by rubber pad 7 resting against pressure plate 8 which, in turn, is held by retainers 9. When plate 8 is resting against retainers 9, rubber pad 7 is not compressed, but is thick enough to provide in combination with base 10 a level support surface for films 2.

After plate 1 is inserted, top plate 3 is tightened against surface plate 4 by screw 5. Plate 1 and surface plate 4 then present a level upper surface to films
2. Thus, when plate 8 is pulled up by screw 6, pressure pad 7 presses films 2 against the memory plate 1 without flexing them around irregular surfaces.
