Abstract

This interconnection arrangement us es C-shaped clamps 20 and ribbed section memory plane hold-down bars 21. The latter encircle adjoining memory plates 19. Bars 21 carry screws 24 and 25 for exerting pressure against padding 27 to press etched copper interconnection lines 28 into place for establishing electrical interconnections between adjoining memory plates 19 and adjoining ground plane 31. The packaging of the coulpled film or bulk memory involves such interconnection of memory plates 19 so that they may be driven by the same circuitry. It is also desirable for servicing purposes that the sections of the memory which are to be changed can be quickly and easily replaced. This mode of screw-clamped connection affords such a mode of separation and replacement of various memory sections.

Interconnection Coupled Film Memory Plates

This interconnection arrangement us es C-shaped clamps 20 and ribbed section memory plane hold-down bars 21. The latter encircle adjoining memory plates 19. Bars 21 carry screws 24 and 25 for exerting pressure against padding 27 to press etched copper interconnection lines 28 into place for establishing electrical interconnections between adjoining memory plates 19 and adjoining ground plane 31. The packaging of the coulpled film or bulk memory involves such interconnection of memory plates 19 so that they may be driven by the same circuitry. It is also desirable for servicing purposes that the sections of the memory which are to be changed can be quickly and easily replaced. This mode of screw-clamped connection affords such a mode of separation and replacement of various memory sections.

The package consists of outer C-section frame 20, common ground plane 31, upper rib section 21, several interconnection bars 26, and strip lines 28 for interconnection with the outside drivers and sensing equipment. All electrical contacts are pressure contacts, except for certain contacts. The latter are between individual ground planes and also between the individual ground planes and the common ground plane 31 where conductive cement or silver paint followed by a pressure contact can be advantageous. The package can be made to accommodate as many individual memory planes as desired.

At each point where four plates 19 meet, there is a square shaped extension 30 a...
