Abstract: An electronic package including a base member and associated cover member designed for being positioned together to compress at least two circuitized substrates (e.g., a ceramic substrate and a plurality of flexible substrates) positioned therein. One of the substrates is substantially rigid and is positively positioned in a protected, aligned manner within the base. Additionally, the flexible substrates are precisely aligned and initially secured to the rigid substrate, the invention further using yet another resilient means to act against each of the flexible substrates when the packages fully assemble. The cover is secured to the base to effect final compression of the internal elements. This package may be positioned on and electrically coupled to another circuitized substrate, e.g., PCB.

Abstract: A keying system for assuring the proper sequence or arrangement of cable cards within a card grouper is provided. The grouper includes a plurality of slots to receive the cable cards. The cards include tab means at at least one side thereof which can be selectively trimmed to one of several specific extension distances from the card. The grouper includes a template which has grooves configured to receive cards having their tabs programmed to one and only one configuration. Thus any given card, when programmed, will fit in only one location. The cards and grouper also include coacting surfaces to allow the appropriate card to be inserted in only one orientation in any given slot.
