Abstract:
An adhesive interconnection device of Figure 2 (115) providing a simplified simultaneous electrical and mechanical interconnection using one preformed member, comprised of a pattern of non-pressure activated electrically conductive adhesive members (140) and nonconductive adhesive members (145), which must be aligned with the conductive pads of at least two planar electrical devices (100 and 105). Sandwiching the device (115) between at least two electrical devices causes simultaneous electrical conduction paths and mechanical bonds (230) between the two electrical devices. An additional heat curing step may be introduced to achieve the proper conductivity level in the electrically conductive members required for a specific application.

Abstract:
A substrate structure (10) having contact pads (14) is mounted to a circuit board (70) which has pads (74) of conductive material exposed at one main face of the board and has registration features (78) which are in predetermined positions relative to the contact pads of the circuit board. The substrate structure (10) is provided with leads (34) which are electrically connected to the contact pads (14) of the substrate structure and project from the substrate structure in cantilever fashion. A registration element has a plate portion and also has registration features (78) which are distributed about the plate portion and are engageable with the registration features (76) of the circuit board, and when so engaged, maintain the registration element against movement parallel to the general plane of the circuit board. The substrate structure is attached to the plate portion of the registration element so that the leads are in predetermined positions relative to the registration features of the registration element. The registration features of the registration element are brought into engagement with the registration features of the circuit board, and in this position of the registration element the leads of the substrate structure (34) overlie the contact pads (74) of the circuit board. A clamp member (90) maintains the leads in electrically conductive pressure contact with the contact pads of the circuit board.
Abstract:
L'invention concerne les moyens de connexions entre des éléments de commande de petites dimensions -circuits intégrés- et des éléments commandés de plus grandes dimensions -têtes d'écriture ou panneau d'affichage-. Dans le but de réaliser une connectique de multiplexage simple, fiable et ne comportant qu'un seul niveau de conducteurs, le circuit souple (14) sur lequel sont portés les éléments de commande est directement utilisé comme moyen de connexion, et certains conducteurs sont dérivés (22), à la surface des pastilles (12) de semiconducteurs, pour éviter les croisements de liaisons multiplexées. Application aux dispositifs répétitifs à résistances chauffantes, photodiodes, plasmas, pour têtes de lecture ou écriture, ou pour panneau d'affichage.
