Abstract:
The process for producing subsequently contactable contact points between two conductive track planes on a circuit substrate separated by an electrically insulating layer makes it possible to produce, for example, a basic conductor pattern which can subsequently be easily adapted to requirements. By laying windows in the conductive track planes out in such a way that, when the electrically insulating layer is subsequently through-etched due to under-etching, rod-like parts connected to the aperture periphery are revealed between or in the apertures which can be brought into contact with electrically conductive parts of the other conductive track plane, these conductive tracks can be electrically interconnected by mechanical bending.
Abstract:
A multi-layer circuit panel assembly is formed by laminating circuit panels (10) with interposers (12) incorporating flowable conductive material (48) at interconnect locations and a flowable dielectric material (30, 38) at other locations. Excess materials are captured in reservoirs (20) in the circuit panels. The flowable materials and reservoirs allow the interposers to compress and take up tolerances in the components. The stacked panels may have contacts (538) on their top surfaces, through conductors (527) extending between top and bottom and terminals (530) connected to the bottom end of each through conductor. The terminals and contacts are nonselectively connected to one another at each interface so that wherever a terminal and contact an adjacent panels are aligned with one another, these are connected to one another. This forms composite vertical conductors extending through a plurality of the panels. The selective treatment of the panel top and bottom surfaces provides selective interruptions in the vertical conductors.

PROBLEM TO BE SOLVED: To provide a method for producing a multilayer circuit unit. SOLUTION: A first circuit panel (544) having a dielectric material body, a contact (538), an electrode portion (530), and a skeleton conductor (527), and a second circuit panel (562) having a dielectric material body and an electrode portion (530) are prepared. A top of the first circuit panel is selectively treated, thereby the panel is specified in a customer-oriented manner; and part of the skeleton conductor of the panel is connected to the contact of the panel, the circuit panels are stacked in a top-and-bottom opposed style, where a top of the first circuit panel faces a bottom of the second circuit panel in a first interfacial area, first patterns on opposed faces are aligned with each other, the contact of the first panel is aligned with the electrode of the second panel in at least part of the aligned pattern, and the contacts and the electrodes, which are aligned with each other in the interfacial area, are all connected non-selectively to each other. Thus, part of the specified panel in the customer-oriented manner is connected to the electrode of the panel. COPYRIGHT: (C)2004,JPO

Abstract:
Electrically conductive elements on two substrates can be electrically interconnected by an adhesive tape containing electrically conductive particles, most of which are substantially uniformly spaced from their six nearest neighbors. Preferably the particles are spherical and of substantially equal diameter slightly exceeding the thickness of the adhesive layer. The adhesive tape can be made by forming a dense monolayer of the particles, covering a stretchable adhesive layer with that dense monolayer, biaxially stretching the adhesive layer to separate each particle from other particles of the monolayer, and then embedding the particles either into that adhesive layer or into the adhesive layer of another tape.
