Abstract:
Parallel surfaces are interfacially mechanically bonded and optionally electrically, and/or thermally connected using an interposer (10) fabricated from a flexible laminates, such as flex PWB (12). The bond/connection points (30) for the device made on side of the interposer (10) are displaced in the X and Y axis from the bond/connection points (30) on the other or obverse side for the interposer (10) and the board (12). The optional electrical/thermal connection through the interposer (10) is made through one or more traces (13) and vias (16, 18) in the flex board (12).

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:
Techniques for optimizing application specific integrated circuit (ASIC) and other IC pin assignment corresponding to a high density interconnect (HDI) printed circuit board (PCB) layout are provided. Applying the techniques described herein, pin assignments may be systematically and strategically planned, for example, in an effort to reduce the PCB layer count and associated cost, increase signal integrity and speed, reduce the surface area used by an ASIC and its support circuitry, reduce plane perforations, and reduce via crosstalk when compared to conventional designs with an ASIC mounted on a multilayered PCB.
