  • Low inductance circuit apparatus with controlled impedance cross-unders and connector for connecting to backpanels
    Patent number: 5161986
    Abstract: Circuit apparatus comprises an integral structure of first and second multilayer wiring board portions and a flexible circuit portion. The wiring board portions each have at least circuit trace planes, ground planes and insulator planes. The flexible circuit portion includes at least one signal trace plane and at least one ground plane separated by at least one insulator plane; the singal trace plane of the flexible circuit portion being integral with a signal trace plane of each of the wiring board portions, the ground plane of the flexible circuit portion being integral with a ground plane of each of the wiring board portions, and the insulator plane of the flexible circuit portion being integral with an insulator plane of each of the wiring board portions. Selected ones of a plurality of electric contacts are connected to selected ones of the circuit traces of the circuit trace plane of the flexible circuit portions; others of the contacts being connected to the ground plane.
