Abstract:
The present disclosure relates to a method of integrating a interposer device with a textile layer, wherein the interposer device is a stretchable interposer device comprising a stretchable electrically conductive structure with at least one contact pad for establishing at least one electrically conductive path towards the textile layer. The interposer device is arranged to be mechanically attached to a textile layer comprising a plurality of yarns, at least one of which is an electrically conductive yarn. An electrical connection is established between the at least one conductive yarn of the textile layer and the at least one contact pad, which electrical connection is established after the interposer device has been mechanically attached to the textile layer.
Abstract:
A printed circuit board that includes conductive layers separated by insulation layers of dielectric material, at least one conductive layer being patterned and having at least one signal line embedded in an insulation material, whereby a conductive ground plan layer, separated by the insulation material and lying in a predetermined distance (d) from the at least one signal line includes a ground plane area associated to and extending along the at least one signal line, the conductive layer associated to and extending along the at least one signal line is provided with openings therein. Preferably the openings are spaces between conducting stripes, extending, seen from above, across the at least one signal line, the conducting stripes being integrally connected with the conductive remainder of the conductive layer.
Abstract:
An integrated circuit substrate is designed and fabricated with a selectively applied transmission line reference plane metal layer to achieve signal path shielding and isolation, while avoiding drops in impedance due to capacitance between large diameter vias and the transmission line reference plane metal layer. The transmission line reference plane defines voids above (or below) the signal-bearing plated-through holes (PTHs) that pass through a rigid substrate core, so that the signals are not degraded by an impedance mismatch that would otherwise be caused by shunt capacitance from the top (or bottom) of the signal-bearing PTHs to the transmission line reference plane. For voltage-plane bearing PTHs, no voids are introduced, so that signal path conductors can be routed above or adjacent to the voltage-plane bearing PTHs, with the transmission line reference plane preventing shunt capacitance between the signal path conductors and the PTHs.
