Inserted components for via connection of signal tracks to achieve continuous impedance matching in multi-layer substrate

摘要

A technique for connecting signal tracks within a multi-layer substrate is disclosed. In one embodiment, the technique is realized by providing an opening in a substrate and fitting an inserted component into the opening. The inserted component comprises a dielectric block mounted to a lead frame. The lead frame is conductive such that a signal layer formed between the inserted component and the substrate connects signal tracks on multiple signal layers of the substrate.
