The present disclosure generally relates to a printed circuit board assembly that may include a circuit board having a first surface and an opposing second surface. The printed circuit board assembly may also include a first interconnect barrel disposed in the circuit board. The first interconnect barrel may have a first length extending between the first surface and the second surface. The first interconnect barrel may include a first section, and may further include a second section spaced apart from the first section by a first gap having a first depth extending partially through the first length. The printed circuit board assembly may further include a first conductive trace coupled to the first section and a second conductive trace coupled to the second section at a first terminal.

Vertical interconnect design for improved electrical performance

Semiconductor package assemblies and semiconductor packages incorporating an impedance-boosting channel between a transmitter die and a receiver die are described. In an example, a semiconductor package includes a package substrate incorporating the impedance-boosting channel having a first arc segment connected to the transmitter die and a second arc segment connected to the receiver die. The arc segments extend around respective vertical axes passing through a transmitter die electrical bump and a receiver die electrical bump, respectively. Accordingly, the arc segments introduce an inductive circuitry to increase signal integrity of an electrical signal sent from the transmitter die to the receiver die.
