Patent ID: 7280372

Claim:
An electrical assembly with a circuit board and at least one integrated circuit package coupled to the circuit board, the electrical assembly comprising: a first dielectric layer; a second dielectric layer with a first surface and a second surface, the first surface disposed adjacent the first dielectric layer, the second dielectric layer having first and second apertures therein to expose respective first and second regions of the first dielectric layer; a first plurality of signal conductors disposed between the first and second dielectric layers and extending from the exposed first region of the first dielectric layer to the exposed second region of the first dielectric layer; a second plurality of signal conductors disposed on the second surface of the second dielectric layer and extending from a periphery of the first aperture to a periphery of the second aperture, the second plurality of signal conductors being electrically isolated from the first plurality of signal conductors; and a first integrated circuit package disposed within the first aperture.
