An apparatus is provided which comprises: a cavity made in a substrate of a printed circuit board (PCB); a plurality of solder balls embedded in the cavity; and a horizontal trace within the substrate, wherein the horizontal trace is partially directly under the plurality of solder balls and is coupled to the plurality of solder balls and another trace or via in the substrate such that a substrate region under the plurality of solder balls is independent of a stop layer under the cavity.

Apparatus with embedded fine line space in a cavity, and a method for forming the same

This document discusses, among other things, a waveguide including a first metal having an outer surface proximate a dielectric material and an inner surface defining a path of the waveguide, a method of receiving an optical signal at the inner surface of the waveguide and transmitting the optical signal along at least a portion of the path of the waveguide. A method of integrating a waveguide in a substrate includes depositing sacrificial metal on a first surface of a carrier substrate to form a core of the waveguide, depositing a first metal over the sacrificial metal and at least a portion of the first surface of the carrier substrate, forming an outer surface of the waveguide and a conductor separate from the sacrificial metal, and depositing dielectric material over the first surface of the carrier substrate about the conductor.
