Abstract: A method is provided for forming waveguides in a PCB. The method may include forming an opening in a PCB core comprising a plurality of conductive layers interleaved with a plurality of insulating layers, the opening extending from a first side of the PCB core to a second side of the PCB core. The method may also include filling the opening with metal. The method may also include forming a cavity enclosed by sidewalls by removing a first portion of the filled opening, the cavity extending from the first side of the PCB core to the second side of the PCB core. A second portion of the filled opening is a heat transfer element configured to transfer heat from the first side of the PCB core to the second side of the PCB core. The at least one waveguide is embedded within the heat transfer element and configured for transmitting signals from the first side to the second side.

Abstract: An electrical component, such as an RF device or thermal bridge, for use with a printed circuit board. The component may include a first dielectric layer having a top and a bottom, and a first conductive trace positioned on the bottom of the first dielectric layer. The component may also include a first ground layer positioned on the bottom of the first dielectric layer and spaced apart from the first conductive trace and a first solder layer connecting the first conductive trace to a second conductive trace of the printed circuit board and extending the full length of the first conductive trace.

Abstract: A system for connecting a first electrical connector on a printed circuit card with a second electrical connector. The system includes a support member having the printed circuit board connected thereto; a movement device allowing the support member to move in a first direction relative to the second connector; and a float connection between the movement device and the support member allowing the support member to move in a second direction relative to the second connector. The second direction is angled relative to the first direction. The float connection allows the first connector to align with the second connector as the support member is moved in the first direction and the first and second connectors are being connected to each other.
