Abstract

Systems, methods, and devices for electrically coupling an integrated circuit to a set of coaxial lines via a printed circuit board assembly are described. A device sample holder includes a printed circuit board that is operable to edge-couple to an integrated circuit. A surface of the printed circuit board that carries a set of coaxial connectors is orthogonal to another surface of the printed circuit board that exposes a set of conductive traces. The set of conductive traces are operable to electrically couple to a set of conductive paths of an integrated circuit to provide a communicative path between the integrated circuit and components of an input/output system in a refrigerated environment.

First claim

The invention claimed is:

1. A printed circuit board (PCB) assembly for electrically coupling an integrated circuit to coaxial lines, the PCB assembly comprising:
first PCB having a first surface, a second surface, and a plurality of conductive traces, each one of the plurality of conductive traces having a portion exposed at the second surface of the first PCB;
a first plurality of coaxial connectors carried by the first surface of the first PCB, each one of the first plurality of coaxial connectors having a respective inner conductor, wherein each one of the plurality of conductive traces is electrically coupled to the inner conductor of a respective one of the first plurality of coaxial connectors;
a second PCB having a respective first surface and a respective second surface; and
a second plurality of coaxial connectors carried by the first surface of the second PCB, wherein the first surface of the second PCB is parallel to the first surface of the first PCB.

2. The PCB assembly of claim 1 wherein each conductive trace of the plurality of conductive traces traverses from the first plurality of coaxial connectors towards the second surface of the first PCB.

3. The PCB assembly of claim 1 wherein the first plurality of coaxial connectors includes a plurality of radio frequency connectors.

4. The PCB assembly of claim 1 wherein each conductive trace of the plurality of conductive traces comprises at least one of: aluminum, niobium, tin, and copper.

5. The PCB assembly of claim 1 wherein a distance between the first plurality of coaxial connectors and the second surface of the first PCB is greater than a distance between the second plurality of coaxial connectors and the second surface of the second PCB.

6. The PCB assembly of claim 1 wherein the first PCB includes a third surface, the second PCB includes a third surface, and the third surface of the first PCB is pressed against the third surface of the second PCB.

7. The PCB assembly of claim 6 wherein each one of the first plurality of coaxial connectors faces a first direction and each one of the second plurality of coaxial connectors faces a second direction, and the first direction is different from the second direction.

8. The PCB assembly of claim 1 further comprising a third PCB having a respective first surface orthogonal to the first surface of the first PCB.
