About OMNI

Omni Circuit Boards is your source for superconducting cryogenic PCB manufacturing.

If you need reliable superconducting PCBs or PCBs for aluminum wire-bonding, please contact us.

We are familiar with the thermal properties of our PCBs down to millikelvin temperatures, the challenges of thermal cycling, and making superconducting connections to our PCBs.

We are the proud manufacturer of the cryogenic PCBs found in D-Wave quantum computers. These PCBs have operated flawlessly at temperatures down to 10 mK, and have remained in service for years. You can continue reading more about Superconductive PCBs below ↓.

About Superconductive Aluminum-Trace PCBs

Aluminum-Trace Printed Circuit Boards provide the design solution to challenges faced with low temperature superconductive circuit boards and applications where the radiation-absorption properties of aluminum can be exploited.

By successfully developing a process of chemically milling circuit boards with an aluminum circuitry, we are able to provide a design solution to a number of unique applications previously constrained by conventional PCB materials and processes.

The process of producing PCBs with aluminum circuitry is unique and different from the commonly known “Aluminum PCBs”, reason why we refer to them as “Aluminum-Trace PCBs”.

The aluminum circuit begins with ultra-thin sheets of 30 µm aluminum foil. Depending on the customer’s requirements a mere 5 µm film of copper can be layered between the aluminum and dielectric to enhance the thermal conductivity of the device.

A 5 µm copper layer can also be provided on pads on the top side to enhance solderability.

These layered sheets are laminated together to customer specific configurations.

After machining, a series of processing stages produce the fine lines and finally the solder mask and silk screening artwork is provided.

The end product is a printed circuit board with fine-line aluminum traces and solderable aluminum pads which in turn make them superconductive, this is what makes “Aluminum-Trace PCBs” special.
