The Superconductive Circuit Board

    Why Omni Circuit Boards Were 1st to Produce an Aluminum Trace PCB

    Today's computing technology is rapidly outpacing the capabilities of standard, mass-produced printed circuit boards. That's why it was no surprise when the engineers at British Columbia based D-Wave Systems came to us looking for a unique product.

    With quantum chipsets that operate in a cryogenic environment, they needed something more than an "off-the-shelf" PCB that could stand up to the job.

    The resulting product, developed through many months of collaborative research, design, and testing, was an aluminum trace PCB combining aluminum-on-aluminum wirebond pads and solder-on-aluminum connectorization. The entire electrical path is superconducting below 500 milliKelvin temperature, and tolerates repeated cryogenic temperature cycling without breaking wirebonds.

    The superconductive aluminum PCB itself represents a true breakthrough for advanced computing platforms. Although aluminum had been used in PCB production in the past, ours is the first known example of a true aluminum monometal wirebond connection model, rather than one that uses aluminum simply to diffuse heat from copper within printed boards. It's a product and solution that didn't and couldn't exist just a few years ago, and we are proud to have been on the leading edge… and to have met the rigorous needs of a client that's using advanced technology to change the processing world.

    Beyond being a monumental achievement, we feel the aluminum trace PCB highlights three unique strengths within Omni Printed Circuit Boards:

    The strength of our products and technical capabilities. The fact aluminum trace PCBs had been attempted in the past, but unsuccessfully, speaks volumes about our technical capabilities. Regardless of the specific product needs and tolerances, we feel confident in our ability to deliver the right solution. Despite the initially untested nature of the aluminum-on-aluminum board, for example, current breakage rates are less than .1%. If you need the same kind of precision and dependability in your lab or facility, Omni can help.

    The determination and creativity of the Omni research staff. During their initial search for a versatile PCB solution, the team at D-Wave Systems wasn’t just unable to find the printed circuit board they needed, but also to find another firm that was willing to take on the challenge. Despite the fact the need for creative products is growing – especially within the fields of quantum computing, custom chipsets, and cryogenics – the standard approach for most PCB designers and manufacturers has been to produce "stock" PCB boards at low margins, rather than attempting to break new ground in the industry.

    Our commitment to custom, individualized PCB solutions. Although the D-Wave Systems example might be an extreme one, the team at Omni Printed Circuit Boards have developed a reputation for thinking about future solutions and possibilities, rather than attempting to fit existing products to the wrong applications. In other words, researchers and engineers turn to us because they want the best in PCB design and prototyping, along with quick and efficient service, not because they're looking for the same kinds of boards they can get anywhere else.

    As proud as we are of this achievement, and all it means for our team and company, we look forward to working with new products to further test the possibilities of printed circuit board technology.
