The Superconductive Circuit Board

    Aluminum Trace Printed Circuit Board Innovation

    The journey to develop a circuit board which features aluminum circuitry (Aluminum PCBs ) has been challenging.

    Beginning in 2008, Omni Circuit boards was challenged by a strategic partner with developing a circuit board with fine-line aluminum traces. The reason for aluminum in the initial quest was for its superconducting (cryogenic) properties. But as time went by, we began to appreciate how developing this capability could also benefit customers who have a requirement for aluminum wire bonding of critical components.

    Development of Low Temperature PCBs

    Mid 2011 was the beginning of the collaboration between Omni Circuit Boards and D-Wave Systems to produce superconducting, low temperature printed circuit boards (PCBs).

    Development was driven by D-Wave’s need for low temperature PCBs which could provide mono-metal superconductive connection to their unique processors. The PCBs would operate at low-temperature, be solderable and be suitable for wire-bonding. The PCB would also withstand multiple temperature cycling from below 500 Millikelvin to 20C.
