    The technical expertise needed to build the world's first commercial quantum computer is immense.

    D-Wave Systems Inc. turned to Omni Circuit Boards to help them build the first "Superconductive Aluminum-Trace Printed Circuit Boards" that serves as interface with their QPUs (quantum processing units)

    The collaboration began in April of 2005, with Omni providing cutting-edge prototype aluminum-trace printed circuit boards incorporated in the initial set of D-Wave quantum trials.

    As D-Wave's needs grew throughout the process, Omni increased design and production capabilities every step of the way to meet R&D demands.


    The Challenge
    Our challenge was multifaceted, and began with the need to determine the materials and processes required to manufacture printed circuit boards that could meet a number of needs, including:

    • PCBs with the ability to operate in a cryogenic vacuum (very low temperature, the goal is to reach 4 Kelvin)
    • The strength to withstand the rigors of reliable cycling between room temperature and temperatures colder than those found in deep space, over four orders of magnitude in temperature change
    • The versatility to enable multi-component superconductive interconnects
    • The ability to meet D-Wave's aggressive space and trace width requirements
    • The need for construction with PCB materials and processes that would support superconductivity reliably
    • The need for reliable PCB wire-bondable pads 


    The Result
    Through an intense collaborative effort, spurred by innovative thinking and technological advances, our team has produced a fine line, immersion white tin finish, aluminum-trace, printed circuit board. The process for manufacturing each specific board depends on the necessary part and application, but typically requires edge plating, mask over white tin, and a selective gold and white tin finish.

    The Next Step
    Research and development of superconductive materials in the manufacturing of printed circuit boards is ongoing to support the next generation of D-Wave superconductive ICs. While this effort continues to test Omni's technical capabilities in CAM, machining, and chemical processes, it also adds to our ever-growing base of technical expertise and client-focused abilities.
