The Superconductive Circuit Board

    Measuring and Calculating the Resistance of Aluminum PCB Traces

    Measuring resistance of a fine-line aluminum trace provides different challenges compared to traces on a copper PCB, most importantly, the surface aluminum oxide is tenacious and it can be difficult to get through to arrive at an accurate and repeatable measurement.

    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 20°C.

    Developments in Aluminum Trace Circuit Boards

    As you might expect, no two applications for aluminum trace circuit boards are the same and most often they are not even similar.

    While some customers are investigating frontiers in MEMS (Microelectromechanical systems), others are delving into the inherent superconductive properties at milliKelvin temperatures, while still others are exploiting the radiation response characteristics of aluminum. For the R&D personnel at Omni Circuit Boards, the requests have presented some interesting challenges.

    Why Omni Circuit Boards Were the First 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.

    Quantum Computer Developer Chooses Omni for Precision Manufacturing
