    Quantum Computer Developer Chooses Omni as Superconductive Printed Circuit Board Manufacturer

    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 next generation of Printed Circuit Boards - Developments in Aluminum-Trace (very low temperature) PCBs

    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.

    What You Should Know About Immersion White Tin Printed Circuit Board Manufacturing

    If you work with printed circuit boards or the PCBA industry, then you have probably heard of Immersion White Tin, but may have questions about how it actually works and whether it's a process that you should care about.

    Given that we are leaders in Immersion White Tin PCB fabrication here at Omni, it goes without saying that we are heavily in favor of its use.

    To understand why, you first have to understand the reason behind our preference for white tin in the first place.

    Traditionally, printed circuit boards have been finished with a coating of material to protect them from oxidation and allow for components to be soldered onto them in a reliable consistent way, this is usually specified to as "PCB Finish" and requires the use of Lead (HASL) and vast amounts of water during processing (All  other PCB finish types). 

    Understanding Printed Circuit Board Manufacturing: Electrical Testing

    PCB manufacturing facilities routinely perform Electrical Testing with “Flying Probe” testers which are well suited to smaller production runs.

    For short runs, the flexibility of quick set-up ensures cost effective Flying Probe tests outperform the lead-time, cost and fixed designs of dedicated test beds.

    With Flying Probe tests, no fixtures need to be prepared, only data files.

    Flying Probe tests are able to reveal not only shorts and opens produced by the manufacturing process but have also been known to expose design errors.

    Printed Circuit Board Finishes - White Tin, Immersion Tin, Immersion White Tin and Whiskers

    Mention Immersion White Tin around sales people from PCB shops and Tin Whiskers will inevitably be part of the topic.

    They may not feel comfortable down mouthing the competition in public but a process? Well that’s fair game. What the salespeople don’t know or won’t tell you is the Immersion Tin used as a finish for circuit boards completely dissolves in the solder used in the circuit board assembly process.

    4 Tips for Saving on Printed Circuit Board Prototyping Costs

    1) Not considering sufficient Thermal and antipad (solder mask) clearances

    You need to consider thermals and antipad (solder mask) clearances on the power &/or ground plane layers of multilayer boards during design. If layer to layer registration, tolerances for hole size, location, film expansion and registration have not been taken into account then manufacturing will experience high reject rates and increased costs.
