After fabrication, all copper straps are tested and then ultrasonically cleaned and bagged before shipping.  TAI offers optional nitrogen purged bags for shipping your straps, but we also recommend that any thermal strap used in a UHV, sensitive optical, or space/satellite application, undergo any additional cleaning spec/procedure your organization requires for copper hardware. For example, some laboratory and aerospace customers will perform an additional round of ultrasonic cleaning in a bath of Alconox, Citranox, acetone, or various copper cleaners (and then perform a vacuum bake out), before installation. In rare cases (such as sensitive satellite optical systems), some customers may require their copper straps are cleaned to a specific spec. TAI does contract with a partnering test and cleaning facility to perform the cleaning in these cases. TAI provides a comprehensive range of strap testing services to our clients (some of which are complimentary, and other services are offered at an affordable rate and performed either here at our facility, or by one of our internationally renowned testing facilities). Each assembly will pass quality checks and undergo thermal conductance testing after construction to verify requirements-compliance. TAI's Management, Engineers, and Program Managers have extensive experience with the Quality Assurance processes and qualification that is required by the industry's top primes, NASA, ESA, and JAXA.
