Space Parts Working Group

Last month, Tekmos sent a representative to the annual meeting of the Space Parts Working Group. This is a meeting of government users of satellites, companies that make satellites, and component manufacturers that make parts for satellites. The meeting was for two days, and consisted of presentations from government users and the component manufacturers. It also presented a lot of networking opportunities.

Tekmos sells several products into the aerospace market. We are also working on upgrading our quality system from ISO9001 up to AS9100, which is now being required by some of our customers. After that, the next step is changing our products to offer an even higher level of reliability. And the first stage of that process is to determine what are the limits with current parts. And that is why we were at the Space Parts Working Group.

So, what did we learn? Being space related, radiation damage was a big topic. The higher the orbit, the greater the damage. As a subset of radiation, heavy ions are an increasing concern. Heavy ions are also a problem with the aviation market, and have been identified as a cause of commercial aviation engine failure in at least one instance. Another issue was bond wire integrity, as a result of corrosion, thermal cycle, and vibration during launch. And as with all semiconductor users, there were concerns about obsolescence and counterfeiting. These are all areas that will be addressed as we develop the next generation of Tekmos products.
