Mil-STD-883J was released on June 7th 2013 and within that document there was a significant change to the hermeticity test method 1014.14 (Seal). The hermeticity spec limit for space qualified hybrids was tightened by two orders of magnitude. The hermeticity specification for non-space products remained unchanged. TM 1014 is the defacto leak test hermeticity standard and is used and referenced by many companies in the defense, aerospace, telecom, oil and gas and Class III medical implant industries.
New TM 1014 Hermeticity Spec:
This spec change is significant and may require equipment upgrades and will likely affect process yields and therefore cost and schedule. Defense Land and Maritime has allocated a two year implementation window. For the time being this spec change only affects Space qualified Class K hybrids, however, once the test equipment is in place it may well be that down the road the tighter requirement is levied on all hermetically sealed microcircuits. It’s already a requirement for small volume semiconductor devices built to MIL-PRF-19500 performance specification.
