Hermetic Seal/Gross Leak Testing
Commercial tests for device hermetic seal integrity generally follow Military Standards 883-1014, 750-1071 and 202-112. Fluorinert liquids conform to these Military Standards.
Three different types of gross leak procedures are included in these Military Standards, confirming reliability to 10-5 atmospheres per cc/sec or more. Before the availability of Fluorinert liquids, gross leak testing reliability was limited to 10-3-10-4 atmospheres cc/sec.
With these tests, users can determine the hermetic integrity of electronic device housings. Two procedures are bubble tests and vapor detection, with escaping cavity gas identifying faulty units.

3M Gross Leak Testing(测漏)主要用于电子零部件(IC,LSI部件)或者电子装置的气密性测试。3M氟化液FC-40,FC-43,FC-72,FC-84都可以作为测试液使用。并列为美国军方测试标准( Military Standards 883-1014, 750-1071 and 202-112.),一般情况下用FC-40/FC-43测试10(-3)atm cc/sec的间隙,如需要测试更加高精度的部件,可以搭配FC-72,FC-84精确度可以达到10(-5)atm cc/sec的间隙
