The failure mechanism was determined to be tin whiskers emanating from the tin plating on the internal pins. The high conductivity, pure tin crystalline whiskers bridged the 10-mil spark gap to cause the test failures. The fusing current of the whiskers was in the range of the source current of the test equipment. This caused inconsistencies during problem identification and verification at the...
