Hi Technetters,
    The evaluation of thermal shock which is descibed in IPC-6012A is that an increase in resistance of 10% or more shall be considered a reject between before test and after test. But I don't know that this is in ambient temperature, high temperature or both. Please tell me the correct evaluative rule.
Thanks!

Best regards,
