    All,If any of you is involved on IC electrical testing activities. Please, answer below questions:* Do they perform a final outgoing electrical function (qa sampling after testing 100%)?
    * If so, Why do they perform this? is it for philosophy, customer requirements, etc?
    and if they do, What is the statistical basis for the qa sample (AQL, sample size, frecuency, etc)?
    * Do they have a reduced sampling plan for robust/mature products?
    * Are the test parameters & test conditions for final test and qa-sampling the same?Regards,
