The first thing that I would do is contact the smock manufacturer and ask them for advice on testing the smocks. ESD FROM A TO Z 2nd ed. (Kolyer) states that: smocks should have a resistivity of less than 10^12/sq and must not shed steel fibers.

Hello phil, The use of AOI systems give us the opportunity to auto-collect defect information much the way you're using them now. AOI systems become extremely effective when the collected data is used to perform some positive change into the process.
