Diane, you are "right on". The key to eliminating ESD problems is to make sure that the operator, the work surface, and the ESDS device are at the same electrical potential. Also you must elimanate any static producers from the ESDS area or provide a

Have someone you know but the sales guy doesn't know you know, ask for the same part with no lead. I would not be suprised if the sales guy sang a different tune then. Stephen
