You get what you ask for. We ask for 0.001 inch minimum. If your supplier's published process range allows thickness below 0.001 inch minimum, you need to define your own acceptance criterion.
We don't use average measurements in lot inspection. We assess individual items. If we find defects in a recept lot, we decide on which portion of the lot to reject based on factors including: * Vendor supply history * Our production requirements * Portion of the lot rejected * Replacement part replacement time * etc
