My bane was must coat and must not coat with no transition area. This was for automated dispensing. Even with masking to give a sharp edge, there is a tolerance on the location. Something should be noted as to need for a tolerance or a don't care area between the 2, even if it is up to the individual design to specify it. A paralyene contractor told me he could hold 4 mils. That is not zero and I hate to think of the price to hold that tolerance. For the 100 panel/ an hour shops, it has to be larger. ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
