I would recommend taking a real close look at your preclean method prior to resist lamination. Do you perform water break tests regularly to insure that the surface is free from contaminants. You should also check your resist laminator for any problems, there may be nicks or cuts in the rubber surface of the Hot roller. Also check with Morton regarding the required preheat and exit temperature for HG20. Next, check your breakpoint often and make sure you are not overdeveloping your product. More likely than not, your problem lies in your precleaning and resist lamination process and not in imaging or developing process. -Josh Moody Merix *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * ***************************************************************************
