Hi Everyone, I need to protect the backside of a flexible circuit where the copper is exposed through the Polyimide through our cupric etcher. The opening is to deep for dry film and if I use liquid resist that thick I cannot get it to strip. Does anyone know of a "peel able" etch resist that might work for this application? Suppliers or vendors are welcome to contact me directly Thanks in advance, Chuck Brummer Siemens Medical [log in to unmask] 818.734.4930 --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 1.8e To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 -----------------------------------------------------
