Don't know of a actual coupon but Specimen E is the "Y" version. Testing for clean boards/panels should be done prior to any soldermask adhesion or conformal coating so you will pass any peel testing. I am sure most fab house claim they have a known good profile of the process so they don't have to verify each panel is clean. www.quickturnflex.com Thank you, Jim Mahoney Quick Turn Flex Circuits, LLC Applications Project Manager P# 603-821-7071 M# 603-305-6250 ** This email and all attachments have been scanned prior to being sent** Confidentiality Notice: This page and any accompanying documents contain information that is confidential, privileged or exempt from disclosure and is intended for the exclusive use of the addressee.
