Gary, Franklin has a good bundle of instructions. If you want to give it more weight, refer to IPC-4553, paragraph 3.8. Regards, Ioan -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Gary Camac Sent: Thursday, June 01, 2006 10:47 AM To: [log in to unmask] Subject: [TN] Packaging requirements for IAg Finished PWBs Good morning all, I am struggling through a rewrite of our material specification for PWBs. I have seen the recommendation that cover sheets and interleaf sheets should be used to prevent scratches on IAg finished PWBs. Have those that are using IAg seen this as necessary? We eliminated this requirement on Sn/Pb finished PWBs some time ago without any negative effects.
