Date 10/3/97 Subject Gen- Cu protective coating From Maurice Dore To technet Gen: Cu protective coating quality 11:45 10/3/97 hi all I have used a test to determine the imidazole based protective coating on Cu by applying ferric chloride to the Cu (Ref: IPC-TM-650 2.3.22) The result has shown a tarnish in different areas of the pads. Does anyone out there use this test to check the coating on the Cu?
