Hi Victor,
Use this method: http://www.ipc.org/4.0_Knowledge/4.1_Standards/test/2.4.1E.pdf and examine the tape under a 30X microscope. Poor plating issues typically are discovered by observing small pieces of the gold plating (or worse) on the tape.

Subject: [TN] Copper Peel Test
Fellow TechNetters:
I have been presented with an opportunity to excel. Has anyone out there conducted a Copper Peel Test om gold fingers on PWB/DIMM/Options cards. The Cu peel test that I am accustom to is on laminate cores. Is this a viable test on very small real estate/surface area.
