solder stain on gold finguers | 23 February, 2001

I would like to have some advise or explaination about the IPC610 spec. Page 6-51 and 6-52 concerning the solder stains on gold finguers:

On the page 6-51, it's recommended to inspect the gold finguers with the unaided eye, but on the page 6-52, the spec are "no solder on critical area...", so with unaided eye, you can't see solder stain if the size of the stains are less than 200-300 � it means that solder stains less than 300 � are accepted ??

Thanks

200-300u that�s tinny but I read IPC as saying ANY metal other than gold in the critical contact areas is not acceptable.
