     I'm a bit confused (not unusual) by two paragraphs in IPC-6012
     regarding lifted lands.

     3.3.4  Lifted Lands.  The finised board SHALL not exhibit any lifted
     lands.

     3.6.2.9  Lifted Lands.  Lifted lands are allowed after thermal stress
     provided that the visual criteria of section 3.3.4 are met.

     So, is this telling me that lifted lands are okay as long as I can't
     see them?  (If I can't see them, how would I know they were lifted?)
     Therefore, if there is visual evidence of a lift is it rejectable?
     Was the intent to allow or dis-allow lifted lands after thermal
     stress?

     Thank you for any clarification.
