I am confused at what the current IPC-6012 states regarding Lifted
Lands:
-------------------------
Page 11:
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.
Page 6:
3.3.4 Lifted Lands The Finished board shall not exhibit any lifted
lands
-------------------------
In the old IPC-RB-276 lifted lands was permitted after thermal stress.
Is this an error in IPC-6012 or has there been a change in what is
acceptable?
I'd appreciate any feedback.
Thanks,
