Looking in IPC A-600F, section 3.3.2, lifted land is NOT allowed in
cross-sections in the as received condition.
However if you board has been to any heat cycle (including soldering and
unsoldering)... It cannot be rejected.

See also IPC-6012, sections 3.3.4 and 3.6.2.9.

So the question is... Did you do anything to your section first?

This is my first message on the list.
My name is Rajesh and I am a Production engineer in a PCB manufacturing
company in India.

Of late we have been bugged by a problem called Pad lift / Land lift.

I am sending an image with the message so that you guys can visualize it.

I would be grateful if any body can share his/her experience with this
problem.

Rajesh Goutham.
