Is there any guidance in IPC publications about acceptable clearance
between components and mounting hardware? I can't find anything, but one of
our designs has a QFP144 near a screw (more than 100 mils), and someone is
wondering if it will be a problem.

Here is a partial picture:

There's also a crystal to the left of the mounting hole, and they were
wondering about that one, too. Should I be worried?

(always feelin' like "the new guy")
