The surface copper thickness shall not be less than 20% of the finished
minimum requirement. This is basically for foil tolerance and
processing tolerances. IPC-6012 Class 2 and 3. Section 3.5 is
conductor definition. Watch for impedance requirements, this could
affect the resulting performance.

Hello,
Is there an IPC spec or some other industry standard for "surface bites"
or "dish downs"? How big of a "bite" is acceptable?
