I agree with Patricia whole heartedly. However, due to the
complexity of todays product, with lines and spaces going
down to 3/3 and less, it may also be time to take a look at
the requirements placed on our laminate and other material
suppliers. Small dents and epoxy spots (acceptable to IPC
requirements) on copper clad laminate which may not have
been an issue in the past on 10 mil lines and spaces, are
definately an issue with todays 3 mil and less technologies.
