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.
