I would think that even a good tight mill isn't going to do a great job circle-milling a under-0.040" hole. If I was making the PCB I'd let the milling machine drill all the holes the same size, so they are located accurately. Then stick a number drill in either a drill press or even a dremel and enlarge the ones that need to be bigger. 4 to 7 holes would be done in a couple of minutes. -- John Kasunich [email protected] ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
