We currently design boards with 8 mil. traces. We have recently tried to go to 6 mil. traces and found that we had reliability problems from batch to batch. What is the smallest trace that is considered reliable by todays standards? Is it just our PCB/PWB manufacturer that may have a problem. Typically what we saw was over etching of the traces. Thank you. Best Regards, Mike Forrester LeCroy Corp.
