Cheers Protel Group! 1. Since I am using a small via to make routing SMT easier. Small via having a 10 mil dia. annular ring (pad of 31_21). Am I free to reduce the annular ring on other parts without any harm. Specificly, reducing a Pad of 75 with a drill of 43, to a Pad of 61 with a drill of 43? A pad of 61_43 would make a connector much easier to route. Board info: So far I'm trying to keep the PCB at space 9 mil minimum, trace of 9 mil minimum. 2. Will I save money by using a Via of 31_21 only when necessary and using a Via of 50_28 everywhere else. Thanks in advance!
