Making Sub 3/3 A Reality

May 14, 2014
Mythbusting the Semi-Additive Process Prudent PCB designers used to have good reasons for avoiding trace widths and spaces smaller than 3 mils beyond very short spans. But the 3 mil limitation is now becoming a thing of the past, thanks to the use of semi-additive fabrication by some board manufacturers.
