: - Via Keepout: prevents a via being placed on that layer. - Via Hole Keepout: allows a via to be stop on that layer, but prevents it passing through the dielectric layer below that layer

(no thermal reliefs), the solder cools before it goes all the way through the hole and out the back side. Some people are concerned about avoiding problems and they do not assume anything and pay extra to plug the via holes. The

"Proper Metric Etiquette" from PCB Libraries It list the VIA to Track selection and good VIA hole to Pad info too. Actually it would be nice if the Optimal VIA Padstack information could be expanded to include wider traces, at the present it covers up to 0.15 mm traces
