We caution customers with small via requirements that the hole may close, not
due to copper plate, but rather to solder (HASL) plugging the hole
intermittently. (we use a vertical leveling system)
X-section studies on our 15 mil finished vias indicate our copper plate to be
consistant and even.
Am I alone on this?
