Hello.
If diameter of “via” hole is 0,5mm then minimum diameter of the “via” pad = ?
Sorry. Now I’ve found on the forum these specifications.
It is via hole = 0.3mm and via pads = 0.6mm.
NEW: what is the minimum distance from the conductor to the edge of the board ? 0.1524mm?
ITead Studio, who uses the same manufacturer as Seeed Studio, specifies copper to edge clearance as > 0.3 mm.
