Hello All, Tented vias are covered by soldermask to avoid pick up of solder during Wave solering process. I would like to know whether, If Reflow soldering is opted for, is there a necessity of tented vias? Can we not use normal vias( for which the soldermask covering will not be present ) on a board that is being subjected to Reflow soldering process ?
