Npth vs pth
WebHowever, this is different for non plated through holes. Therefore, PTH offers more benefit than NPTH. Another difference between PTH and NPTH is in terms of area and cost. It is more expensive to design plated through holes circuit boards. Plated through holes take less space compared to non-plated through holes.
