Hi Ioan, Why design a special board for assessing component placement. I would think that your board supplier(s) occasionally have fabricated boards that are scrapped for one reason or another. Why not utilize the scrap of your current production designs (assuming pad layout is not the reason boards are scrapped) to assess component placement. Seems to me that would be a more cost effective approach and would likely be more representative of what your trying to determine. Or am I missing something?
