We have already reduced the pad width from .050" to .040" based on input from vendor. Defects appear to be random as far as location on the PWB and direction of placement. We are considering going to a pad width of .035" or less. Is anyone running this type of part without any problems? Is pad size the real key? Is there a recommended pad size? </div> </div>
