Well, let me take a shot... +/-100um = 0.1mm 5 sigma = is the number of acceptable defects (or placements outside of that accuracy (or tolerance). I believe 5 sigma is 233 defects out of 1 million, but I could be wrong on that. So basically all pl

Lead free is not define as NO lead and "a maximum concentration value of 0.1% by weight in homogeneous materials for lead shall be tolerated." Check below link. So replaced your solder from the pot when exceed 0.1%. http://www.leadfree.org/files

RoHS actually allows for up to 0.1% lead in solder. Unless you are really sloppy at cleaning your tools it would be very unlikely that you would get 0.1% lead into your lead-free process (remember leaded solder is only about 50% lead). Regards, Ber
