Was it a stainless steel brush being used to improve the Huntron's electrical probe contact? -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Leland Woodall Sent: Thursday, June 05, 2008 9:15 AM To: [log in to unmask] Subject: [TN] Stainless Steel Contamination Question - Source Nailed! Everyone, After checking every filter, every transfer belt, every reflow oven, and most every square inch of the building, I was able to identify the source of the 10 micron stainless steel that has been giving us such a headache. Just in case anyone ever has the same problem, I thought I'd share the solution with our group. To refresh your memory, we were finding this stuff on top of components, and later inside our Huntron X-Y table inspection machines. We did everything but take a hatchet to the Huntrons, and there was nothing found (of course). While one of the Huntron machine's operator was gone to lunch, I decided to check an item she had left behind on her workstation. I took it to the lab, placed it beneath the microscope, and was astonished to find an identical match to our contamination woes. Before I let the cat out of the bag, does anyone want to venture a guess?
