Hi Steve What have you done to minimize your defects? -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Steve Gregory Sent: Tuesday, March 04, 2008 12:19 PM To: [log in to unmask] Subject: Re: [TN] Leadfree trends Hi Inge!

Have had a few more tombstones with LF than I've seen in a long time, and a little more opens due to not wetting as well. But I can't say that I've seen more of the other three defects....
