Wonder what happened to their DVT program and demonstrated MTBF????? Going to cost them a LOT of cash for that issue with the laptops John Burke (408) 515 4992 -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Paul Edwards Sent: Wednesday, August 27, 2008 11:07 AM To: [log in to unmask] Subject: Re: [TN] FYI Nvidia solder issues I think it the reverse... Sounds like a couple of people thought high lead solders are good for burn-in PCAs... so it ought to work on chip interconnects..

Quote: "What supports the theory that a high-lead solder bump in fact is at fault is the fact that Nvidia ordered an immediate switch to use eutectic solders instead of high-lead versions in the last week of July. Eutectic solders are believed to solve the problem of fatigue cracking."
