They work well in silver conductive epoxy in hybrid applications. They are very poor in no clean applications. They don't work that well in OA solder paste either. Used them once in OA paste and in a nitrogen. They looked just fine. Solder to Pd

The temperatures were measured on the board, ~1/2" away from the components in question. Admittedly the profile is on the bottom end of the Alpha recommendations. The profile was set up this way intentionally to avoid heat damage to other components

I am currently using a sanyo V850 machine. We are haveing problems with the upline and downline communication from the sanyo to any other conveyor. The conveyors we have on hand all use smemma, and the sanyo has an adapter box that connects to the sm

I was trying to hide my shame on that one, but we have seen failures that we attributed to moisture issues as well. There was nothing to see with the x-ray, but the BGAs didn't work. Replaced the parts with some that had been properly stored/baked

VIP 98, I believe that's a 7 zone if I can remember 6 years ago. Try 150, 165, 200, 235, 235 and 235 (top and bottom temps) with a belt speed of 35 inches per minute. This should get you in the ball park depending on the size of your board.

I hope so, my reply wasn't that funny. Although my new process of boards that grow their own parts by exposing them to B.S. has been so successful that we no longer need breakaways. They all totally green since they are organinc as well! P.S. Moo

Thanks Pete, I wish every video for each piece of I bought went as smooth right after recieving it. That's why I always try and ask current users about things to avoid or options to buy. I'm sure their sales guy will tell me everything (add joke

Inds, It's about time that lead-free components can stand higher temps "myth" stops. The only difference is the plating, the component itself has not changed. Can you give us an update on this threat? If you�re the same inds http://www.smtnet.com//

So, it looks like the backward compatible of BGA statement is not guarantee for solder joint reliability. It doesn�t matter what temperature and what melting sequence we have in order to avoid the solder void issue. Is Pb diffused homogeneously thr
