Haven't run those boards again, so haven't had the issue.. Since it seems like we may want to start using more aggressive flux based paste soon, what are some good choices? Ideally I'd like to stay with Kester, since they are readily available. EP2

We have been experiencing an issue with solder balls coming out of wave, both RoHS and 63/37, no clean process. It has been determined that a reduction in flux has all but eliminated the solder balls except for where we need to use board stiffeners a

Hi Evtimov, Thanks again! The solder wicking/open solder joint is not actually gross rejection, it is only a few and appeared random (difficult to trend the location of the opens), what is perflexing is that i have this 1 or 2 open solder joints sur

A few lifetimes ago I went to a seminar on reflow profiles. The speaker emphasized more than once that the cool down rate is important. Someone asked him about controlling the cool down rate and he acknowledged that you can't. And IIRC it was an ove

There are two areas that are important when discussing cooling rate. One is the rate thru the liquidus, where a fast rate produces small grains in the metal and a slow rate results in larger grains. Although smaller grains are stronger normal SM

I am assuming you are initializing each motor individually through the service program. The z motor theta is hard to see so I put a mark on it with a colored marker so you can watch if the midas tool nozzle is actually turning or not. You should be a

I work with small batches and this is what I do. However I don't do it because of the paste. Instead I do it because I am the sole operator on the line and I want one process finished so I can keep a better eye on the others. I specifically work with
