As we recall, they attached something like a placement vib head to the rails. The problem, as you stated, was isolating the board from the vibrating rails during cooling of the solder connection.

Look to the no-Pb solderpaste mfr. specs for on-board temps. For example, Indium Corp. has a product that performs at on-board temps of 229C. Now, your BTU oven will handle this no problem, as will most modern ovens. Its all about thermal mass. Look

Agree with WiIIR and also can recommend to play with vaccum pump RPM . Slower vacuum increasing have help me to resolve one problem caused by the vacuum (it was solder splash from BGA balls, but the reason can be similar to your case). Also check i

I can guarantee that vibrating ovens will be detrimental in double sided reflow for any of the larger parts. I find it interesting about BTU and there "vibrating" oven. I had a couple of these in the early days and they did indeed vibrate. However

We are in the process of launching a new product and found reflow solder issue with one of the inductors. I have set oven profile to paste specifications. I just finished profiling with thermocouple under problem component. All other components ex

BTU as well as most oven manufactuers have great products. If they fit what your looking for and can give you good support(preferably local) then you should not really see any quality problems with their products. With the oven max temperature of 300

Hi J, Yes, we do too. Funny thing is I was just looking at this last Friday. We call it sharing the bottom of the barrel. Typically it's just Process Engineers stuck down here, but from time to time, Maintenance gets stuck down here too. When in

Have you profiled at the problem side of the part?

Thanks AJ, It is looking like a CTE issue.
