There is a way to copy the setup file as well. I've done and used them to create work instructions for the operators, but since I don't have the machine right in front of me, I don't remember exactly what file to export.

Hi Davef, Thanks for the reply. There seem to be no issues on SMT reflow based on some samples done. We have not stripped the gold yet. We did a X-section+EDX and we are seeing traces of copper on the nickel layer. Any idea what is the implication of

the answer is very simple, it comes from 12 years of experience on the mpm's. And once you've done a calibration on the programmable print head, on a AP model you will know what I mean when I say it is not the easiest thing to do. harry

Right you are. Count on it taking at least an hour if you've never done it before. I think they made the pro-head way too complicated. Standard UP style heads are so much easier.

Do you still this done? What type of rework is required? Please provide a little more info.. ksimpson@spectralresponse.com

We have the need to verify that proper intermetallic layer between a 100% Sn plated contact and the solder joint is being formed. Never having done this before: Is there any specifications, etc. that we can use as acceptability criteria?

Hi all, I have never had to run a product with BGAs on the bottomside of a double sided board. I was just wondering if this is a done thing ? or should I stay well clear. any replies appreciated. aj...

It can be done. But as Rob states, use edge rail oven. We have a product 18 inches long by 9 inches wide with BGAs on both sides.

I've done a couple fiducial transplants from populated boards to non-populated boards in the past. I've also used a soldering iron on irregular shaped HASL fids to round them out. And that is a vintage rant.

Wow, they claim 1000 cycles of -65 to 150. I wonder if this was done with the 24mm part. With those tiny joints underneath, they must have exactly matched CTE's with their test boards.
