I agree with what those other guys said. You problem description is vague. Please describe: * 'Broken' trace appearance * Where it is located * Process steps up to discovery * Board design * etc.

If you're in the US you can get the Fuji stuff from FAC at (847)913-0162 ask for Patti in training, I believe she still does the manuals.

It's been quite a few ywars since I dealt with Panasonics but you might try Panasonic factory automation. I believe they are in Elgin, Illinois now. You might try their website I believe the URL is http://www.panasonicfa.com

The residues are from the flux, not adhesive. Do you have flux management system in oven? You also need to check the flux type = can you use low solids. The effect is the same as steam in bathroom - it is cooling affects in exhaust and flux reforming

I hated no-clean for that reason. Yea, the boards are pretty clean and in many cases don't need cleaning but it's not worth it when you consider what it does to your ovens in my opinion. Do water soluable fluxes cause the same havoc in a re-flow?

Thanks for the replys'. So are you saying that SMD adhesive contains a flux agent?, because at this point in the process the boards have no solder on them at all, it's all done at a solder bath after the chips have been bonded.

no, the oven is only used for curing adhesive and has never been used for reflow!!. I have always assumed that it has been the solvents in the glue that have evaporated off and then cooled again.

Wow. We've never seen that. You make a reasonable assumption. Since your PD944 is fairly widely used, what does Heraeus say?
