Can you implement a longer soak? how many feet of heat do you have in oven? Russ

What the hell our you talking about 200 c max? I would think any nolead part is capable of going hi-er that this. I think you are looking at max temps or something that does not make sents for temps you need to reflow.

My board reaches 240 C for 45 seconds. Most of my lead free parts require 230 C for a minimum of 30 seconds.

Sure! But they warm up slower than everything else, so it's not a big deal. You can taylor your profile around them and never exceed your 50 second threshold.

A tenative yes. The hesitance comes because it seems that you're setting us up for something. So, howbout you tell us just what's going on?

Thanks for the resources. I plan on contacting them to get some answers. I hope this all works out for us & can help others someday should they come accross similar issues too. Thanks again.

The last time I got corroded parts out of my wash was when my DI tanks were spent, and I was pretty much using straight tap water. Refreshing the DI tanks eliminated my issue. Hope this helps. cheers, ..rob
