Dave, For lead free, I've always left the ramp part the same and just spike higher in the reflow zone. I've also slowed things down a bit (5" per sec. slower)....without using prediction software, try, say... Z4 200 & Z5 260.

What part of the U.S. are you located? You can save quite a bit on shipping charges. Petlock always seem to have some in stock. If your in the midwest I can direct you to one I have purchased equipment from in the past. G

While you're waiting, consider giving your paste manufacturer a call. They should have a database of recommended, or starting point profiles based on what oven you have. cheers, ..rob

This VIP70 has thermocouple inputs, so I'm hoping that's a good enough profiler. I tried a fairly different profile than you mentioned, so will test your settings today as well. If anyone has opinions, please jump in. Thanks!

That's very helpful, and much appreciated. I know it's a long shot, but I don't suppose you know what paste they are using with these settings. I am testing with sn100c ws488. Thanks! kinos

We are not having any real issues. I am just first setting up a lead free profile, and was looking for a starting place. So far it's going well. Can you tell me more about why your paste would be better and I'll pass that on to the decision makers?
