I would recommend you take a look at JBC if you are looking for a "good" soldering iron to work with lead free solder. Find the attached comparative graphs and before anybody asks. Yes, I am affiliated with JBC.

I'm not affiliated with JBC in any way, but I do agree you should take a look at them.

You should set the temperature at liquidus point of the solder used on the BGA plus 20 to 25*C. So, for tin-lead that would be ~215*C. Most lead-free solders run about ~20 to 25*C higher than that.

"Good morning gentlemen" Oh my. I may have to pull up a chair with some popcorn for this one.

Does your top-side preheat NEED to be that high, and so high that you are exceeding the flux manufacturers' spec? If so, what is the reason? Top-side wetting? Are you measuring this temperature at the substrate or solder joint?

I'm not b*tchy. You "guys" are too sensitive. I took my HR training and now know how fragile you "guys" all are. It's not your fault, it was my fault and I learned to deal with it. Go pop some popcorn.

Your best bet is do your homework and read all the material about lead-free. IPC home page is your best site to visit.

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.
