Hey folks, I was interested in any information that you might have on tombstone reduction when using a lead free solder and profile. Thanks for any input that you may have! -Russ #x

It does. I looked into the Cookson/P.C. kit, and it looks like a good deal. So, I'll go with that. (We're already running Pb free, but we'd like solid hard data for customers) Thanks all.

Yeah, that's what I'm doing now. I have it now peaking around 235, with about 70 sec. above 220C. (220C is the reflow temp, according to manufacturer. I've always used 217C for Pb free) Wish me luck. Thanks!

Dave: The main part of your machine that VOC-Free fluxes attack is your spray fluxer itself. If you haven't already, you'll need to purchase a spray fluxer that's designed to accomodate water-based VOC-Free fluxes (i.e. made of stainless steel with

Jay, Yes, we did assigned new part numbers for our lead free components. Our concern was how do we know that this component is lead free. New part numbers was our only way. It made the component engineers cry, but offer them a box of Krispy Kreames

Hi Jay, Concerning you PCB, what TG do you expect to use for your lead free process? On my side I have a problem. I order PCB from Canada and from China. My PCB vendor in china is producing a lot of OSP and ENIG PCB, no HASL lead free and in Cana

Glenn, i am aware of one unique problem with voc free fluxes. since these fluxes have certain amountb of water content they cause sputtering leading to solder balls & voids problems. Regards Vinesh Gandhi | I require some feed back from any one

We all know the Lead Free process is trend, so we trial run it, now it is only my comment that we have a good achievement after several tries,we have taken serveral photos about Lead Free process with ErsaScope. 1.The surface of the solder joint are
