Hello! All I am an almost smt biginner. I have a few questions My question is 1. what will be changed to use lead free solder paste in a smt production line? 2. what is the reflow profile for lead free solder paste? Don't just tell me to search th

Presumably you're talking about lead free, but you don't say. Heller can probably provide you with a starting point, as rob has already pointed out, but you do need to develop the capability to perform profiling yourself. That oven should have ECD

Doesn't the components and PCB need to be lead-free also to be a "true" lead-free process?

Sure, to be a true lead free enviroment all components need to be lead free or fall within the specifications of lead free as defined by the RoHS Directive. What I am doing is starting stage 1 of our journey. Layed out it looks some thing like this.

Thanks for the info! I have found that we see similar if not the same results. It appears that lead free processing through SMT is NO BIG DEAL. You will find that other paste Mfgrs seem to have the same performance as what you experienced.

Hi Tom, Thanks for the compliment. I've been researching and planning for the time that my company would go lead free since late in 1999. I hear you there, how do we know that the component is lead free. Baring a leap of faith with your vendors, I

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

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
