I took a Lead Free troubleshooting Class at SMTA in Chicago last September taught by Phil Zarrow. He told us during that seminar that its not a good practice to cross contaminate Leaded and Lead Free components but IF it is necesary than using lead

Yes you can use no-lead parts in a leaded process. Your solder joints will be weaker than they once were unless you change your solder paste. You can try to improve this by running a hotter reflow temp, but be careful since your flux was not design

Hello All. Can the experts in the lead free field guide me to the articles / data confirming that it is OK to use lead free components in the normal "leaded" (Pb) SMT process. And also if any changes in the process would be required to be made. Th

Yes, you can use lead-free parts in a leaded process. And the other is true as well, no-lead free parts in a leaded process. BUT, you should not use leaded parts through a non-lead wave solder process and of course, your board will not be RoSH.

Thanks guys for the suggestions. But, what I am looking for is data, papers, articles to support this process of using lead free parts in leaded process. Again thanks for any help that you can provide.

Chris, To my knowledge the only difference between leaded and lead-free components is the termination plating. What has changed in the component design that makes them resistant to higher temperatures?

Amen to that Hussman. The new lead-free world is not based on science or environment it�s all about $$$$$. And as I said before the promoters of lead-free care less about quality or reliability they just take this great opportunity to double their

While you're waiting for others to respond, search the fine SMTnet Archives.

For the lead free reflow process we tested with our Vitronics 500smr oven. To reach the high temperature of the lead free profile was no problem. We are not using an active cooling system so the pcb's are maby to hot wen the leaving the oven. Can an
