Hi I just would like to ask some assistance how to convert a line using a leaded process to a lead-free process? Is there a need for us to change any equipment? printer/reflow? Currently, we are not yet in full 100% lead-free process yet so most lik

HI, I actually have ask the same question a while back. Yes, using lead free component in a leaded process should be no problem at all. May required just a little hotter peak temp. during reflow, to achive optimal solderability.

Could you advise what is the min and max peak temperature for this process. Presently, my leaded peak temperature at the range of 215 - 225 deg.C And how do I know that the solderability is at optimal. Appreciate your help......

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?

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

Is your oven suitable for Lead free temperatures & can it achieve a decent profile across your complete range of boards? AOI will need to be looked at too as the joints are not as shiney. Cheers, Rob. PS. Where's Thisbie?

Ya Russ is right for Ti Parts they tend to use more pelladium, which requires a bit more heat average temp increase is about 10 degrees C. from 225-235. As far as optimum solder joint I look for fillets on all sides of leads. The back of the lead is

Ed: We agree with you that leadfree parts can be used with leaded paste. We disagree that lead part can be used with leadfree paste. Here is link to a previous discussion here on SMTnet on the topic: http://www.smtnet.com/forums/Index.cfm?CFApp=1&M

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

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
