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

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

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?

My policy is not to mix them. You have zero cross contamination potiental with this policy.

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.

I don't think that you would need to test these. Have you ever seen any evidence of solder sticking to them? We use the same material and never notice anything besides flux staying on the bottom. Would the lead absorption if any even be of a concer

I agree with Chris. Not all but SOME components definitely had to change to be able to withstand higher heat. I would watch out for some plastic connectors, possibly some active components, and definitely many electrolytic caps. Older stock compone
