So as far as pb free compliance in EU there would be no residuals from pb on the pcb's to speak of. We also have deionization cabinet with chealate filter for heavy metals that recirculates the wash water.

In passives I dont know if anything changed at all other than the terminal plating. As for Active components there has been much engineering done to allow for the extra heat needed to liquify say SAC305 or other lead free pastes without damage to th

Larry has lots of experience, if you have been around the forum for a while you may remember some of his other suggestions. Now I wish I had asked the question before jumping in to Pb-free 1 1/2 years ago. We've been using the same ovens to run bot

John, there have been quite a few discussion on Mixed Assemblies in this forum.. do a search.. you will get whole lot of information.. in addition - IF you are using Lead-free reflow profile...make sure the rated temp for Sn-Pb components is not vi

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

It's possible your supplier has not thought through the results of their conversion to lead-free throughly. We'd expect something like: Reflow Parameters||Pb Assy||Pb Free Peak Temp.||235�C �5�C||255�C �5�C Time Within 5�C Peak Temp.||20 to 40 sec.|

We are running our prduction (TV's)with Lead Free Solder, since 1 year ago, but we still have a lot of Electrolityc Capacitor (Thruhole and SMT)in stock that are for PB Solder. We have to use them before February-06. Do anybody know if there is a pro

Inds, It's about time that lead-free components can stand higher temps "myth" stops. The only difference is the plating, the component itself has not changed. Can you give us an update on this threat? If you�re the same inds http://www.smtnet.com//
