Kris, this practice has gone on for years. I have never heard of any problems associated with this. I have heard "grumblings" about tin lead parts being processed with lead free paste, but have seen or heard of no data to support. Russ

Hi Any body have any issues soldering tin lead solder paste with lead free terminations ? Components are leaded devices and chip components have read the theoritical discussions on the forum, need to know if any body has seen any real issues tod

To take our turn at keeping everyone else on the straight and narrow. For more on lead contamination of no-lead solder, look here: http://www.aimsolder.com/techarticles/Lead%20Contamination%20in%20Lead-Free%20Electronics%20Assembly.pdf [We apolog

I have experienced this directly in SMT and wave solder. Fillet lift (can) be a direct indicator to lead enrichment (but its not the exclusive symptom). Lead enrichment in smt joints reduces the interfacial strength shortening the time to creep f

NO-LEAD COMPONENTS WITH LEAD SOLDER ISSUE: We agree with Russ. We've dicussed this several times on SMTnet. For instance, look here http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=25394 LEAD COMPONENTS WITH NO-LEAD SOLDER ISSUE: We disa

Now see Dave, now I have some good info on why it is "bad", This must be the lead enrichment I have heard about but never got any substantiated data or explanantion. I wonder how much weaker or less reliable these are. Is there any data that you k

Regarding Lead Free component finishes, vendors are zeroing in on matte tin plating as the finish of choice. What test are performed, to determine if a finish is "matte" type (vs. non-matte)?

I just hope that lead-free alloys will only be used in tropical climates and above 13 C. Check here: http://materials.open.ac.uk/srg/srg_tp.htm Patrick
