This application is military, which requires a minimum of 3% Pb on the terminations, or mulitple mitigations for tin whisker prevention.

Chris, WEEE is great but RoHS doesn�t make since, here�s a couple of threads covering similar issues. http://www.smtnet.com//forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=10341&#Message41486 http://www.smtnet.com//forums/index.cfm?fuse

Everyone has been playing a guess game so far :-) but we don't even know what the lead finish is:-) Even old (Sn-Pb finish) days, the ammount of Pb in the plating would be on a single digit level (just to mitigate Sn-whiskers growth), meaning that th

Well, typical content of Pb in Sn/Pb polating is a few percent (just to mitigate Sn whiskers growth). Therefore, the lead finished with SAC305 won't be much different from those finished with Sn/Pb. You can make one or two cross-sections for sanity c

Darby, To my knowledge no case of RoHS (lead) violation has ever gone to court in the EU. The only documented RoHS (lead) violation (again that I�m aware of) has been settled out of court in the UK. Check here: http://www.eetimes.com/news/latest/s

thank you devef....My point is this....If you solder all the areas that have Imm Sn on them, there wont be any whisker formation DUE TO THE IMM TIN COATING.....whiskers could still potentially form as a result of COMPONENT FINISHES and effective miti

This is a post from another forum as a response from Bob Landman to a claim that he had no evidence to be concerned about lead-free in hirel applications (interesting read). See below and am sure many technetters will find this interesting **********

Keep in mind that you may need to assure that there are no pure tin finishes remaining on your parts. A general idea is that parts with pure tin (RoHs) finish will need to be plated with tin-lead solder to avoid the possibility of tin whiskers formi
