Chris, I suggest you might like to subscribe to the IPC "leadfree" email forum which is devoted to RoHS and WEEE issues. There are searchable archives.
http://www.ipc.org/contentpage.asp?PageID=4.3.1 Also see the UK NPL website for good info on Pb-F reliability. Regards, Chris From: [email protected] [mailto:[email protected]] On Behalf Of Chileshe, Chris Sent: 13 January 2006 15:12 To: [email protected] Subject: RE: Off-topic: lead free solder and reliability Jim, This is a very interesting topic. I am in the process of migrating the first of our products to lead-free and your e-mail and John's reply made me pause (complete with alarmed look!) for thought. Reliability of Pb-free solder was brought into question here on the list about a year ago - possibly longer. I have come to believe - possibly through misinformation - that most of the problems were the "teething" sort (early days) and that now the process was understood, there were no more major problems with Pb-free solders and processes. I followed some links from John's e-mail and I am beginning to worry about Pb-free. Please keep this thread going. Rgds - Chris Chileshe O.O.Only From: [email protected] [mailto:[email protected]]On Behalf Of Jim Eichner Sent: 12 January 2006 00:19 To: [email protected] Subject: Off-topic: lead free solder and reliability Can anyone can point me to any reliability studies done on lead-free soldering? I'm not looking for "how to" information but for studies that assume it's done right and then evaluate the reliability impact (if any)? For example, lead-free solders are harder and more brittle, so reliability in the face of vibration is lower compared to conventional lead solder, even if the process is optimized.
