Hi, yes, tin whiskering is a huge issue. Wikipedia has some nice (and shocking) pics on it. One of the best sources of information is the Nasa Tin Whisker page: _http://nepp.nasa.gov/whisker/_ (http://nepp.nasa.gov/whisker/) bye, Said In a message dated 9/24/2009 06:15:04 Pacific Daylight Time, [email protected] writes:
Interesting comments regarding. lead free solder. I was not aware of the tin whisker problem. We went lead free here at work several years ago. I really don't like the lead free solder we have to use on several accounts. As mentioned, you don't get nice shiny joints. They look pretty much like cold joints. We had to do some rework on some products and the lead free stuff doesn't rework well at all. We ended up having several field failures. Not good for customer relations. The processing temperatures are much higher than with eutectic and sometimes the boards come out of the oven all brown and crispy. Good thing most of what we make gets molded in plastic. I don't use lead free in the lab. One of the many reasons is to keep customers from putting engineering samples in equipment to be sold. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
