Tin whiskers are real and can cause serious problems. That's why NASA maintains a web page on the issue. [ http://nepp.nasa.gov/whisker/ ] and why space flight is is exempt from Euroland lead-free requirements.

I have heard there is a process for mitigating the pure tin issues for 0402/0201 size parts by the use of SN63/PB37 solder print process. Is this true and does anyone have the data to back this up?

Some of us here attended the 5th CALCE international symposium on tin whiskers http://www.calce.umd.edu/symposiums/ISTW2011.htm where one of my former professors, Dr. Henning Leidecker, talked about the tin whiskers he and the others at NASA Godda

Are you sure it was a whisker and not a peace of paperclip??

do you intend to use Immersion tin as a PCB surface finish ? Then Whisker concern is as below if you do not past your test pads, the pads will be stressed when probed on a ICT or a flying probe tester. This is a POTENTIAL for whiskers There is a lo

1)What is the difference between Bright and Matte Tin? 2)How do you perform Tin Whisker Test?

OK, I feel the need to jump in here. Bright Tin has the tendency to easily whisker, and is almost never used, except on some through-hole connectors, I believe. Matte Tin is much less susceptible to whiskering, although under the right stress cond

during my researches for LF transition, a question being asked is -- why even consider immersion tin if it whiskers. does it really matter?, because during reflow, the Sn dissolves in the SAC solder alloy and does not exist in a "Sn whisker" formabl

What is the most popular PCB finish for lead-free soldering ? We are using ENIG and trying out Paladium-Silver. Are tin whiskers an issue for anyone ? tin whiskering becomes a big issue if you have any military company as your client. They still p

Hi, I have a very basic question for tin whisker testing. Do I thermal cycle/age the Components only or solder them to a ckt board and then thermal cycle/age the PCB assembly??
