We believe imm tin suppliers say that their product does not whiskey, oops whisker, because they use 'white tin' not the 'gray tin' that causes whiskers. But as soon as you alloy their tin with SAC or any other high tin content solder, all bets are

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

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

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

looks like everyone is in dark on this one......and i thought it would be pretty intuitive

Interesting observation Manuel. I will be blamed again for crying wolf but look below a lot more defects will soon see the daylight all related to lead-free. This information was posted at the tin whisker forum by Bob Landman of H&L Instruments.

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