It would appear that pure tin is backward compatible with leaded processes. This makes it a great finish, as if you migrate all your parts over time there is no issue mixing them. I am not aware of any finish that eliminates the possibility of tin wh

Hi Samir can you post some pictures of the whiskers ? I would also recomend you post your pictures on the IPC listserve forum for lead-free where you will find a focussed group that will be very interested in your pictures. http://listserv.ipc.or

http://www.techeye.net/chips/electronic-tin-whiskers-may-be-behind-toyota-recalls This article doesn't mention that their source is speculative and poorly written. But I am curious has Toyota confirmed that they do use tin/lead solder? I mean an ex

Most component fabricators don't properly understand the impact of soldering with pure tin solderability protection on components. Here's one that does: "The Effects of Board Attachment Processing on Sn Whisker Formation on Electroplated Matte-Sn on

This is absolutely true. We have spent more than 10.000 man hrs on this, investigating of a fail safe interconnection that need to last more than 50 years in extremely harsh conditions. Tin Whiskers was at our "ten most wanted" list to be solved. Ba

Its it possible to post a picture from right after reflow? To see what we start with and compare the difference after 5 years. The grainy structure is not as much a concern as the growth-like appearance on the boundary of the solder. What paste al

Steve, Let me try to give you a short answer to your question. A good book in soft soldering would talk about the excellent characteristics of leaded alloys and all the reasons why leaded alloys are very reliable. In short a good book would advice y

Although DaveF's answer was probably more applicable and there is some really good info on Tin Whiskers it doesn�t really answer the question either from what I saw. I suspect this will become a much larger issue as we all are weaned off of lead!

I think 10% of us already knew this. I saw the boomerang coming years ago when LF was first mentioned. Did you guys see the tin whisker mention on the History Channel last night? It was on Technological Disasters (I believe). Didn�t see WML, bu

It really doesn't matter that military has an exemption. They're still stuck with the same tin whisker risk since the component manufacturers have switched to service the consumer electronics market which are their large volume customers. The same i
