Hello
Do somebody know where quality -specifications for products (PCBA and
electronic units) for the automotive industry could be found.
Are there any common documents?
Or are there somewhere documents from big companies?
Greetings
Siggi

Subject: Re: [TN] Tin whiskers
My understanding is that the matte tin finishes do not eliminate tin
whisker. Some argue that the finish reduces the length of the whiskers that
are likely to form. I wish I had ready access to the presentations that I
have seen on this subject. Let's see where this thread goes.

Subject: [TN] Tin whiskers
After storage of about 6 months we saw Tin whiskers inside
the hole barrel on Immersion Tin plated boards. It is the second time we
found them, and the batches were from two different suppliers.
According to our knowledge, they they are using the
immersion tin technologies which are said to prevent whisker formation when
applied properly.
What can be the cause?
