Just some food for thought on various hardware failures: Tin Whiskers

post #1 of 2
Thread Starter 
As many of you know, components fail after a while. In some cases it is that a part wears out, a defect, etc. However, there is another cause for failure: Tin Whiskers.

The process and formation of whiskers is not really understood but there are certain things that seem to encourage the growth of whiskers:
  • residual stresses caused by electroplating,
  • mechanically-induced stresses,
  • stresses induced by diffusion of different metals, and
  • thermally-induced stresses

It has been linked to cause failure of satellites, nuclear control modules, and various other electronic components. Two metals primarily do this:

Zinc and Tin. This process has been also seen on other metals like Silver, Cadmium, and even Gold.

Damn cats in my machines screwing my ponents!!!!!!!!!!

On a serious note; it really can be the little things in life that matter. People sometimes wonder why certain situations require an insane degree of technical execution and handling of materials, and this is just one example of many as to why.

We don't really see it at our level of use, but to someone working on high level systems (Nuclear, Aerospace, etc), things like this can matter.
