I had a similar problem with a very low power surface mount board. All
resistor were very high high values. We were actually getting silver
migration from the end of the surface mount components -  especially
capacitors - that had a steady dc voltage applied. Under a microscope it
looked like frost on a window.

Hi,

 We were getting quite a few shorts on our caps and boards due to tin
 whiskers.
 we resolved the problem by conformal coating. Just wondering if anyone
 else has
 this problem and how did you solve it?

 Thanks in advance.
