Thanks Brian,

Our bridges too, especially the Golden Gate, provides "permanent" job
security for strippers and painters as well - willing to work at such lofty
heights, in poor environmental conditions, for so long. You've given me
exactly the answer I was seeking.

Bridges are quite another matter from devices or product that can be
environmentally "shielded" to some extent. My pacemaker (don't really have
one yet) is such an example but the situation is better exemplified by
military hardware, or Class 3 product, having to meet a less critical, at
times, situations.

I'm just suggesting that if we know a cause of something, we might do more
to prevent its occurrence. If we better protect a product, until it is
required for use as an assembly for flight operations, as an example, by
better "sealing" it before it is integrated into a "sealed" system,
shouldn't we expect better life performance without serious, life
threatening possibilities as when a PCB glass fillament shorts because of a
moisture, or whatever, problem?

I'm just trying to establish that if CAF, for example, testing has revealed
it really exists, and it it's obvious it does, we should be able to prevent
it's negative consequences. If we bake, heat, solder, dry, dessicate, seal,
conformally coat, and keep dry, by whatever means, haven't we solved an
issue before it becomes a serious problem? By normal course of fabrication
and assembly, we do all these things as a "natural" matter of fact.

I believe we have discovered a major impediment to reliability and human
safety. However, it just seems to simple to prevent it from being a problem
over the life of a product.

Thanks again for your response and thanks for continuing to be,

Earl
