I had a link to a very good article (now gone) but here is a start. http://en.wikipedia.org/wiki/Whisker_%28metallurgy%29vickyg2003 wrote: Oh sorry to hear that you are giving up your commercial location.
In trying to understand this post, I have a couple of questions.
What is the "tin whisker" effect, what is BGA
I want to understand why the lifespan of my electronics is going to be so short.
Basically, the circuit boards will short themselves out.
BGA is a chip type. http://en.wikipedia.org/wiki/Ball_grid_array
They will eventually pop off the circuit board, cannot be repaired, but are easy to manufacture. They are the chip of choice for digital circuit design, supplied by the (usually American) Intellectual Property owners (who don't build products) to the Manufacturers (who don't own the digital design rights).
Since the offending technologies have been around in camcorders for 20 years, we have a lot of empirical data on the lifespan issue. Given the low use, low temperature case of camcorders, they were good for 7-10 years. TVs are high use, high temperature items, reducing the lifespan to about 5 years (+/-) That's why getting a full 5 year extended warranty is getting harder to find. Ending at 4 years avoids the 5 year failure crunch.
An LCD panel might last 100.000 hours but the circuit boards won't. No one makes new boards for old sets, so once they run out (18-24 months), the set is basically unrepairable. Hence the other common extended warranty period - 2 years.
