Agreed

You are even getting close to the 30 years life expectancy of semiconductors!

interesting, what's your source ?

Standard industry knowledge really, still taught to students so I assume still valid. Google for semiconductor bathtub or follow links from wiki :

http://en.wikipedia.org/wiki/Bathtub_curve

 

Failures drop drastically in the first few months due to defects then rise fairly quickly around the 30 year mark due to diffusion and other wear out processes, leaving probability of failure looking like a section through a bath tub. Higher temperatures lead to earlier failures. Some components like DRAM have very much lower life span, and things like IGBT power devices are expected to live longer.

Can tell you're not an installer

just wanted a nice simple link....

i have 2 Sinclair C5's - 30 years old and still going strong lol!

Not cars are they
