I just read an recent article in eetimes that the target life of new ICs
is 10 years. This is due to metal migration and other (i can't remember

to all the old gear you can get, because everything built today will be
land-fill in 10 years. I too have that microwave, stainless on the
outside for no apparent reason and a painted interior. The coating
failed after a few years.

Having been there and done that in the past,
it's not the repairability of
the sets, its the economics of running a service business and the amount of
money that you need to charge to stay in business vs. the cost of simply
replacing it with a new one. _That_ is what killed it for me...
Roy, one thing occurred to me. What is the current service life
designed for by the major manufacturers? I ask because of a recent
episode with a microwave oven.
We replaced a microwave oven that dated from about 1980 with a newer
one about 4 years ago. The big difference (both were Japanese
brands) is that the oven box in the old one looked to be a very tough
porcelain enamel--almost impossible to scratch. In the newer model,
the coating was a simple baked-on epoxy enamel paint that failed in
less than 2 years. After recoating it a couple of times with ratttle-
can epoxy, I gave up and purchased a new one with a stainless steel
interior. But the oven itself is much lighter and I suspect that the
electronics will not have 20 years of life in them.
Is a shorter service life by design a feature of modern consumer
electronics (and in particular, computer gear)appliances and
automobiles?
Cheers,
Chuck
