Subject:New Product Burn-In (was NUMA, et. al.)

Totally agree with you Gary, from a fellow electronics engineer. Although
burn-in is impractical for companies to do on a routine basis, it is NOT
impractical for individuals to do on ANY new electronics they buy. I was told,
or somehow led to believe, that new electronics that might fail, will do so
within the first 200 hours of operation. And the terrible title "Infant
Mortality" is given to that principle. So I suggest to many to just leave the
new electronics on for 9 or 10 days, 24-hours per day. Since many things are
sold with at least a 30-day warranty, that would mean an average of 6 to 7 hours
per day for the first month.

Maybe someone out there has more up-to-date data on the number of hours. If so,
please let me know.

Lou

Subject: RE: [CWSG] NUMA (or whatever) - should you wait to buy?

I have been an electronics engineer for (way too ) many years now and to matter
how much testing you do
electronics can fail. QC certainly helps minimize the occurrence but it still
happens. Actually burn-in time is
a great way to separate out the failures as electronics are more likely to fail
earlier in life than later. This is
however impractical for a company that is trying to get units out the door so
their ROI time is shorter.
