Hi Andy,

Thanks for your inputs.

"That's called Functional Test - nothing to do with Burn-In."

Accepted. Maybe Burn-In is an oxymoron as you mentioned when done at room temperatures. But still an infinite loop through the code, if planned properly, can stress out all the components in the power chain and bring out that odd one which died prematurely.

"As Erik said, they're not faults, they're a Design Flaws"

Maybe I worded it wrong. One of the problems that we face here is due to poor vendor support on accessories. Heat sink pastes are nothing but chalk powder, transformer cores are just MildSteel sheets - the list is endless. Thus even with the best of design we have had surprise failures due to above. Thus such kind of functional tests for an extended period bring out such black sheeps - that are eventually blacklisted.

"The purpose of Running-In is to allow parts to bed-in, by giving them a period of gentle operation - quite the opposite of Burn-In! This is applied to mechanical moving parts"

I like it. Worded well.

Have a nice day.
