SMPS Sub-circuit is faulty

Report the issue to his boss, or however far up the chain he feels comfortable. Make the report via email or other recordable media (for instance, if Whatsap then save the conversation offline). Job done, forget about it until and unless responsible people want more details.

Brownie points for writing an actual report detailing the issue and possible solutions. Won't make any difference but creates a much larger cover for his arse and, of course, there will be a larger record.

With respect to those who have taken the time to respond to this thread I apologise for my comments, but this is the biggest load of bullshit I've read in a while.

I fear you haven't had the pleasure of reading treFaringdon's posts for very long, or you'd realise how innocuous this is, relatively.  ;)

Which bit is bullshit? while Farringdon does seem to bring some unique, erm, "perspectives" to the forum I have been told to shut up in the past, the attitude was see no evil, hear no evil speak no evil. And the stuff was literally life support.

--- Quote from: Faringdon on June 10, 2023, 11:35:52 am ---My friend examined the sub-circuit, and noticed that it had  a very serious fault, and that in fact, this sub-circuit would simply not work…..under certain circumstances, this sub-circuit may result in serious product failure.

Of course, My friend cannot be absolutely completely certain that this faulty circuitry actually exists in currently operational miltary power supplies…..but is worried in case it does. He just gets stone-walled whenever he asks about it.

What exactly was this serious fault?

If you can't for security/privacy reasons tell us, the exact specifics, can you describe it in general terms?

If it had this serious technical design fault, and it simply would NOT work under any circumstances.

Then how on earth did it get through, both all of your friend's companies testing and validation programmes.  All your friend's customer testing and validation programmes.

Then finally work as the final product, without failing dramatically?

It is all too easy to THINK that a serious design mistake has been spotted, but it is all too easy, to be mistaken.
