Usually the microprocessors last forever - it's the thrystors or
triacs
driving the load that go pop.
Not even close ...
Really ? Look at the standard SEMI MTBF charts then.
When you spend your days repairing boiler PCBs, you don't need to look
at charts to tell you the faults.
as I said .. in the real world
So what parts do you find die most often ? And is the information fed
back
to the manufacturers to stop them carrying on using a faulty design ?
You are joking, I take it
Of course they know the design faults
If they do and have an ISO9001 certificate then report them !!
Do I look stupid ?
(rhetorical question,, that)
