And another thing they do is repacking parts that were rejected in
productionlines. Many parts ar made in Asia, the scrap is sent to
certain companies specialized in scrapping. But they just repack them
and sell them as new. Notice that these are rejected and potentially
(in medical equipment etc) dangerous parts!

And what they do too is remarking. They take normal processors and
make a military one of it by remarking them. On your testbench they
will test ok. But at for example extreme temperatures they will fail.
Would you like to be in an airplane controlled by such parts?


Not sure about Medical; But the MOD and Aviation industries
have strict procedure. Every part can be directly related
back to its point of manufacture - thats why Mil-Spec is so
bloody expensive, I can see it would be tempting financially
for a suppler to trade non-authentic or copy parts but it
would be difficult to reproduce the required history for
such a part to be able to supply it in the first place.

In Aviation every part is in its own bag with a specific
number that points to a huge paperwork trail and when its
fitted to a piece of equipment the paperwork is then
included within the aircraft manual, its not unusual for a
singular aircraft to gave several filing cabinets of
history. I've worked on aircraft communications equipment,
it can 10 minutes to fix the equipment and then another hour
to fill in the paperwork. No Certificated engineer is going
to risk his qualification fitting a part he cannot
substantiate as being authentic with the relevant paperwork,
it just too expensive and takes too long to get the
accreditation in the first place to risk it for a few pounds.
