I consider them a personal challenge set to me by the manufacturer.

Like the pair of "one size fits all" pants, that ripped after only 4
people!

Or the bomb-proof trash containers that the local government buys, that
are supposed to contain a stick of dynamite exploding. Now THAT sounds
like a dare to me!

A rep from Semikron once proudly announced their new "rupture proof"
IGBT modules. We got one, attached it to a PCB with 6.6mF bus caps,
shorted the other device, cranked it up to 900V and turned it on. The
package didnt rupture but the assembly leaped 12" or so into the air.

So we did it again, but sat an anvil on top of the PCB. BLAMMO, it
destroyed itself completely, spraying "japanese snot" (we used Fuji
IGBTs for many years hence the term) everywhere. The rep was suitably
embarassed, and somewhat scared :)

900V? Was the IGBT rated for that voltage?

:)

Reminds me of those "fireproof" safes... sure, put a thermonuclear
device in one of dem dare fireproof safes, and we'll see who's
fireproof...
