Almost forgot about the Metcal soldering irons.   The ones that heat
up quickly using RF.  We had a problem with one of these at work
a few years ago when the shield at the connector came slightly loose.

What happened was that there was a lot of RF leaking from the iron
tip to the circuit being soldered and it broke LOTS of 74HC14 parts.
It was not always immediataley apparent that they were bad until
later.

So I guess you gotta make sure the connections are tight on those
types of irons.

Thanks for that. I use Metcal equipment, it's quite cheap bought second-hand 
on eBay. I just checked the connector on mine and it was slightly loose - 
only needed part of a turn. I don't think I've checked it since I first 
assembled it a couple of years ago.
