This can be very serious. I have had to replace a couple of soldering iron
power supplies for this reason. The worst case was a 60V leakage. We found
this because one of our operators was working at a conductive surface.
Figured something was wrong when she fell out of her chair. Didn't do much
good for the board she was working on either, destroyed a $600 part.

Subject: [TN] iron tip potential


Dear all, hello

My question about the potential deference between the soldering iron tip and
the ESD grounded mat. I observed that it is about 20 to 30 volts, is it safe
for ESD sensitive device? and is it mandatory to keep the iron tip on same
potential with ESD grounded mat.
