[Elecraft] Static

[Don Wilhelm]

Kieth,

I agree with all your ESD comments, but I would hesitate to suggest that
anyone do electronics work on a completely conductive surface such as a
sheet of aluminum.  The possibility of a short to the work surface while
testing or working on powered equipment is high.  Even with low voltages,
the current can be high and therefore dangerous.  The surface should be
conductive, but not of a low resistance.

Anti-static mats are available that are the size of a computer keyboard and
these work fine - it is what I use, and it was not expensive (comparable to
the price of a sheet of aluminum).  The larger anti-static mats intended for
full workbench coverage are quite pricy for hobbists.  Google on 'keyboard
mat' to find several sources at a reasonable price.

73,
Don W3FPR
