[mdlug] Conductive Tabletop Mats Vs ESD Mats Recommendations Please?

[Jeff Hanson]

You could make your own caps, maybe with heat shrink tubing.  For ESD
control you can increase humidity above 50% or just touch any grounded
metal component before touching the laptop or dock.  I have a metal
frame desk and I grounded the frame to a grounded duplex power
receptacle and make it a point to touch it before I use my laptop.

Any cheap ESD mat will function but the differences are in the
quality.  The better ones last longer and are resistant to burns from
soldering equipment.  A grounded static-conductive (silvery) ESD bag
would work.  Most motherboards ship with large ones.  You could also
use aluminum foil or a thin aluminum plate.  You shouldn't need a
floor mat.
