Assembly mat

[Ken817821]

I am thinking I will get some aluminum sided insulation that  you see in rolls at Lowes and use it as an assembly mat.  Then one can not help but be frequently touching the mat in the process or assembly.  Maybe also have a piece on the floor that you are standing on that is connected to the work mat.

The normal anti-static mat has a high resistance per square. An
aluminum mat will have a very low resistance.

How much damage is done to a powered up board when it is placed the
aluminum mat? Keep in mind that boards that have a battery or a
super-cap are powered up. Boards with real-time-clocks are powered up.
Boards that have non-volatile memory might be powered up.


I'll let someone else address the people safety issue.

When you set a PC board down on it, a spark can jump from the board to
the aluminum, zapping some sensitive part in the process.  You need a
high resistance path so the static can bleed off more gradually.

I have heard of people using moistened newspaper as an anti-static mat.
Seems like it would work, but I never tried it because it seems too
uncontrolled.
