A recommended anti-static mat is the Minnesota Mining and Manufacturing Company (3M)
Part Number 8210. This mat is 0.6 m x 1.2 m (2 ft. x 4 ft.), and has an isolation resistor in
series with the ground wire of between 10
6
ohm; and 10
9
ohm. A smaller mat may be used on
site.
In addition to the table mat, person dissembling the system should either:
• Wear a conductive wrist strap (3M Part No. 2046) attached to the mat by the 1.2 m (4 ft.)
wire included with the strap, or
• Stand on a floor mat with leather-soled shoes. The floor mat (3M Part No. 8200) also has an
isolation resistor in series with its ground lead for personnel protection.
When transporting circuit board assemblies, always place them in their shipping containers.
To protect CMOS integrated circuits (ICs), never transport them ORRVH or they may be
damaged from static discharge, or their pins damaged or misaligned.
