The purpose of an ESD protective working surface is to aid in the prevention of damage to ESD sensitive items (ESDS) and assemblies from electrostatic discharge. ESD mats need to be grounded. A ground wire from the mat should connect to the common point ground which is connected to ground, preferably equipment ground. For electronics manufacturing a worksurface resistance to ground (Rg) of 1 x 104 to less than 1 x 109 ohms is recommended. Best practice is that ground connections use firm fitting connecting devices such as metallic crimps, snaps and banana plugs to connect to designated ground points. The use of alligator clips is not recommended. Find accessories here.
To ensure the continuing safety of people and ESD-sensitive electronics, all static-controlled workstations should be periodically tested for ground integrity. See our resistance tester section
for more details.
For optimum electrical performance, surfaces must be cleaned regularly using an ESD mat cleaner. Vermason suggests using our Reztore™ Surface & Mat Cleaner
. Do not use cleaners with silicone. Silicone buildup will create an insulative film on the surface.
Vermason's EVA Bench Matting and Shelf Lining is flexible, tough and fairly hard. It is made of a modified polyethylene and offers excellent chemical resistance. Its surface is smooth and is easily wiped down. Conductive EVA is a very good, low-cost shelf covering material. It is also used to cover ESD benches where spillage of potting or cleaning chemicals can occur. However, its heat resistance is comparatively low and it should not be used at solder stations.
