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 Micastat® Dissipative Laminate is a dissipative high pressure thermoset amino resin laminate. It provides a reliable path to ground and eliminates static charge generation when used as a worksurface. Micastat® Dissipative Laminate meets EN 61340-5-1 working surface required limit for contact with ESD susceptible items. The dedicated conductive layer allows the laminate to be used with ESD continuous monitors. The sheets can be laminated to wooden tables or bench tops with conventional contact adhesive.
