What Is An Esd Mat

Anti static mats are grounded by being placed on top of a conductive work surface or by using grounding cables to connect them to an electrical outlet.
What is an esd mat. The ansi esd association standard used in the united states to test that an esd mat is static dissipative is ansi esd s4 1 worksurfaces resistance measurement s. The side that is blue gray or green the bottom surface is impregnated with carbon which is why it is black. Examples of these items are esd protective work station equipment trash can liners and chairs. Esd general purpose mat kits made in usa.
They are low cost durable easy to cut and are reversible. Esd mats are designed to eliminate static on its surface and of objects placed upon it. It does this by having a conductive material embedded within the mat that collects the static and sends it to ground earth. Static control esd clean room products static control grounding mats are in stock at digikey.
Antistatic mats are used under. Computer components that are sensitive to static electricity or esd are motherboards cpus expansion cards and memory devices. Anti static materials are generally referred to as any material which inhibits triboelectric charging. They include an esd general purpose mat a wrist strap and ground cord.
Static control esd clean room products ship same day. Rtt testing for esd resistance per ansi esd s4 1. This is usually accomplished by connecting the mat to ground typically the center screw of an outlet with a ground. An anti static floor mat or ground mat is an anti static device that safeguards an individual or piece of equipment like a pc from an electrostatic discharge esd.
This requires the use of a surface resistivity esd meter to perform both resistance top to top rtt and resistance to groundable point rtg tests. Insulative materials prevent or limit the flow of electrons across their surface or through their volume. These mats are made of a homogenous polymer mix. The esd protective symbol should also be used on items designed to replace static generative materials.
The top surface is static dissipative. This kind of charging is the buildup of an electric charge by the rubbing or contact with another material. This is a defined space where all surfaces objects people and esd sensitive devices esds are kept at the same electrical potential. An esd mat is a very important part of an esd protected area.
Likewise in many areas of industry plant parts can be charged electrostatically by means of friction. The item is to be esd protective or non static generative by design.
