Explanation
An ESD (Electrostatic Discharge) mat is an anti-static grounding accessory placed on a work surface. It dissipates static electricity that builds up on a technician's body or tools before it can arc into sensitive electronic components. Even a small static discharge-often undetectable by humans-can permanently damage CPUs, RAM, or motherboards. ESD mats are used alongside ESD wrist straps as part of standard electrostatic-safe work practices. They do not protect against dust (B), scratches (C), or water damage (D).
