An electrostatic-sensitive device (often abbreviated ESD) is any component (primarily electrical) which can be damaged by common static charges which build up on people, tools, and other non-conductors or semiconductors. ESD commonly also stands for electrostatic discharge.
As electronic parts like computer central processing units (CPUs) become packed more and more densely with transistors the transistors shrink and become more and more vulnerable to ESD.
Common electrostatic-sensitive devices include:
ESD-safe working
Often an ESD-safe foam or ESD-safe bag are required for transporting such components. When working with them, a technician will often use a grounding mat or other grounding tool to keep from damaging the equipment. A technician may also wear antistatic garments or an antistatic wrist strap
There are several kinds of ESD protective materials:
