ESD (Electrostatic Discharge) is static electricity. ESD occurs when touching an object that conducts static electricity. ESD can damage memory modules.
To protect your memory module from ESD, always store components in antistatic packaging until use. Before handling memory modules we recommend you discharge any static by touching an earthed metal object such as a nearby unpainted radiator or pipe.
ESD wrist straps can be purchased to provide additional ESD protection.
