In semiconductor fabs, SMT assembly lines, and electronics manufacturing, electrostatic discharge (ESD) is a silent component killer. Everyday friction from component trays, tools, or handling can easily build up thousands of volts of static charge. Standard workbench surfaces pose extreme hazards: Insulating Plastics: Hold static charges, causing sudden high-voltage sparks that fry chip micro-circuits. Pure […]
