Arcade machines require robust electrostatic discharge (ESD) protection to prevent damage to sensitive electronic components. The most common protection types include proper grounding through metal chassis and conductive flooring, which directs static electricity away from circuits. Transient Voltage Suppression (TVS) diodes are frequently installed across power rails and I/O ports to clamp voltage spikes. Many arcade PCBs incorporate spark gaps and series resistors on input lines to dissipate ESD energy. Conductive foam and shielding bags protect unused PCBs during storage. Additionally, ESD-resistant materials in control panels and coin mechanisms help prevent static buildup from user interaction. Regular maintenance ensures these protections remain effective throughout the machine's operational life.
