Arcade PCBs (Printed Circuit Boards) are highly susceptible to Electrostatic Discharge (ESD), which can cause permanent damage to sensitive components. To mitigate this risk, several ESD protection methods are commonly employed:

1. TVS Diodes (Transient Voltage Suppressors): These components clamp excessive voltage spikes and divert ESD energy away from critical circuits, ensuring quick response times and high reliability.

2. ESD Suppressors: Specialized devices designed to absorb and dissipate ESD energy before it reaches sensitive parts. They are often integrated into connectors or signal lines.

3. PCB Shielding: Metal shields or conductive coatings are used to create a Faraday cage effect, preventing external ESD from interfering with internal circuitry.

4. Grounding Techniques: Proper grounding ensures that ESD energy is safely directed away from the PCB, reducing the risk of damage.

5. ESD-Resistant Materials: Using anti-static coatings or materials in PCB construction can minimize static buildup and discharge risks.

By implementing these ESD protection methods, arcade PCBs can maintain optimal performance and longevity, even in high-static environments.
