Electromagnetic interference (EMI) can disrupt the performance of arcade cabinets, leading to glitches or malfunctions. To combat this, manufacturers use various EMI shielding techniques. The most common types include:

1. Conductive Coatings: Applied to the interior surfaces, these coatings block EMI by creating a conductive barrier. Materials like nickel or copper are often used.

2. Metal Shielding: Arcade cabinets often feature metal enclosures or Faraday cages, which absorb and redirect electromagnetic waves away from sensitive components.

3. Conductive Gaskets: These are used around doors or seams to ensure a continuous shield, preventing EMI leakage.

4. Ferrite Beads: Attached to cables, these beads suppress high-frequency noise, reducing interference in power and signal lines.

5. Shielded Cables: Wrapped in conductive material, these cables minimize EMI from external sources.

By implementing these methods, arcade cabinets maintain optimal performance and longevity, ensuring a seamless gaming experience.
