Electromagnetic interference (EMI) can disrupt the performance of arcade cabinets, causing glitches or malfunctions. To minimize EMI, consider these proven methods:

1. Proper Shielding: Use conductive materials like copper or aluminum foil to shield sensitive components. Enclose high-frequency circuits in metal casings to block interference.

2. Grounding Techniques: Ensure all components are properly grounded to divert unwanted electrical noise. Use a single-point grounding system to avoid ground loops.

3. Cable Management: Keep power cables and signal wires separated to reduce crosstalk. Use twisted-pair or shielded cables for critical connections.

4. Ferrite Beads: Install ferrite beads on power and signal cables to suppress high-frequency noise.

5. Component Placement: Position high-power components away from sensitive circuits to minimize inductive coupling.

By implementing these strategies, you can significantly reduce EMI and enhance the reliability of your arcade cabinet.
