Spraying EMI Shielding Spraying EMI Shielding – Atomization Nozzle – Cheersonic The EMI will come when electromagnetic energy from external sources affects the electrical systems. Electromagnetic interference (EMI) can destroy the electronic equipment, equipment and systems which are widely used in the key Applications, such as medical, military and avionics; industrial touch screen; public transportation systems; and some functions in the vehicle. There are many factors for EMI including the man and nature. The results can range from data loss to system failure even beyond imagination. Ultrasonic spraying technology provides a cost-effective and efficient spraying method for the package-level EMI shielding process. For EMI applications, Cheersonic has developed a special ultrasonic nozzle configuration to provide a more targeted spray area that can greatly reduce overspray. As traditional spraying methods, electroplating and sputtering not only increase the cost, but the throughput
