Protective Coatings for Package Level EMI Shielding

Package level EMI (Electromagnetic Interference) shielding spray coating with precise thickness control

Ultrasonic coating technology, followed by a low temperature heat cure, offers a cost-effective alternative to costly sputtering-based coating equipment for package level EMI (Electromagnetic Interference) shielding processes. High performance silver EMI shielding spray coating materials are applied with Sono-Tek’s FlexiCoat fully automated XYZ motion coating systems in mobile device manufacturing processes. FlexiCoat is available as an in-line conveyor configuration for high throughput processes.

Sono-Tek’s non-clogging ultrasonic coating technology is well known for ultra-thin micron layer coatings of functional and protective materials. The ultrasonic vibration of the nozzle effectively disperses particles in suspension and produces very uniform dispersion of particles in thin film layers without conductive particle settling out of suspension.
