Coating-level EMI shielding

The silver coating used for packaging EMI shielding has been quickly transferred from the laboratory to the production department. Smartphones and other smart devices are becoming more and more compact, requiring higher performance EMI shielding effectiveness.

The key to accept these new EMI materials is the excellent coating ability of Shanghai Yangmi's core technology. This ultra-thin coating application technology is used for thin and uniform application of various coatings from pure solution to high solid suspension and slurry. Shanghai Yangmi ultrasonic spraying technology is combined with the liquid conveying system of precision metering pump. This system is a part of the spraying system platform, which has the nozzle movement and positioning system and the transportation system of the substrate to be sprayed.

Electromagnetic interference (EMI) is a process by which destructive electromagnetic energy is transmitted from one electronic device to another through radiation or conduction paths or both. In electronic components, devices and systems, EMI will adversely affect the performance of today's faster and smaller electronic devices containing digital circuits. EMI shielding can help designers get the highest operating and processing speed from the smallest physical package possible, without interference that will degrade performance.

Ultrasonic spraying system adopts advanced spraying technology to accurately control flow rate, coating speed and deposition. Low-speed spray molding defines atomization spray as an accurate and controllable mode to avoid overspray when producing very thin and uniform coatings. Ultrasonic spraying has been proved to be a reliable and effective method to deposit photoresist on 3D microstructure, thus reducing equipment failure caused by excessive exposure of metal to etchant.
