Innovative Solutions for Package-Level Electromagnetic Shielding
Cheersonic Ultrasonic Spray Coating Platform: Innovative Solutions for Package-Level Electromagnetic Shielding
As electronic devices continue to achieve higher levels of integration, package-level electromagnetic interference (EMI) and radio frequency interference (RFI) have become critical bottlenecks constraining product performance. Cheersonic’s ultrasonic spray coating platform offers a targeted solution for package-level electromagnetic shielding coating preparation, providing an efficient pathway for shielding coating processing on various precision electronic components. With its unique technical characteristics, this solution is progressively breaking through the limitations of conventional coating processes and demonstrating significant advantages across multiple high-end manufacturing sectors.
At its core lies the precise synergy between ultrasonic spray coating technology and flexible curing processes. Ultrasonic spraying atomizes conductive coating materials into micron-sized particles through high-frequency vibration, producing droplet uniformity far superior to traditional spraying methods. This is complemented by low-temperature thermal curing tailored to the shielding material’s properties, ensuring both coating adhesion stability and protection of precision components from heat damage. Compared with mainstream sputtering and other vacuum-based coating equipment, this innovative process achieves a qualitative breakthrough in cost control—vacuum equipment not only requires substantial initial investment but also incurs high energy consumption, maintenance costs, and material wastage during operation. In contrast, the ultrasonic spray system achieves material utilization rates exceeding 90%, with energy consumption only one-third that of vacuum equipment, substantially reducing total production costs for manufacturers.
Among the offerings, the UAM6000 fully automatic XYZ motion spray coating system stands as a technological benchmark. Equipped with a high-precision motion control module, it precisely controls conductive coating film thickness within the nanometer-to-micrometer range, with coating uniformity deviation below 5%, completely resolving the issue of uneven coating thickness found in traditional processes. Particularly noteworthy is its exceptional sidewall coverage capability—for complex structured components such as semiconductor packages and PCB boards, it enables 360-degree no-blind-spot spraying, effectively enhancing shielding coating integrity and shielding effectiveness, ensuring stable operation of electronic components in complex electromagnetic environments.
To accommodate production needs at different stages, Cheersonic offers a full range of equipment options: benchtop R&D tools facilitate laboratory formulation debugging and process optimization; pilot-scale equipment enables small-batch production, accelerating technology transfer; and in-line conveyor-type coating systems are specifically designed for mass production, seamlessly integrating with automated production lines to provide stable support for high-volume manufacturing in fields such as PCBs, semiconductor packaging, mobile terminals, automotive electronics, aerospace, and communications equipment.
From miniaturized packaging in consumer electronics to high-reliability requirements in aerospace, the Cheersonic ultrasonic spray coating platform—with its efficient, cost-effective, and precise characteristics—redefines the processing standards for package-level electromagnetic shielding coatings, offering robust assurance for electronics manufacturers to address electromagnetic compatibility challenges and enhance product competitiveness.
