Ultrasonic spraying technology, combined with a low-temperature thermal curing process, offers a cost-effective alternative to expensive sputtering equipment for package-level EMI shielding. High-performance silver-based EMI shielding spray materials are applied in mobile device production using a fully automated XYZ motion-controlled spray system. This system can be configured for in-line transfer mode to meet high production throughput requirements.

As device designs evolve towards thinner and lighter designs, shielding solutions are shifting from board-level shielding to integrated circuit package-level shielding, enabling higher circuit board densities. After packaging, ultrasonically sprayed silver-filled polyester coatings can be applied as an alternative to sputtering.

Ultrasonic spray systems are a fraction of the cost of sputtering and are also used as an alternative to chemical vapor deposition (CVD), particularly in cost-sensitive manufacturing environments. Highly effective EMI shielding spray coatings enable high processing speeds without interruptions or performance issues caused by electromagnetic interference from surrounding equipment.

Advantages of Ultrasonic Coating Technology for EMI Shielding Coatings:

• Uniform Coverage: Achieves complete, uniform film coverage even on complex geometries.
• Optimal Thickness Ratio: Top-to-Sidewall Thickness Ratio of 1.0: Approximately 0.6-0.7
• Excellent Conductivity: Uniform particle distribution and excellent surface conductivity
• Efficient Shielding for Small Devices: Provides effective shielding for small devices.
• Excellent Coverage in Confined Spaces: The tilt and rotation capabilities of the nozzle enable ideal sidewall coverage in compact designs.
• Precise Thickness Control: Precisely control coating thickness.
• Flexible Nozzle Control: Programmable tilt and rotation capabilities.
• No Backside Contamination: Effectively prevents backside contamination.
• Strong Adhesion: Proven adhesion.
• Easy and Cost-Effective: Easier and more cost-effective than sputtering.
