Sono-Tek Corporation announces the release of a new ultrasonic coating system, the FlexiCoat EMI, specifically designed for conformal spraying of EMI (Electromagnetic Interference) shielding material onto semiconductor packages.
由于需要改善EMI屏蔽保护特性的较小设备，因此这个新市场的兴趣和活动越来越大。诸如屏蔽罐和SMT夹之类的传统技术对于新的小型设备不足。超声波涂层是一种具有成本效益，更快，更简单的替代品，可用于昂贵的基于溅射的涂料设备。app亚博体育
Sono-Tek的Flexicoat EMI是一种自动化的XYZ涂料系统，专门设计并经过证明，可以喷洒铜和银色的屏蔽材料，具有精确控制涂层特性和少量涂料的精确控制。亚博网站下载
Sono-Tek ultrasonic nozzles are widely known for their low/no maintenance, non-clogging, high uniformity and highly repeatable performance. A special ultrasonic nozzle configuration was developed for these EMI applications to provide a more targeted spray area that reduces overspray drastically when compared with all other spray types. This new nozzle design is fully integrated into the FlexiCoat EMI system, along with an array of application-driven features to make the system a full coating solution for EMI shielding coatings.
Flexicoat EMI系统的某些功能包括：
- 500x500 mm slides, conveyor and pumping system
- Proprietary ink mixing system to ensure ink stability over time
- UPH/throughput is significantly faster than sputtering at 1/10 the price
- 与Tatsuta和其他墨水提供商的墨水配方兼容
- Uniform shielding coverage on top and sides of package is achieved using nozzle tilt
- 顶表：侧壁厚度比为1：0.6〜0.7
Sono-Tek销售与营销副总裁Bennett Bruntil表示：“我们进入这种不断增长的半导体应用程序是我们在其他应用中的半导体涂料专业知识的自然产物。我们的设app亚博体育备很快被证明非常适合寻求有效，低成本的替代品，用于溅射市场上的新铜和充满银色的环氧材料。亚博网站下载
