IC Cover Ink Spray Scheme Core advantages of ultrasonic spraying (compared to traditional spraying) 1. Ultra high uniformity - Atomized particle size: 5-50 μ m (adjustable), CV value<5% - Film thickness control accuracy: ± 1 μ m (applicable to 2-20 μ m coatings) 2. Material utilization rate>95% - Directional spraying reduces overspray and saves high cost ink (such as PI, epoxy resin) 3. Zero solvent damage risk - [...]

Circuit Board Shielding Coating In sophisticated electronic devices like smartphones and satellite navigation systems, circuit boards act as the "nerve center," supporting the operation of complex functions. However, potential threats such as electromagnetic radiation, humidity fluctuations, and dust intrusion constantly test the stability of these electronic components. Circuit board shielding coatings, as an invisible protective layer, are providing a strong defense for electronic devices with their unique properties. [...]

Circuit Coating Hidden between delicate integrated circuits and components lies a crucial material: circuit coating. It's not the core transistor or capacitor, but rather acts like a lubricant and protective layer in precision machinery, its thin film providing an indispensable barrier for the stable operation of electronic devices. This core function lies in comprehensive protection. Electronic devices are constantly exposed to threats such as moisture, oxygen, contaminants, and [...]
