EMI/RFI SHIELDING電磁屏蔽材料

電磁干擾 (EMI) 與射頻干擾 (RFI) 是電子系統三種主要干擾的其中兩種。根據其來源可分為外界和內部兩種,每個電子電氣設備均可視為干擾源。EMI是在電子設備中產生的不需要的響應;RFI則從屬于EMI。

Electro-Magnetic Interference (EMI) and Radio Frequency Interference (RFI) are two of the three major interferences in the electronic system. According to sources, they can be divided into internal interference and external interference. Each electrical and electronic equipment can be regarded as the source of interference. EMI is the unwanted response generated in the electronic device, while RFI belongs to the EMI.

現代的電子產品,功能越來越強大,電子線路也越來越復雜,電磁干擾(EMI)和電磁兼容性問題變成了主要問題, 電磁干擾可使電子系統的性能發生變化、減弱,甚至導致系統完全失靈,由此催生了屏蔽的技術的研究,發展和應用。

For modern electronic products, functions are more and more powerful, and electronic circuits are becoming increasingly complex. Electro-Magnetic Interference (EMI) and electro-magnetic compatibility becomes a major problem. EMI can change, diminish the performance of the electronic system, or even lead to complete system failure. This gave birth to the research, development and application of shielding technology.

屏蔽是對兩個空間區域之間進行金屬的隔離,以控制電場、磁場和電磁波由一個區域對另一個區域的感應和輻射。具體講,就是用屏蔽體將元部件、電路、組合件、電纜或整個系統的干擾源包圍起來,防止干擾電磁場向外擴散,用屏蔽體將接收電路、設備或系統包圍起來,防止它們受到外界電磁場的影響。但在電子系統輕量化的今天,塑膠部件被大量使用,因此使用具有導電性能的材料對殼體進行二次加工變成了一種解決EMI/RFI干擾的重要手段。近幾十年來,導電涂料已在電子、電器、航空、化工、印刷等多種軍、民用工業領域中得到應用。與此相應,導電涂料的理論研究也得到迅速發展,并促進了應用技術的日益成熟與完善。

Shielding is using metal barriers to isolate two space regions, in order to control the electric field, magnetic field and electromagnetic waves from one region to another region in terms of induction and radiation. Specifically, a shield is used to surround the component parts, circuit, assembly, cable or interference source of the entire system so as to prevent the outdiffusion of electromagnetic interference. The shield surrounds the receiving circuit, device or system to protect them from the external electromagnetic field. But in today's lightweight electronic systems, plastic components are widely used, so the use of conductive coatings with properties of the housing secondary processing becomes an important means of solving EMI/RFI interference. In recent decades, the conductive coating has been applied in a variety of military and civilian industrial electronics, electrical appliances, aviation, chemicals, printing and the like. Accordingly, the theoretical study of conductive coating has also been developing rapidly, and to promote the application of technology has become more sophisticated and Improvement.

匯眾電子提供各種具有不同配方的導電性能的材料,這些材料以銀,鎳或混合金屬為基礎填料,結合高性能的聚合物,確保了這些材料能夠通過IEEE 299-1997標準。通過噴涂,浸涂或刷涂能夠在塑膠外殼內壁形成一層均勻的導電,耐磨,附著力強的導電涂層,為電子系統的電磁干擾提供高性價比的解決方案。

Wilkon provides various conductive coatings with different formulations. These coatings use silver, nickel or mixed metal as based fillers, and combine with high-powered polymer to pass the IEEE 299-1997 standard. By spraying, dipping or brushing, a uniform conductive, wear-resistant, strongly adhesive coating can be formed on the inner wall of the plastic housing, providing cost-effective solutions to EMI in electronic systems.
