  EMI/RFI Shielding
EMI (Electromagnetic Interference)/RFI (Radio Frequency Interference) is any electromagnetic radiation or disturbance which is emitted from an electrical circuit or electronic device. EMI/RFI may be introduced intentionally as in the case of electronic warfare, or unintentionally from an electronic or electrical device or system. EMI may also be created as a result of a nuclear detonation. EMI/RFI Shielding should be an integral consideration to electronic device or electronic system design. Good design techniques should include sound Electromagnetic shielding, as well as attenuation to the bonding of the ground points. Matrix Coatings is a leader in providing shielding and conductive coating solutions for EMI/RFI problems on plastic enclosures. This product family (Spraylat and Acheson Colloids) includes silver-coated copper, pure silver and hybrid coatings. Matrix Coatings has earned a reputation for solving demanding problems through the use of these uniquely blended coating systems. Matrix Coatings also offers other specialty conductive coatings for protection of structural plastics such as composite materials from damage due to lightning strikes. Thermal (ARC) sprayed metallizing is also used to provide shielding on steel electronic enclosures in order to harden them against nuclear devices that are detonated in the atmosphere for the specific intention of disrupting the performance of the housed electronics within the enclosure. There are many different products designed to provide a wide range of performance characteristics for varying environmental concerns. The list of coatings is too lengthy to list here. The following represents coatings used for this purpose:
 


Praxair/Tafa Arc Spray Zinc – 02Z

Made exclusively for arc spraying, zinc 02Z is primarily designed for use as an EMI/RFI shield, capacitor end spraying and protective anti-corrosion coating for general oxidation resistance. Arc spray 02Z is 99.99% pure, and is not contaminated in the arc spray process. Zinc 02Z wire meets the Department of Defense Specification MIL-W-6712C, Table II, Zinc. Traditional applications of zinc have been used primarily for corrosion protection, both in the atmosphere and in the marine environment for long-term anti-corrosive service.

Praxair/Tafa Arc Spray Pure Tin Alloy Wire – 02W

Made exclusively for arc spraying, pure tin is a low melt material with excellent solderability, conductivity and corrosion resistance. Arc spray tin wire meets Department of Defense Specification MIL-W-6712C, Table II, Tin. This wire is commonly used in electrical applications to produce solderable coatings for electrical connections and as a very effective EMI/RFI shield. It is also extremely corrosion resistant to a variety of chemicals and solvents and may be used as a tank liner in some applications.

Lastly, we maintain a selection of Tafa metallizing wires, Acheson Colloids, Spraylat and other products in stock, eliminating costly waiting for products to arrive in order for a job to begin.
