EMI/RFI Shielding

Thermal Spray Process to Achieve EMI/RFI Shielding

EMI/RFI Shielding is a major concern in the electronic industry as devices become more and more interconnected. Keeping sensitive data in and interference out, TEMPEST-qualified EMI/RFI shielding surfaces from Hayden Corp provide a first line of defense in data security.

What are EMI and RFI?

EMI stands for electromagnetic interference. EMI is any type of unwanted electric or magnetic energy that can disrupt the normal operation of an electronic device. The sources of EMI include cellular phone towers, ham radio operators, and radar transmitters. RFI, on the other hand, stands for Radio Frequency Interference. RFI is a type of EMI that is caused by radio signals. The sources of RFI include wireless keyboards, routers, and Bluetooth devices.

Achieving EMI / RFI Shielding Through Thermal Spraying

A thermal spray application by Hayden Corp can provide EMI/RFI shielding for your device, protecting it from electromagnetic interference (EMI) and radio frequency interference (RFI). The process of applying the thermal spray to the component surface causes an increase in conductivity that blocks any unwanted signals or noise.

How Does Shielding Reduce EMI?

Thermal spray can help to reduce EMI in a number of ways. The physical barrier created by the thermal spray coating helps to prevent any electromagnetic energy from entering or exiting the device. The increased conductivity of the thermal spray also helps to dissipate any electrical charges that could cause interference. Additionally, the thermal spray will cover and protect component surfaces on the device, which can also act as an antenna and increase the chances of interference.

Some of the benefits of EMI RFI shielding thermal spray coatings by Hayden Corp include:

- decreased electromagnetic interference (EMI) and radio frequency interference (RFI)

- increased device reliability and performance

- reduced manufacturing and assembly costs

- improved product lifespan

- reduced scrap and rework

- compliance with global regulations

Typical Applications and common parts that need EMI/RFI Shielding?

Developed to meet the needs of government and military contractors, EMI/RFI Shielding coatings by Hayden Corp provide shielding performance superior to metallic paint, with far higher bond strength of nearly any geometry to be protected.

Typical applications of EMI/RFI Shielding Thermal Spray include:

Computer and Display Housings

Active capture of emissions by grounding of the shield surface significantly reduces the likely hood of data theft or compromisation. The EMI shield also reduces any potential for RFI interference.

Navigational and Telemetry Equipment

Complete data protection is provided by Hayden's EMI/RFI Shielding Thermal Spray process. Both conductive and dissipative surfaces are possible to protect sensitive electronic equipment used in fiber optics, lasers, radar, sonar, space research, avionics and more.

Surface Protection for Electronic Components

Hayden Corp EMI/RFI Shielding Thermal Spray process provides a barrier layer of protection against the elements, moisture and many corrosive contaminants for electronic components.

Cabinet Systems TEMPEST

Eliminates cabinet screws that can leave screw heads exposed to outside interference, as well as unwanted entry into a secure enclosure. Excellent EMI/RFI shielding for high-security applications.

Power Supplies, Cabinets and Chassis

The thermal spray coating provides a robust, durable surface that can both protect the device from tampering as well as increase performance by dissipating electrical charges.

Thermal Spray Coating to Achieve EMI/RFI Shielding

There are a number of factors that you should consider when choosing a thermal spray coating to provide EMI/RFI shielding for your device. The type of device, the type of interference, and the environmental conditions all play a role in determining which coating is best for your application. You should also work with an experienced thermal spray applicator to make sure that the coating is applied correctly and provides the best possible protection for your device. Hayden Corp is a thermal spray applicator with over 100 years of experience in the industry. We offer a wide range of thermal spray coatings that can provide EMI/RFI shielding for your device.
