EMI/RFI shielding is a material that reduces the energy of electromagnetic waves that travel through it. EMI / RFI shielding is increasingly used to protect humans from potential harmful health effects of electromagnetic radiation. Typically, the objective of EMI / RFI shielding is to enable electronic devices to achieve EMC, so they can operate legally and efficiently. Whatever the use, EMI/RFI shielding functions as a conductor.
A portion of an electromagnetic wave will be reflected, absorbed, and transmitted when it collides with a conductive substance. The reflected and absorbed components will be exponentially larger than the transmitted component if the material is extremely conductive. In actuality, the scale used to quantify shielding effectiveness—the decibel scale—is an exponential one.
Now that you are aware of what EMI RFI shielding is, you should be aware that there are various types of EMI RFI shielding available based on the application.
On some circuit boards, shielding may be represented by a straightforward metal box. Materials utilised range from stainless steel to nickel silver and beryllium copper, and they could be mixed with foam or silicone elastomers
EMI RFI shielding can be applied in bigger iterations using an acrylic paint or spray on items like machinery or server rooms. Extremely pure, tiny metal particles, including copper, silver, and nickel, are evenly distributed throughout the protective covering of this acrylic coating.
Electromagnetic interference (EMI) can be found almost anywhere in today's globe. External signals that reach an electronic equipment and interfere with the device's signals are referred to as EMI. It has the potential to affect a wide range of functions, rendering certain devices utterly useless.
Electromagnetic interference (EMI) and radio frequency interference (RFI) are reduced and eliminated using shielding materials. Computers, microprocessors, radio receivers, medical equipment, measuring instruments, and navigation systems are just a few examples of today's electronics that require interference protection. Knowing how well shielding materials perform (i.e., how effective they are) offers the necessary protection to ensure that the devices function properly and safely.
On the market, there are a variety of EMI devices that can be included into a device design where EMI shielding is required. These EMI products include Honeycomb vents, conductive shielding gaskets, fingerstock gaskets, metalized fabric gaskets, and conductive elastomers, all of which contributes to increased EMI protection and efficacy in its own way.
Beryllium Copper is known by a variety of names. BeCu, Copper Beryllium, Beryllium Bronze, Alloy 172, and Spring Copper are some of the terms used to describe it. Beryllium Copper is referred to whenever you hear such phrases.
Beryllium Copper can be found in a variety of industries and applications. This is due to its strength and electrical and thermal conductivity, as well as the fact that it is non-sparking and non-magnetic.
Uses of Beryllium Copper
Electronic connectors, telecommunications goods, computer components, and miniature springs all use beryllium copper. Look closely at tools used on oil rigs and coal mines, such as wrenches, screwdrivers, and hammers, and you’ll notice the letters BeCu on them. They’re made of beryllium copper, therefore that’s what they’re made of. Workers in those industries require tools that are safe to use in those situations, which is critical. Tools constructed of beryllium copper, for example, will not create possibly deadly sparks.
How do Be/Cu fingerstrips work?
To avoid EMI/RFI radiation and interference from outside sources, modern electronic equipment frequently requires EMI/RFI shielding and an EMI/RFI-shielding gasket.
EMI/RFI gaskets made with the strengths of beryllium and copper (Be/Cu) are the industry standard all over the world. Be/Cu EMI/RFI shielding gaskets have been the solution of choice since the onset of RFI/EMI difficulties in the early days of military electronics.

Understand what is EMI shielding effectiveness and how measuring it ensures the proper functioning of today’s sophisticated electronic devices.
In order to ensure the proper functioning of the various sophisticated electronic devices used today, it is vital, among other things, to protect them from radio and electromagnetic interference. Excellent products are built with shielding components that have been tested for EMI shielding effectiveness. Understanding this critical metric provides reassurance that the devices chosen will hold up without worrying about interference from outside forces.
What Is EMI Shielding Effectiveness?
Because all electronics emit magnetic and electrical energy, interference is possible, causing devices to malfunction. Even unintentional interference can lead to severe problems. For example, a blimp of interference in a child’s toy doesn’t affect much. However, that same tiny bit of interference in a medical device can be devastating.
Shielding materials work to decrease and eliminate electromagnetic interference (EMI) and radio frequency interference (RFI). Today’s electronics have many components that need protection from interference, such as computers, microprocessors, broadcasting receivers, medical devices, measuring instruments, and navigation systems. Knowing how well shielding materials work (i.e., their effectiveness) provides the protection required to ensure the devices can function properly and safely.
There are several types of EMI products on the market that can be integrated into a device design where EMI shielding is crucial. These EMI products include honeycomb vents, conductive shielding gaskets, fingerstock gaskets, metalized fabric gaskets and conductive elastomers, all of which contribute in their own way to increased EMI protection and effectiveness.
What Are the Objectives of Shielding Effectiveness Tests?
Quality products have end-user objectives in mind. EMI shielding effectiveness tests are no different and accomplish three main goals based on how the device is designed:
Keep specific radio frequency signals within the enclosure of the device. Under EMI testing, it is determined if an electronic device generates signals within an acceptable range and limit.
Another objective is to block external electromagnetic interference from affecting the tested device. When an enclosure is not adequately shielded, it can be impacted by EMI. Areas most vulnerable include cables, fans, input and outputs, gaskets, seals, and controls.
The final objective is to measure if a device is capable of retaining all RF energy within its enclosure while keeping all external RF out. Each device is different and has unique tolerances based on its functionality and placement of operation.
How to Measure EMI Shielding Effectiveness
Shielding effectiveness is measured in different ways. One of the principal indicators is called attenuation. It is the difference between an electromagnetic signal’s intensity before shielding and then after shielding. Attenuation is measured in decibels (dB). This measurement corresponds to the ratio of shielded and unshielded devices in the field.
Generally, a signal’s intensity or amplitude decreases further away from the interference from the device. The lowest effective shielding falls within the range of 10-30 dB, and high levels of protection fall between 60 and 90 dB. It is possible to hit exceptional protection when shielding reaches over 90dB in attenuation.
Measuring an electronic devices’ attenuation is accomplished through four standard tests, including:
Open Field Test: Often used with finished products, open field testing is designed to simulate usage under normal conditions. Utilizing an available site that is free from other metallic equipment, antennas are situated at a variety of distances from the electronic device being tested. The open area allows for measurements of radiated field strength and conductive emissions.
Coaxial Transmission Line Test: This type of testing is used for comparative testing. It measures lane-wave field electromagnetic wave radiation in planar material. First, a reference testing device is placed in close proximity to the planar material. Measurements of voltage at multiple frequencies are recorded. Next, a load device is placed near the material, and those voltage readings at various frequencies are recorded. Finally, the measurements are compared to establish the ratio of power received both with shielding and without shielding.
Shielded Box Test: For testing frequencies less than 500 megahertz, a shielded box is used. This sealed box has an opening on one side in which a shielded test subject is inserted. Next, a coated shielding is placed over the opening. Then, electromagnetic signals from inside and outside of the box are compared. All transmitted and received emissions are measured. Once complete, the ratio between the signals determines the shielding effectiveness of the test device.
Shielded Room Test: If it’s vital to determine a device’s susceptibility, a shielded room test is a practical choice. Two shielded rooms with a wall in between them are used. One room holds the device being tested, while the other room holds the sensors. It is customary to have shielding leads used to minimize errors from external signals. This test is often used when it is difficult or impossible to diminish or eliminate ambient noise in an area.
What to Know About Beryllium Copper and EMI RFI Shielding
Today, most electronic devices are equipped with some form of EMI RFI shielding. Because of its exceptional properties, Beryllium Copper has become the material of choice when it comes to protecting electronic devices and parts against internal and external electromagnetic and radio frequency interference.
You can learn more about EMI RFI shielding by reading our previous article What is EMI RFI Shielding? In this article, we will, however, focus on Beryllium Copper and its important role in EMI RFI shielding.
What is Beryllium Copper and What is it Used For?
Beryllium copper, also called BeCu, is a high-performance metal that can be transformed into a wide variety of components. It has been the industry-standard material for EMI RFI shielding since the first instances of interference were found in military electronics. An alloy of copper with 0.5 to 3% beryllium, this substance is prized for its extremely high strength and non-magnetic properties, which make it suited to a wide range of applications.
Beryllium copper is used for everything from parts in hazardous environment tools to bullets, aircrafts, and even some musical instruments. In EMI RFI shielding, it is often combined with pure metals such as nickel, acting as a plating on protective components. These components are commonly used in the telecom, medical and transportation industries to protect vital equipment from error or failure.
Properties of BeCu
As an EMI RFI shield, beryllium copper is the industry standard, with a wide range of features that make it ideal for various protective applications. Here are some of the unique properties of beryllium copper:
Electrical and thermal conductivity: In order for EMI RFI shielding to work, it needs to be conductive. This conductivity absorbs interference either coming from within a piece of electronics or outside of it. Then, the interference is converted into an electric current which is distributed through the shielding. Beryllium copper is particularly effective at this and is able to distribute a current across X, Y and Z axis for even dispersion.
Fatigue Strength: Beryllium brings to copper a unique strength and resistance to fatigue which makes it especially forgiving to fatigue and repeated compression or movement. Pure copper is known for its malleability, which can work against it as a component in machinery where it will be subject to repeated strain. By making copper into an alloy, its tolerance increases immensely and it becomes reliable for far more intensive uses.
Hardness: A great asset of beryllium copper is its hardness when cooled, which, in the same vein as fatigue strength, gives it many uses as a core component in electronics, tools and other components where it might experience high levels of stress. This hardness also guarantees longevity, reducing the costs associated with frequent maintenance or replacement.
Corrosion Resistance: Compared to other copper alloys, beryllium copper is prized for its corrosion resistance in harsh down-hole or sea water environments. It is especially strong against chloride and sulphide exposure and is not prone to cracking over time.
Machinability: Beryllium copper has a solid melting point of 1590° F and a liquid melting point of 1800° F. This makes the alloy particularly well suited to being formed when hot, which is why it is so widely used for the manufacturing of precision components.
