EMI Market Trends and Solutions

Electromagnetic interference (EMI) — also called radiofrequency interference (RFI) when occurring in the radiofrequency spectrum — refers to an electromagnetic disturbance caused by an electronic device interacting with another electronic device. Electromagnetic induction, electrostatic coupling, and conduction can all disrupt the electrical circuit of the affected device. EMI can cause major problems for a huge range of applications, and is becoming a greater concern in today’s increasingly connected world.
EMI Solutions
Ever wonder why wireless devices must be put on airplane mode or turned off during a flight? Electromagnetic waves emitted when using those devices can actually interfere with the plane’s navigation system.

As the use of technology and electronic devices continues to rise, the EMI shielding market is rapidly expanding. Government guidelines outlining EMI shielding requirements are also expected to shift. And as technology use increases, electronic devices are becoming smaller and smaller, and the use of Wi-Fi, GPS, and Bluetooth is becoming more and more common. Both of these trends — the miniaturization of devices and the increased use of wireless technologies — can contribute to EMI problems.

EMI Shielding Materials

EMI shielding is extremely important in today’s ever-shifting landscape, and we’re proud to partner with Parker Chomerics, a leader in EMI shielding innovations offering a range of different of products including:

EMI Shielding Gaskets

EMI shielding gaskets from Parker Chomerics can eliminate all types of EMI gaps. Common applications include EMI window seals, grounding tabs, server face plates, panel seals, cover seals, and door seals.

EMI Shielded Window

These windows not only guard against EMI, they also protect displays from scratches and breakage, and can withstand harsh conditions. EMI shielded windows can be used with the above-mentioned EMI shielding gaskets, as well. Common applications include electronics used in military and medical environments, instrument panels, and cabinets and racks.

Metal Foil Tapes

Parker Chomerics offers a few different types of shielding tapes, available in aluminum, copper, tinned copper, nickel-plated, and, if appearance is a concern, embossed types. These tapes are perfect for EMI cable shielding, especially when dealing with surfaces that cannot be soldered.

EMI Shielding Paints

Paints are ideal for scenarios in which common EMI shielding products will not work, such as high-altitude environments. You would not want to wrap EMI shielding tape around an airplane, for example. Parker Chomerics offers a range of different paints to suit specific shielding applications, such as circuit boards, plastic enclosures, electrolytic platable plastic, aircraft airframes, and aluminum and composite.

Electrically Conductive Adhesive

Various types of adhesive are available from Parker Chomerics, all designed for use in applications requiring sturdy, conductive electrical bonds. Adhesives are often used to fill cracks in electrical boxes, poor-tolerance enclosures, and EMI vents and windows.

Electrically Conductive Sealants

Sealants are important for filling in gaps on electrical enclosures or electrical grounding. This is often required for man-portable electronics, military ground vehicles, and radar and communication systems.

Henkel Adhesives Provide High-Performance Solutions

Wearable electronics demand requires performance and reliability under the most adverse conditions. Exposure to shock, stress, vibration, extreme temperatures, and water/moisture can’t be allowed to affect performance and reliability. In this rapidly growing market where less is more, there is no place for bulky adhesive products on devices where size and limitations are crucial. Manufacturers of wearable technology depend on Henkel for the adhesive solutions they need to take their complex products from the design table to the production line.
