The proliferation of wireless technology has occurred rapidly over the past few years and it has led to new opportunities. However, along with the benefits come the challenges. In this context it is electromagnetic interference (EMI), which can either be in the form of electromagnetic radiation or electromagnetic induction that originates from an external source and interferes with the performance of a nearby circuit. In some cases, EMI can cause circuit shutdown. Proper electromagnetic interference shielding is an effective method of securing devices from the harmful effects of EMI. Owing to advances in wireless technology along with the miniaturization of electronic gadgets, the EMI shielding industry has experienced record growth while dealing with a slew of challenges.
Demand for EMI Shielding
The influx of new forms of wireless technology, such as 3G, Bluetooth, Wi-Fi, RFID, and GPS, has created plenty of new opportunities for problems resulting from EMI. In contrast, this provides EMI shielding designers with greater impetus to solve these issues, which has had a direct impact on the business and personal sectors. Most contemporary power electronics come with EMI filtering circuits or have internal EMI filters, both of which need the talents of a professional EMI shielding designer. The wireless communication industry has use for effective EMI shielding within their electronic device systems.
Wireless Technology Makes EMI Shielding Relevant
EMI can be generated anywhere on the planet, and the amount of electronic devices that require protection from it is only going to increase with time. Mobile phones are becoming smaller yet feature-enriched while wireless communication systems are increasing in complexity. And as more and more devices vie for attention, it only increases the requirement for advanced EMI shielding solutions. Impact of Personal Wireless Use on Shielding Manufacturers
Electronic technology has touched our lives in different ways, evolving quickly to serve arenas such as military, aerospace, telecommunications, and health care. This rapid evolution demands changes in the designs of wireless consumer products, like cell phones, fitness trackers, laptops, tablets, personal drones, and GPS systems. These items continue to integrate greater number of features into tinier footprints, and as a result, the amount of space available for quality EMI shielding also becomes smaller. With this kind of probability for potential EMI issues affecting large quantities of design orders, lots of EMI shielding solution providers have approached their design departments with the hopes of making them more specialized. The goal is to provide them with the resources necessary to meet the requirements of specific markets successfully.
Evolving Face of EMI Shielding
Along with the uptick in the number of innovative wireless technologies, come stricter restrictions and regulations. This has prompted different EMI shielding specialists to figure out new and improved methods to utilize less amount of space along with lighter/thinner materials during the creation of shielding to higher tolerances. This might sound rather difficult but for shielding designers, who have loads of experience in the process, meeting these challenges is more of an evolutionary process. Even though space remains at a premium and expenses must be borne in mind more than ever before, the basic task that needs to be completed remains more or less the same – selecting the proper shielding technique that will be suitable to an application in question along with the creation of a shield that will be able to deter all external interference successfully.
Wireless technology is an indispensable component in today’s world. However, it also brings with it certain problems, foremost among which is electromagnetic interference. For this purpose, developments in the field of electromagnetic interference shielding have gained impetus. As a result of these advancements, industries employing electronic technologies are now better equipped to deal with EMI problems.
