Rapid advancements in electromagnetic interference (EMI) shielding technology has served to make the driving experience in modern vehicles smooth and hassle-free. The addition of new systems, such as on-board GPS, in-vehicle communication, wireless charging, and touchscreen infotainment, is a big draw for modern consumers and increases the value of a vehicle considerably. Unfortunately, these devices are also responsible for the emission of unwanted EMI. The problem is compounded by the constant use of smartphones, tablets, and other wireless equipment in and around cars. While these emissions pose a threat to automobile applications, they create opportunities for shielding materials to grow in this sector.
More EMI in Vehicles Means More Shielding
EMI emission varies across automobile technologies, and so does the need for EMI shielding. For example, protection is a must in cars employing advanced electronics for engine performance. Still, automobile manufacturers need to get in touch with EMI shielding suppliers and implement the technology early on during the design stages. That’s because, the more personalized and innovative the solution, the better.
Electric motors and other electronic systems appear to be the most culpable among all automobile technology. They emit massive levels of EMI that cause widespread problems, ranging from malfunctions to breakdowns. So, for the protection of the different components in vehicles and ensuring they are compatible, modern car designers should make provisions for EMI shielding.
Relation Between Automobile Manufacturing Materials and EMI
The evolving nature of the materials used to construct modern vehicles means EMI shielding must keep up at all times. New vehicles utilize sheet metal to deter external EMI. With more and more automobile companies switching to non-metallic components for the production of auto body parts, it might be a good idea for shielding engineers to redirect their efforts towards devising a foolproof solution for the protection of the vehicle interiors.
Hurdles in Store
The process of designing EMI shielding for a new vehicle model is time-consuming and expensive, but it should not be neglected. Detection of EMI issues late in production can bring the manufacturing process to a halt while the engineers attempt to uncover what went wrong. Perhaps the biggest hurdle lies in figuring out the perfect moment to install shielding in vehicles. Often, EMI signals, like those produced in vehicle interiors, are so faint that it is difficult to figure out which components are at risk. But implementing EMI shielding during the design process increases its effectiveness while decreasing the cost.
The growing demand for integrated electronics within vehicles means the EMI shielding industry will need to step up its game. There will be hurdles, of course, but with the right design, materials, and manufacturing process, successful EMI shielding can be a reality.
