and it’s not an easy problem to solve. proper EMI mitigation is a super tough engineering problem that you can make an entire career out of (and make good money doing so). there are so many sneak paths that can pop up that it turns into a constant game of whack-a-mole… simple things like applying a piece of tape to a cable harness next to a metal plate can either make the product pass or fail a radiated emissions spec…it’s crazy. and the automotive industry is so behind in the latest tech, the whole chip shortage thing during covid was because they’re using way outdated process nodes that no one wants to invest money in. don’t get me wrong, my fellow EEs in automotive do a good job given what they have to deal with, but they don’t have the experience in RF like us cellular/radio guys… obviously.
