Ooops... Did it pass or not? [Butterflies in your stomach] For many electronics engineers, that’s exactly the feeling when they see a call from the EMC Test Lab. How can you feel confident when you’re dealing with what seems like black magic? That is the problem. Controlling electromagnetic interference is still seen as black magic rather than science. The result is that many engineers keep failing EMC tests with their designs and get stuck in a costly re-spin cycle. And when fixes are applied, they are often just guesses, not engineered solutions. The few engineers who have truly mastered EMI control are the ones who planned for it from the start. Your EMC test results are simply the outcome of how much attention you give to every detail of your PCB layout and system design. It is the difference between choosing a PCB stack-up that passes the first time or ending up with a bulky filter that does not fit in production. In the end, mastering EMI control is a choice. Do more (and cheaper) now, or do less (and pay more) later. You always have the choice: prevent or fix. To electromagnetic enlightenment, Dario P.S. If you are among those who prefer to prevent rather than fix at the last minute, here is the link to my academy, where we give you everything you need to make EMC a worry of the past. 👉 Join here: https://fresuelectronics.com/academy

Just like in spring, we need to do some cleanup every now and then. That is also the case for the old and outdated electronic circuit models that are still being taught in many schools. You need a fresh perspective if you want to unlock EMC design. You can’t make sense of things if you don’t see them from the right perspective. EMI will look to you like an invisible, uncontrolled spreading force that is impossible to tame. Like the flame of a fire you are trying to turn with gasoline instead of water. It is just not going to make sense. And the ways you try to fix it will sometimes only make things worse. All because of wrong models. Yes, because when you have the wrong models, you make the wrong decisions. Wrong decisions simply lead to bad results. You are not stupid, you just followed the wrong plan. And when you learn things the correct way, you will see how simple everything becomes. This is why I am sharing some of the EMC/EMI design course lessons for free. Because I want you to see, so that you can start implementing this in your designs and start reaping the rewards. You can find the free crash course at the link below.

What separates the EMI experts from everyone else is pattern recognition. The expert doesn’t need to simulate everything from scratch, they know where to look first. Expertise doesn’t come from time. It comes from clarity, knowing what matters, what doesn’t, and how to act fast. When it comes to EMC, most engineers spend months trying to fix issues blindly. They try filters, shielding, ferrites, without understanding what the real problem is. They patch symptoms instead of solving at the source. That’s why they stay stuck. But when you learn to see the issue clearly, thinking in first principles, that’s when you can look at a PCB and instantly know where energy flows, what radiates, and why. That’s when things change. You stop guessing, and you start solving. Because when a company is bleeding money in testing delays, they don’t want a lecture on Maxwell’s equations. They want someone who can walk in, identify the problem, and tell them exactly what to fix. That’s the skill that commands premium rates. And that’s also where your career can take off. You set yourself apart from the other engineers and their predefined path. The question is, how do you get to that point? Simple, start for free by clicking here.

To get paid well as an electronic engineer, you need to solve the most complex problems. Not only that, you need to do it extremely well and fast. Take EMC for example. For most engineers, this is still considered black magic, but for those who have mastered it, it can become very profitable. Why? Because companies cannot afford to stay stuck in EMC testing cycles. They need solutions, and they need them fast to stop losing money. This is where EMI specialists can help. A project review that finds the right issues can take less than an hour if you know what you are doing. This is what companies are willing to pay well for. If they spend a few thousand to pay you, but you solve a problem worth 100K or even more than 1M, paying you feels like nothing. The faster you deliver results, the more you can get paid. At this point, average salaries stop making sense, because you get paid in proportion to the problems you can solve. This is why you need to specialize if you want to earn more. The question is, where can you specialize? The answer is right here, starting for free: Click to check the classrooms. To electromagnetic enlightenment, Dario PS.

- Designing LTspice filters - Wrapping devices in "shielding" - Adding earth wires for “better grounding” Then they panic when project deadlines approach and the product fails EMC certification, because every test means another costly redesign. There’s a better (and proven) way. The engineers who consistently pass EMC tests do things differently: - They design the PCB stack-up to contain and guide energy effectively - They design layouts and geometries that don’t turn the board into an antenna - They design the entire product to minimize unwanted parasitic interactions with the environment All the real EMC work happens before the product ever comes to life. That’s why top engineers and EMC specialists don’t fear certification, because they’ve already engineered success into their design. This approach saves thousands of dollars, reduces stress, and makes projects profitable faster. If you want to learn how to design like that, and become an EMC specialist yourself instead of depending on expensive consultants, join my EMC/EMI Design course, click here to learn more.
