You’ve been careful with the layout — and the EMC report still comes back with failures you didn’t see coming.

You know what you need to check. The answers are scattered across forum posts, application notes, and textbooks that contradict each other.

It’s not the first time this class of problem has appeared in your designs. The same mistakes keep repeating because there’s nowhere that shows them all in one place.

The difference

Designing without a reference vs. with one

Without the guides

✗Finding out what fails in the test lab — after it fails

✗Looking up the same antenna theory on every project, never quite trusting the source

✗Running through EMC rules from memory and hoping you haven’t missed one

✗Fixing EMC problems under deadline pressure with no structured approach

✗Building knowledge the slow way — through expensive failures

With the guides

✓Antenna theory applied to PCB layout — 40 pages you open before the design goes to fab

✓The 10 layout decisions that cause most EMC failures, with corrective actions for each

✓A checklist-style reference you run through every design before sending it to the lab

✓A troubleshooting guide organised by problem type — for when you’re under pressure

✓EMC knowledge from real project experience across medical, industrial, and aerospace

What’s inside

Three guides. One for every stage of an EMC problem.

eBook · 40 pages

Radiated Emissions & EMI Control

Electromagnetic fundamentals applied to PCB layout. Covers antenna theory, return current management, stackup selection, and layout strategies that control radiated emissions before you enter the test chamber. You use this one during schematic review and layout — when there’s still time to fix what matters.

Top 10 PCB Design Mistakes for EMC

The ten PCB layout decisions that cause the most EMC test failures — with real examples and corrective actions for each. A checklist you run through every design before it leaves your desk. These are the mistakes most engineers only discover in the test chamber, after the damage is done.

eBook · 24 pages

EMI Quick Fixes Guide

A troubleshooting reference for when problems show up during pre-compliance or in the test lab. Organised by problem type: radiated emissions above limit, conducted interference, power supply noise, signal integrity failures. Reach for this one when the clock is running and you need a structured path to a fix.

Also included — 3 bonus masterclasses

Radiated Emissions Masterclass — 45 min

PCB Design for EMC Masterclass — 40 min

EMI Troubleshooting Masterclass — 50 min

What EMC without a solid reference actually looks like

Situation 01

The test lab surprise

You’ve been careful. Decoupling caps on every IC, short traces, a solid ground plane. The EMC report comes back with radiated emissions 12 dB over limit and the test engineer can’t tell you why in a way that maps to a specific design decision. You spend the next two weeks reading forum posts and changing things that might help, hoping one of them does. One of them eventually does. You’re not sure which one, or why, which means you’ll probably be back here again on the next board.

Situation 02

The search that takes hours

You know the theory exists — return current paths, antenna theory applied to PCB layout, the relationship between stackup and emissions. Every time you need it, you’re starting from scratch: an application note from a component manufacturer, a thread on an electronics forum, a chapter in a textbook you half-read three jobs ago. None of them say quite the same thing. You end up trusting the one that sounds most confident, which isn’t the same as trusting the one that’s right. That costs you somewhere, eventually.

Situation 03

Fixing under pressure

Pre-compliance testing found a problem two weeks before the final lab booking. You’re not sure if it’s the switcher layout, the filter topology, the ground plane split, or something in the cable harness. You know roughly where to look but not in what order, and you can’t afford to chase the wrong thing first. There’s no structured reference for this moment — no guide organised by problem type that tells you what to check, in what order, and what to change when you find it. You figure it out eventually. It costs you a week you didn’t have.

What changes

Three guides, three problems solved.

The test lab surprise disappears when you have the antenna theory during layout — not after it. The Radiated Emissions guide covers exactly what makes a PCB radiate and why: antenna theory applied to real board geometry, return current management, and the stackup choices that change your emissions floor. You open it before the design is frozen. That’s the only time it’s cheap to act on it.

The 10 mistakes guide turns a multi-hour search into a 10-minute checklist. It covers the specific layout decisions that cause the most failures — not general principles, but the actual mistakes: where the cap goes relative to the IC, how the plane split creates a loop, why the via placement in a filter matters. Real examples, corrective actions for each. You run through it before every design review and catch the things you’d otherwise discover in the chamber.

The Quick Fixes guide is what you reach for when you’re under pressure and need structure. Organised by problem type — radiated emissions above limit, conducted interference, power supply noise, signal integrity failures — so you go straight to what’s relevant, not through everything hoping to find it. It doesn’t replace engineering judgment. It focuses it when there’s no time to waste.

Questions

What engineers usually ask

Both, for different reasons. Earlier-career engineers get a foundation that most engineers only build after expensive mistakes. Experienced engineers fill gaps — the most common feedback is that one specific section clarifies something they’d been getting half-right for years.

No. The course is a structured 11-module programme — you go through it once and build systematic knowledge. The guides are reference material: you open them during active design work when you need a specific answer fast. Engineers who’ve done the course use the guides as the desk reference alongside it.

PDF. You get a download link immediately after payment. Works on any device — tablet, phone, laptop. Print them if you want a physical copy on your desk.

Directly, the Quick Fixes guide is built for exactly this situation — organised by problem type so you go straight to what’s relevant under time pressure. The other two guides help earlier in the process: understanding what radiates and why means fewer surprises when you get to the chamber.

One purchase is for individual use. For team licences, contact info@fresuelectronics.com — it’s a common request and it’s straightforward to arrange.

Three video sessions — Radiated Emissions (45 min), PCB Design for EMC (40 min), and EMI Troubleshooting (50 min). They go deeper into the practical application of each guide topic. You get access to the recordings immediately after purchase.

The Standard membership is billed monthly by Skool. Cancel anytime.
