PRE-CERTIFICATION EMC CONSULTING · 3 SPOTS PER QUARTER
THE DAY YOU ENTER
THE TEST LAB IS TOO LATE
TO FIX YOUR DESIGN.
Most EMC failures are caused by design decisions made months before anyone walked into a test lab.
We review your design files, find every issue, and give your team a clear,
prioritised list of what to fix — before you spend money on boards that won't pass.

What one failed test costs
Lost when you order new boards
Average cost of one failed campaign
Chamber fees, extra engineering hours, and schedule delays, and that's before any customer penalties
8 to 12 weeks of delay per respin, plus a difficult conversation with whoever is waiting for your product
Without anyone reviewing the actual design, teams keep failing for the same underlying reasons
— 01 · THE PROBLEM
The test report doesn't create
the problem. It
just tells you
where you hid it.
1
2
3
The product fails its first EMC test
The test report lands. The launch date moves. Your team has no clear idea what's actually causing it.
You try the obvious fixes
Ferrites, caps, filter changes. Re-test shows little improvement — or makes things worse.
New boards get ordered
8 to 12 weeks and real money, spent on a fix that might not work, because the root cause still hasn't been found.
EMC failures come from decisions made during design: how the layers are stacked, where return currents flow, how switching circuits are laid out. Those decisions happen weeks or months before the test. The chamber just makes them visible.
When a product fails, most teams start swapping components: add a ferrite here, change a cap value there, reroute a trace. Sometimes it helps a little. Often it doesn't. Either way, nobody looked at why the noise was there in the first place. So the next board has the same problem, and so does the one after that.

You go for test anyway
The deadline runs out. You ship knowing the product didn't get fully fixed, and hope nothing bad comes of it.
5
The next product has the same problems
Because nobody fixed the design. The same decisions get made again, and the cycle starts over.

What it costs when teams go through 3+ test attempts
One failed test: €15,000–40,000. Three attempts: regularly over €100,000 when you add up chamber fees, extra engineering time, delays, and penalties.
— 02 · HOW WE WORK
We review your design before you build it, so you don’t have to fail .
Most EMC consultants get called in after something goes wrong. Their job is to get you through the next test attempt, fast, usually with some shields or filtering. That's fine once. But because nobody examined what caused the failure, it comes back on the next product. We work differently: we review your design files before fabrication, find what will fail and why, and hand your team a specific plan to fix it. You build for a first pass.
STEP 01
We review your board's electromagnetic foundation
How your layers are structured, where return currents actually flow, how your power planes are set up — reviewed against what your design needs to pass, before we look at a single component.
STEP 03
We give you a clear, prioritised fix list
Not a generic report. A specific list of what to change, why, and how — written for your exact board, your layer count, your target standard. The most critical issues come first
STEP 02
We trace where the noise comes from and where it goes
How your layers are structured, where return currents actually flow, how your power planes are set up — reviewed against what your design needs to pass, before we look at a single component.
STEP 04
We support your team while they implement
Your engineers make the changes. We're available to answer questions, review corrections, and make sure nothing gets misunderstood. When you walk into the test lab, you know your design is ready.
— 03 · WHO THIS IS FOR
Here's who we work with.
WE’RE A GOOD FIT IF…
-
You run a hardware team building real products such as aerospace, automotive, industrial, medical, or defence
-
Your product has already failed EMC or pre-compliance testing, or you know it has risks and you're heading into the lab soon
-
You've tried fixing it yourselves and it hasn't worked, or you don't have deep EMC expertise in the team
-
You have a real deadline, a launch date, a customer delivery, a regulatory submission you can't push
-
You want your engineers to understand what was wrong, not just apply a fix and hope it sticks
-
You're willing to share your design files under NDA
WE'RE NOTA FIT IF...
-
You need a test lab, a certification body, or someone to sign a declaration of conformity
-
You're shopping around for the cheapest option for a quick fix
-
Your team won't change the design, you want a workaround that avoids touching the designs
-
You don't have time for a proper review before your next fabrication run
-
You want someone to just get you through the test, with no interest in understanding why

Ways to Work With Us
OPTION 01 · SINGLE PROJECT
EMC Design Audit
€8,000
One-time payment · Results in 10 business days
This service is appropriate when a specific project is approaching a prototype manufacturing decision and requires a focused, customized review, without the need to establish an ongoing engagement. We analyse your design files, identify every electromagnetic risk, and hand your engineers a prioritised fix list they can act on immediately. Your team implements following our guidance. We're there to answer questions for the next 30 days.
WHAT’S INCLUDED
45-min kickoff call where we learn your product, your target standard, and your deadline before we touch any files
Full review of your board's EMC risks: layer stack, schematics, return current paths, power layout, and how multiple boards interact
Identification of noise sources on the board and exactly how that noise needs to be mitigated to avoid emissions
A prioritised list of issues with the most critical first, so your team knows what to tackle in what order
Specific fixes for every issue, written for your exact project, not a generic checklist
60-min debrief call where Dario walks through every finding and answers your team's questions
BONUS: 30 days of email support while your team implements the changes

This engagement establishes a dedicated EMC partner within your Company’s development structure. It operates with the continuity and integration of an internal function, maintaining direct collaboration and an ongoing understanding of your Company’s development stages, product architecture, and prior technical decisions. Unlike a conventional consulting model, the collaboration does not need to restart with each new project. Technical context is retained and expanded across programs, creating consistency and efficiency over time. The fee is fixed per engagement cycle and reflects reserved EMC review capacity rather than per-task billing. It does not fluctuate based on the number of design submissions, discussions, or correction loops. Your Company’s team collaborates directly with Dario within the defined engagement scope and allocated monthly capacity, without hourly tracking or administrative metering.
WHAT’S INCLUDED
Ongoing design reviews at any stage, including schematic, layout, stackup, full system, with specific written feedback every time you submit
Pre-test preparation so your designs are ready before they go to the lab, fewer surprises, higher pass rate
EMC checkpoints built into your development process with clear criteria your team can use to catch problems before they get expensive
EMC checkpoints built into your development process with clear criteria your team can use to catch problems before they get expensive
