Comprehensive EMC Resolution Roadmap: From Technical PoC to Full On-Site Compliance
- Step 1: Experience the Impact (Phase 2)
Experience a portion of Our Methodology through an affordable trial. Verify the dramatic improvement on your own hardware first. - Step 2: Achieve On-Site Success (Phase 3)
We visit your facility to implement all radical countermeasures and achieve rapid EMC Compliance — securing a rock-solid data foundation for the final stage. - Step 3: Maximize Product Profitability
In the final stage, we perform “De-tuning” based on your newly established design margins, eliminating redundant components to reduce your BOM costs (QCD).
Introduction
Our “On-Site Service” is structured into three systematic phases designed to achieve EMC compliance and cost optimization in the shortest possible timeframe.
To ensure a seamless collaboration, we provide full transparency regarding the scope of work, deliverables, fee structures, and payment methods for each process—from the initial free consultation to the final on-site resolution.
Prioritizing a relationship of trust with our clients, we move projects forward according to the following procedures.
Phase 1: Pre-Assessment Meeting
Please feel free to discuss anything—from questions about our services to the feasibility of resolving your specific EMC issue.
1.1 Initial Contact & Pre-Meeting Setup
Inquiry:
Please contact us via the contact form.
Scheduling:
We will reach out via email to coordinate a date and time for the web conference.
Preparation:
To facilitate a productive discussion, please email us clear photos of both the top and bottom sides of the target PCB prior to the meeting.
1.2 Meeting Agenda & Scope Alignment
Free Q&A
We will address any questions or concerns regarding our process.
Overview of actual “EMC Test Failures”
We will review the product overview and the details of your actual EMC test failures.
System Overview & PCB Configuration:
Understanding the board stack-up, external I/O, power supply methods, presence of isolation circuits, and the scope of firmware control.
Target Market Launch Date:
Confirming the project timeline and urgency.
Identification of Test Failures:
Specific names of failed tests and the total number of non-compliant test items.
History of EMC EMC Robustness levels:
• Details of added countermeasures and the resulting changes in EMC Robustness levels.
• Initial test results (the baseline of where the product passed or failed).
PCB Revision History: The number of prototypes and board revisions completed to date.
Review of “Design Data” availability
To ensure a smooth transition to the next phase (Diagnostic & Strategic Assessment), we will confirm the availability of specific design data, such as schematics, Bill of Materials (BOM), and PCB layout files.
If your design is outsourced, we understand that verifying access to these files or preparing them can often be time-consuming. Our primary objective here is to assess whether these documents can be ready by the project commencement. Please note that we will not delve into any specific design details at this stage.
1.3 NDA Policy & Confidentiality
As we do not perform detailed circuit analysis or exchange sensitive proprietary information during this initial meeting, we generally consider a Non-Disclosure Agreement (NDA) unnecessary at this stage.
Our rationale:
• No deep-dive discussion into specific circuit architecture.
• No financial transactions involved.
• No transfer of confidential technical documentation.
• PCB photos do not reveal proprietary details sufficient for misappropriation.
However, if your corporate policy requires an NDA to be in place, we will gladly accommodate your request and enter into an agreement.
1.4 Post-Meeting Evaluation & Formal Quotation
If we determine the issue is resolvable based on our meeting, we will issue a formal quotation for “Phase 2: Diagnostic & Strategic Assessment”.
Phase 2: Diagnostic & Strategic Assessment
Service Concept:
This service partially applies a key portion of our “Our Methodology (Fundamental Layout and Routing-Driven Noise Suppression)” methodology to significantly enhance EMC robustness at a minimal cost.
Since this trial plan implements Our Methodology only partially, it does not guarantee that your product will meet the EMC compliance limits. It is strictly designed for you to experience the high-impact effectiveness of our technical approach at an introductory price.
Full implementation of this Our Methodology is the ultimate goal of the remediation process and constitutes the scope of Phase 3.
2.1 Service Application & Scheduling
Application:
Please notify us of your intent to proceed with Phase 2 (Diagnostic & Strategic Assessment) via the contact form.
Scheduling:
We will coordinate the date and time for the web conference via email.
Pre-review of Terms and Agreement Process:
Before commencing the service, we will execute a formal “Consulting Services Agreement.”
To ensure maximum transparency and to facilitate your legal department’s review, we have made our “Standard Terms and Conditions“ publicly available on our “Business compliance“ page.
By reviewing these standardized terms in advance, you can streamline your internal approval process without waiting for the formal contract. We encourage you to use this resource for your internal pre-review and legal checks. The formal contract will be a bilateral agreement based on these terms, explicitly identifying you as the “Client” and us as the “Consultant,” to be finalized via electronic signature (DocuSign).
2.2 Onboarding & Contract Execution
The following four items are required to begin the service: [Ref: Article 2.4]
Issuance of Purchase Order (PO)
Please send your PO via email based on the quotation provided.
Execution of Service Agreement (Consulting Services Agreement)
We will facilitate the contract signing through DocuSign. The terms will be consistent with the “Standard Terms and Conditions” published on this site.
Payment
Please complete the 700 USD advance payment via Stripe (Credit Card) [Ref: Article 3.2].
Data Sharing
Please provide the following design documentation in digital format:
• Schematics
• Bill of Materials (BOM)
• Datasheets for each component
• PCB Layout Data (Native Files) *
• Further details regarding design documentation †
Viewing Environment:
We use free viewer software provided by major CAD manufacturers to conduct our detailed reviews.
Analysis Example:
We perform a rigorous end-to-end trace of critical signals, such as Reset or Write Enable lines cascaded from a CPU/FPGA to DDR or FLASH ROM, identifying their exact paths across all board layers.
Supported CAD Tools:
We support major global platforms, including Altium Designer, Cadence Allegro, and Siemens PADS.
Note:
As CAD types and versions vary significantly, please include a link to the recommended viewer software or its name when providing the data.
If Native Files Are Not Available:
In cases where native data cannot be provided (e.g., due to outsourcing constraints), please provide the following in PDF format as a minimum requirement.
To maintain analysis accuracy, all layers must be maximized to fill the full printable area of A3, Tabloid, or Ledger size pages at a consistent scale, ensuring high visibility with identical alignment based on registration marks.
Since we overlay and look through each layer to trace the routing and patterns, any variation in scale or misalignment between layers will make precise analysis impossible.
• Copper Layers (Pattern drawings for all layers)
• Solder Mask Layers
• Silkscreen Layers
• Board Outline (Mechanical/Profile drawing)
• Drill Drawing (Map of all holes and vias)
To refine our analysis, please provide the following specific:
• Current Consumption (Typ) of Major ICs
• Duty Cycle of Digital Signals and Communications
We need to understand the “frequency of occurrence” (timing and duration) rather than just the clock speed.
• Fixed Design Constraints (Non-modifiable areas)
1. Areas where IC manufacturer-recommended circuits must be followed (e.g., USB, Ethernet-to-RJ45).
2. Standardized circuit modules used across multiple products that cannot be altered.
Access to your “Design Specifications & Rationale” covering these points is highly appreciated.
This refers to documentation that captures the detailed “intent” behind your design choices. It may also be called a Basic Design Document, Detailed Specification, Technical Document, or Internal Spec.
Specifically, this refers to documentation that records the process behind your design decisions, such as the following:
Examples include:
Ex 1: Selecting Electrolytic Capacitors for Power Supply Primary Sides
The reasoning behind the specific capacitance (e.g., 10uF).
Why a specific voltage rating (e.g., 16V) was chosen.
Why an 85°C temperature grade was selected instead of 105°C.
Ex 2: Determining Current-Limiting Resistors for LEDs
The calculation leading to the resistance value (e.g., 560Ω).
Why a power rating of 0.1W was selected.
The reason for choosing a specific tolerance (e.g., J-grade).
Ideally, these details should be formalized in a Technical Design Review (DR) document once the schematics are complete. However, having personally navigated dozens of high-pressure projects, I know all too well that formal documentation often takes a backseat to urgent prototyping and component sourcing.
There is absolutely no need to reformat your notes for me. As long as the designer’s “intent” is clear, I can read it from anything—be it handwritten notes, rough conceptual sketches, or even “back-of-the-envelope” calculations.
As fellow engineers, these “living traces” of your thought process often communicate more than any formal report ever could. Please do not worry about the format; simply share the raw insights you have on hand, whether they are rough sketches or basic diagrams.
2.3 In-depth Analysis & Technical Interview
Upon receipt and review of the required documentation, we will conduct a detailed interview to refine the resolution strategy.
In-depth analysis of actual “EMC Test Failures”
We will identify the physical phenomena behind the failures through:
EMS (Immunity):
Specific behavioral malfunctions in response to “test stress” (such as electrostatic discharge or electromagnetic fields).
EMI (Emission):
Spectral distribution and peak frequency characteristics of radiated emissions (e.g., noise spikes in the 200MHz or high-frequency bands).
Performance Criteria & Definition of Malfunction:
Re-confirming the specific “EMC compliance limit (pass/fail threshold)” and the “Definition of Malfunction” for your product.
In principle, we follow your internal “Definition of Malfunction.” To ensure a clear understanding of the conditions for achieving EMC Compliance, we will discuss and reach a consensus on the following Pass/Fail Thresholds in advance.
Typical Examples of Malfunction (for reference):
• System Reset: Whether a reset event is judged as a “Fail,” even if followed by automatic recovery.
• Display Abnormalities: Screen freeze, or noise/flicker that significantly impairs visibility.
• Audio Anomalies: Abnormal sound output or noise exceeding acceptable levels.
• Peripheral Malfunction (Printers, etc.): Unintended paper feeding (continuous discharge) or loss of control.
Optimization of Criteria (Avoiding Over-Engineering):
In special cases where definitions are ambiguous, we will establish a realistic consensus by referring to international “Performance Criteria” and market precedents.
Note: This is a rational measure to avoid “over-engineering” caused by excessively rigid criteria, preventing the waste of development time and costs. We aim to define the EMC Robustness that is appropriate for your specific product.
Detailed review of “Design Documentation”
Upon receipt of all required data and completion of the advance payment, we will officially initiate a dedicated 1-week investigative analysis phase to independently audit, analyze, and thoroughly evaluate your schematics and layout topology.
If necessary—solely to resolve any gaps, structural ambiguities, or unstated layout intents within the provided data—we may initiate a focused technical Q&A with your team flexibly via email or a web conference. Otherwise, we will proceed directly with our deep architectural analysis.
2.4 Report Analysis & Delivery
Once all required data and documentation have been completely provided, we will conduct an in-depth analysis to identify the specific “pathological areas” hindering your EMC compliance.
Lead Time:
Assessment is typically completed within 7 business days.
Review Meeting:
We will hold a web conference to present the Technical Assessment Report, detailing one specific, high-impact modification and explaining the underlying physical phenomena.
Please note that the 7-business-day lead time does not include the duration of this Q&A period (until all documentation ambiguities are resolved).
2.5 Trial Implementation & Feedback Loop
Please apply the recommended modification based on the Technical Assessment Report to your target PCB and share the baseline evaluation results with us.
This feedback is a critical step to maximize the feasibility and success rate of Phase 3 (Intensive On-Site EMC Troubleshooting for Compliance).
2.6 Preliminary Quotation & Next Steps
Based on the verification results, we will provide a Preliminary Quotation for Phase 3.
Note: This will be an estimated quote as the specific on-site destination (your company’s development lab, etc.) is typically yet to be determined at this stage.
2.7 Delivery Deadline & Refund Guarantee
To ensure a professional and transparent engagement, the following policy applies to the Diagnostic & Strategic Assessment: [Ref: Article 7.4]
Eligible for Refund: Delivery Delay:
If the report is not delivered within 7 business days from the “Analysis Start Date” (the date all required materials are confirmed to be sufficient), I will refund the full fee plus a 20% penalty. This is my commitment to integrity and professional speed.
Non-Refundable: Test Results & Outcomes:
This service is consideration for the provision of expert diagnostic insights. I do not guarantee specific test outcomes or noise reduction levels, as these depend on the physical state of your hardware. Once the report is delivered, no refunds will be issued regardless of subsequent test results.
Phase 3: Intensive EMC Troubleshooting
“One-week on-site support to achieve full compliance with guaranteed expertise.”
In this phase, we implement every strategic architectural modification to maximize your product’s EMC robustness. I will provide intensive, hands-on on-site support at your facility for a strict, finite duration of approximately one week, executing rapid experimental iterations to maximize your compliance margin within this single, dedicated execution window.

Full list of non-compliant test items:
Essential for determining the priority and methodology of countermeasures.
Results of voluntary countermeasures:
Updates on any measures implemented since Phase 2 and their effectiveness (required to calibrate the intensity of proposed modifications).
Itinerary Coordination
A one-week stay is typical; however, the final duration will be optimized based on travel time, system complexity, and the total number of test items, as specified in the Final Quotation.
3.3 Fee Structure & Final Quotation
Based on the discussions during the On-Site Alignment, we will provide a Final Quotation that includes the total number of failed test items, the planned itinerary, and daily consulting fees. The breakdown of the fee structure is as follows:
Success Fee
This fee is payable only upon achieving the project objective (Compliance). [Ref: Article 3.3]
Base Success Fee:
5,000 USD (for the successful passing of one primary test item).
Additional Test Item Fee:
If there are multiple non-compliant test items, an additional 1,000 USD will be added for each subsequent non-compliant test item successfully passed.
Example: Passing a total of 3 non-compliant test items = 5,000 + (1,000 × 2) = 7,000 USD.
Payment Method:
A “Credit Card Authorization (hold)” via Stripe will be required prior to departure. [Ref: Article 3.4]
Daily Consulting Fees
These fees cover the expert’s time and on-site engagement. [Ref: Article 3.2]
