EMC engagements for every stage of development
Most projects use one or two steps. Pick the ones that match where you are today.
- Architecture Review
- Layout Review
- Layout Remediation
- Pre-Lab Test Strategy
- Lab
- Failure Analysis & Mitigationif needed
- Best when
- Before routing is complete (some placement and routing may be done).
- What we need
- Schematic, BOM, board outline. Helpful if you have: product requirements, current board design, enclosure concept, designer notes.
- What you get
- Stackup and placement guidance, constraints, and a risk memo.
- Follow-up
- Review meeting.
- Typical turnaround
- Starts at 2 business days.

Layout Review
Catch return-path, grounding, and decoupling problems before fabrication.
Start with this step- Best when
- Before design lock.
- What we need
- Schematic, BOM, Gerbers. Helpful if you have: product requirements, enclosure design, designer notes, test results.
- What you get
- An annotated report with fix recommendations.
- Follow-up
- Review meeting, and a board review after fixes.
- Typical turnaround
- Starts at 3 business days.

- Best when
- After a layout review or failure analysis.
- What we need
- The layout review and your design package.
- What you get
- Applied fixes, a change log, and residual risks.
- Follow-up
- One revision included, plus a review meeting.
- Typical turnaround
- Starts at 3 business days.

Pre-Lab Test Strategy
Walk into the lab with a plan built around your real operating modes.
Start with this step- Best when
- Any point in development.
- What we need
- Product description (operating modes and levels), product requirements, 3D models or images.
- What you get
- A test plan.
- Follow-up
- One revision included, plus a review meeting.
- Typical turnaround
- Starts at 5 business days.

Failure Analysis & Mitigation
Find the root cause and fix it with a targeted change.
Start with this step- Best when
- After a test failure.
- What we need
- Test results, schematic, BOM, Gerbers, enclosure design.
- What you get
- Root-cause analysis, corrective actions, and follow-on test planning.
- Follow-up
- Review meeting.
- Typical turnaround
- Starts at 3 business days.

- Best when
- Any time during development or project planning.
- What we need / what you get
- Varies. Tell us the question and we’ll scope it.
