Specify the requirement before comparing suppliers
Manufacturing capability is a combination of material, geometry, process and acceptance criteria. A single minimum feature or maximum layer count does not describe whether a supplier can build your particular construction reliably. Use the checklist below to request a project-specific capability review.
| Area | Define in your package | Confirm during review |
|---|---|---|
| Construction | Rigid, flex, rigid-flex, layer count and stack-up | Available material system and approved construction |
| Geometry | Trace/space, finished holes, vias and tolerances | Production design rules for that construction |
| Copper and finish | Finished copper, surface finish and special contacts | Process compatibility and acceptance criteria |
| Assembly | Package types, both-side population and special operations | Placement, soldering, handling and inspection route |
| Sourcing | Exact parts, approved alternates and consigned material | Availability, traceability and shortage approvals |
| Testing | Electrical tests, functional tests and coverage | Programs, fixtures, reporting and exclusions |
Ask for evidence that matches the build
Where certification or qualification is required, request current documents with the applicable scope and facility. Where a design pushes a process limit, ask for an engineering review and a suitable qualification or first-article plan. This page is a specification checklist, not a claim that every listed process or tolerance is available.
