Share the non-negotiables
Identify critical tolerances, approved parts, operating conditions and mandatory documentation. Distinguish requirements from preferences.
Explore fabrication, assembly and verification requirements in one place. Use the matrix to prepare the information our team needs to evaluate your project.

| Area | Project requirements | Useful supporting information |
|---|---|---|
| Board constructionfabrication | Layer count, thickness, copper, material | Fabrication drawing + stackup |
| Vias & mechanicsfabrication | Drills, via structure, routing and tolerances | Drill data + dimensioned drawing |
| Surface & panelizationfabrication | Finish, solder mask, panel and fiducials | Fabrication and assembly requirements |
| SMT & mixed assemblyassembly | Populated sides, packages, leaded parts | BOM + placement data |
| BGA / fine-pitchassembly | Package requirements and hidden-joint review | Part datasheets + assembly drawing |
| Sourcing & inventoryassembly | Turnkey, partial turnkey or consigned | Approved BOM + supplied stock list |
| Programmingassembly | Device, firmware revision and sequence | Programming file + instructions |
| Inspectionquality | Visual / AOI, X-ray scope as applicable | Acceptance criteria |
| Functional verificationquality | Fixture, power, test sequence, pass/fail limits | Approved test procedure |
| Records & deliveryquality | Traceability, reporting and packaging | Required deliverables list |
This is a project review guide, not a universal specification limit. Final tolerances, process availability, standards and test coverage are confirmed in the quotation.
Technical limits only make sense alongside the material, geometry and acceptance criteria.
Identify critical tolerances, approved parts, operating conditions and mandatory documentation. Distinguish requirements from preferences.
Review sourcing constraints, manufacturability questions and proposed process changes before releasing files.
Confirm boards, programming, test results, documentation, packaging and shipment requirements in the approved scope.
Send the drawing, stackup or part datasheet with the inquiry. The team will assess the combination of requirements rather than infer support from an isolated number.
They answer different questions. Inspection checks assembly features; functional testing follows a defined procedure to evaluate product behavior. Specify the coverage you require.
List the exact standard, documentation and traceability requirements. Have the team confirm the applicable evidence before ordering.
Upload your manufacturing files and tell us which requirements need engineering confirmation.
