Follow a build through the facility
A useful facility review connects incoming materials to the delivered board. Ask the host to explain how a released revision becomes a production job, how materials are identified, and how completed operations are recorded. This is a preparation guide for a supplier visit, rather than a claim that the photographs on this website show a particular factory.
Questions for the production walk-through
- Receiving: how are component identity, condition and discrepancies recorded?
- Preparation: how are approved files, tooling and programs kept at the correct revision?
- Assembly: how are paste printing, placement and soldering processes controlled?
- Inspection: how are defects identified, dispositioned and retested?
- Shipment: how does the final record link to the physical lot and accepted requirements?
Request evidence rather than relying on appearances
An orderly production floor is useful context, but it does not establish performance for your construction. Review representative records, the scope of any certificates and the process for handling nonconformances. Agree which areas and records can be reviewed before a visit so confidentiality restrictions do not prevent the intended assessment.
Turn observations into decisions
Record each finding, its relevance to the proposed build and the evidence needed for closure. Distinguish an improvement suggestion from a requirement that must be resolved before qualification. Keep the review with the supplier approval and the quoted manufacturing scope.
