Quality starts with the release package
Inspection cannot resolve an ambiguous requirement. Confirm the approved drawing, BOM, revision, applicable acceptance criteria and any special conditions before production. Record deviations and customer approvals in the build package.
If your order requires a particular IPC class, standard revision or customer specification, state it explicitly and agree on the inspection and documentation needed to demonstrate conformity.
Choose methods that answer different questions
- Bare-board electrical test checks connectivity against the intended netlist; it does not validate the end-product function.
- Optical inspection can identify visible workmanship or placement issues but does not see every hidden solder joint.
- X-ray inspection can support evaluation of hidden features; interpretation and acceptance criteria must be defined.
- In-circuit and functional tests exercise different parts of the assembly. Coverage depends on the design, access and test program.
- Environmental or reliability testing needs defined conditions, sample size, duration and acceptance limits.
Request the documents your team needs
Identify required inspection reports, electrical-test records, material evidence, component traceability, lot identification, test logs and certificates of conformity at quotation stage. Not every document is automatically included in every build.
For first-article approval, agree on which measurements and records must be reviewed before the remaining quantity is released.
Qualify the supplier for the application
Request current certificates and verify the legal entity, covered site, scope and expiry where certification is mandatory. Equipment lists and process descriptions are useful evidence of capability, but they do not establish certification by themselves.
Report a quality issue with the order reference, affected quantity, board revision, photographs or measurements and the conditions under which it occurs. Preserve the evidence so the cause and corrective action can be investigated.
