AOI, X-ray, in-circuit test and functional test examine different failure modes. Identify what each method can miss rather than assuming one test replaces the others.
Match defect coverage to product risk
Use the requirements below to prepare a focused project review. Confirm the work scope, acceptance criteria and responsibility for engineering changes in writing before production is released.
Information to include in your RFQ
- Netlist and accessible test points
- Expected measurements and limits
- Fault reporting and serial-number format
Compare proposals on the same scope
Separate recurring unit cost from tooling, setup and test-development charges. Check what is included in inspection, traceability, packaging and disposition of nonconforming units. Ask which assumptions could change the quoted price or schedule.
Capability confirmation
[NEEDS CLIENT INPUT]: approved process capabilities, equipment, certificates, MOQ and available production lead times for this service.
These requirements describe a purchasing and engineering review, not a verified statement of factory capability.
