Making devices at volume.
WHAT CHANGES AT VOLUME
Assembly cost matters Testing must be fast Component cost differences multiply Consistency becomes a problem
WHAT DESIGN FOR MANUFACTURE MEANS
Designing so the product can be built reliably and economically.
WHAT IT INCLUDES
Minimising component count and variety Avoiding manual assembly steps Making orientation unambiguous Providing test points
WHAT PRODUCTION TESTING MUST VERIFY
That the device powers on That every peripheral functions That the radio transmits at expected power That credentials were provisioned
WHY PROVISIONING TESTING MATTERS
A device shipped without valid credentials cannot connect and must be returned.
WHAT TO AUTOMATE
The test, so it takes seconds per unit.
WHAT TO RECORD PER UNIT
Serial number, test results, and firmware version.
WHY
It enables tracing a fault back to a batch.
WHAT BATCH TRACEABILITY PROVIDES
The ability to identify affected devices when a component or process problem emerges.
WHAT TO PLAN
Rework and failure rates.
WHAT TO ESTABLISH WITH A MANUFACTURER
Quality expectations Test procedures What happens to failures Ownership of designs and tooling
WHAT TO VISIT
The line, before committing.
