Test Intake / DUT Test Scope
Define targets and assumptions before design:
- DUT part number and revision
- DUT dimensions
- Required tests
- Test time: under 4 minutes
- Environmental requirements
- Acceptance criteria
- Required customer inputs
Test Requirements Specification
Lists all Customer Requirements, derived System Requirements, and resulting Test Requirements (what the tester must verify). Optionally Test System Requirements (what the tester must be capable of)
Test procedure specification
Describes the test flow in high-level pseudocode.
Test Design Specification
- Mechanical design
- Electrical design
- Electrical interface
- Instrumentation
- Calibration/self-test
- Spare parts
- Supported DUT revisions
Validation protocol + report
Defines what will be checked. The report records what happend. For example:
- Remove testing pins to simulate 0V on power pins
- Short testing pins to simulate short-circuits or excessive load.
- Test known bad boards
Operator instruction
Instruction for the operator on how to setup and execute the test:
- fixture photo
- DUT orientation
- barcode/serial scan step
- instruments/external tools
- start button
- pass/fail indication
- what to do on fail
- when to call test engineering
- cleaning instruction
- common failure messages
Maintenance guide
- Daily
- On start/end of batch
- Yearly
- After 10.000 cycles
