TEST ENGINEERING / ACCEPTANCE

Functional Testing

Translate expected electrical behavior into a defined test protocol, fixture scope and acceptance record.

Write the test around the expected response.

The protocol should explain what is applied, what is observed and how the outcome is assessed.

Conditions: Specify the required supply, operating mode and setup conditions.
Inputs: Identify the signals, commands or actions applied to the assembly.
Outputs: State the behavior or measurement that the test needs to observe.
Acceptance: Provide limits, references and a clear treatment of unexpected results.

THE TEST INTERFACE

Fixture and software responsibilities affect what can be verified. Resolve them alongside the board design, not after assembly.

A result needs enough context to show what was tested and under which agreed conditions.

Version: Assembly revision, protocol revision and relevant software identifiers.
Outcome: The required pass/fail decision or measurements, matched to the agreed criteria.
Exceptions: An identified review path when results fall outside the expected conditions.

AFTER A CHANGE

Rework, component changes and final integration can change the test context. Agree when re-verification is needed and what records accompany it.
