INDUSTRIES / AUTOMOTIVE & EV

Put every end-of-line result in context.

Connect controller programming, interface checks, and final functional tests to the same serial number. Compare vehicle variants, software revisions, and production stations without losing the original test evidence.

Electric car beside a control module and electric drive assembly

Compare the right variant.

Keep part configuration and software revision beside the controller’s test version.

Follow the supplier part.

Link incoming boards and modules to their finished assembly.

Keep first-pass yield visible.

Preserve initial failures when rework or a retest produces a pass.

WORKFLOW EXAMPLE

Follow a controller from programming to end-of-line test.

An illustrative controller workflow combining configuration checks, interface measurements, and yield review across equivalent production units.

Line resultsFirst-pass yield

Compare controllers with the same variant and software before investigating a yield change.

Program and record
Keep the controller serial, hardware variant, and programmed software identifier with the run.
Check the interfaces
Record bus communications, I/O responses, and supply-current measurements on the bench.
Review line performance
Compare first-pass results by station and variant, with individual failed runs available to inspect.

ALERT & NEXT STEP · EXAMPLE

First-pass yield has dropped against the procedure’s recent baseline.

Open the affected runs with the production engineer. Compare station, supplier batch, and software revision, then agree the next diagnostic check and any containment decision.
