Testing and QA for Radar Detector Orders

Testing on an electronics order is planned before production, not improvised after it. This page describes the stages and the records, so a buyer knows what to ask for and when.

Incoming components

Before assembly, key components are checked against the approved bill of materials: supplier certificates, a visual check, and a sample functional check. The record is an incoming check sheet per lot. Ask whether the bill of materials is frozen after sample approval, and how a component change is notified.

In-line checks

During assembly, the line checks first pieces at each shift start and records the results in a line log. Electronics assembly problems found in-line cost a fraction of what they cost at final inspection, so ask how often first pieces are checked and who signs the log.

Functional test

Each unit, or a documented sample from each run, is powered and tested against the SKU specification: power-up, reception, alert display, audio, and the controls. Confirm whether testing is per unit or per sample, and ask for the test record format. A test report for the ordered SKU is part of the shipping document set.

Final inspection

Finished units are inspected for condition, labels, firmware version, and accessory count against the packing list. Sampling plans and acceptance limits are agreed in writing before production starts. The final inspection report lists the sample size, findings, and the decision.

Packing check

Carton marks, counts, and the packing list are checked before the goods leave. A mismatch found at the factory is an email; found at your warehouse it is a claim.

What to ask for

• The inspection plan for your order, in writing, before production.
• The test record for your SKU, with the shipment.
• The firmware version recorded per production run.
• Notification in writing for any change after sample approval.

None of these records needs to be long. Short, dated records that name the SKU are worth more than a thick general quality manual.
