PERSPECTIVE
Control points should follow risk
Materials and processes carry different risks. Incoming checks examine inputs; process control covers assembly and critical parameters; whole-device checks look at function and record completeness. Each point needs a defined acceptance basis.
When a deviation appears, affected items should be identified and facts recorded before impact and disposition are decided. Feedback after delivery also matters: some issues only emerge in a particular use context.
KEY AREAS
From principle to practice
Process and device
Record results at key assembly and function points, identifying deviations.
Release and feedback
Review required records and return post-delivery issues to the improvement loop.
HOW IT WORKS
Traceability makes improvement specific
A useful process records more than “pass” or “fail”. Batch, test conditions, symptoms and decisions make it possible to find patterns and improve design or production methods.
- Confirm input and control criteria
- Inspect and record deviations
- Review results and later feedback

Frequently asked questions
What are the quality control checkpoints?
Aesthetic device quality control is organized around five checkpoints: incoming material, process, whole-device, release and post-delivery feedback.
How are nonconformities handled?
Deviations are recorded with test conditions and disposition decisions, then reviewed so corrective actions feed back into design and process.
Are test records available to customers?
Batch-level test summaries can be provided to partners with shipments or during audits, per agreement.
