Thickness metrology for medical patch coating
Non-contact thickness monitoring was required where coating area and coating uniformity are critical.
Solution
UniEye applied optical thickness metrology matched to material characteristics and measurement range to monitor coating-layer deviation.
Outcome
The system enabled quantitative management of coating-thickness deviation and provided evidence for process quality control.
Implementation points
- Non-contact thickness measurement
- Coating-area and uniformity monitoring
- Recipe-based process changeover
- Quality-control data provision
Feasibility for similar processes can be reviewed using sample images, defect types, line speed and inspection width.
