The Nordson ASYMTEK FX-940UV series makes the inspection of conformal coatings easy and
convenient by automating the inspection process for coating quality and consistency.
Conformal coatings used by electronics manufacturers contain UV indicators for inspection purposes.
Since coatings are transparent, the workpieces must be viewed under black light to check for coverage and non-coverage.
Advanced high-performance UV illumination and newly available image processing technology integrate multiple techniques,
including coverage verification, color verification, normalized correlation and
rule-based algorithms to achieve full inspection coverage with an unmatched low false error rate.
With minimal programming effort, the test setup is fast and intuitive and usually takes less than 30 minutes.
A well-known good board is used to learn the coverage and non-coverage areas.
The automated inspection typically takes only a few seconds and the inspection results are displayed immediately.
These results can be saved and reviewed offline.
The FX-940UV also reads all common barcodes and records logs for product traceability.
