Quick and Easy Measurement for Process Control
Wet film thickness measurement is a quick, reliable and low-cost way to control conformal coating application while it is still wet. By checking coverage before curing or drying, operators can spot issues early, make immediate adjustments, and prevent costly mistakes.
This simple check helps teams reduce waste, improve accuracy, and keep application consistent from start to finish.
Why use a wet film thickness gauge?
- Real-time feedback during spraying or brushing β adjust technique immediately
- Avoid over-application to control cost, weight, and coating performance
- Reduce scrap and delay where dry measurements are difficult or destructive
- Support process control for prototypes, engineering runs, and production lines
How it works
Place the gauge directly onto the wet coating so the stepped teeth touch the film. Read the first tooth that makes contact to capture the wet film thickness.
To estimate dry film thickness, multiply the wet reading by the coatingβs resin-solids percentage. Because the method takes seconds, operators can keep coatings within target without waiting for cure or using destructive methods.
Optional support
SCH can support you with coating process setup and operator best practice, including film build targets, measurement technique, and inspection workflow integration.
Tip: Wet film gauges are ideal for fast checks during application. For cured thickness verification on witness coupons and suitable PCB locations, see the Positector 6000.
