Graham, I don't know if you are automatically or manually spraying. For automatic spraying, we've installed precision flowmeters. The volume dispensed data is compared to tolerance limits set in the programmable controller by the spray routine. The machine alarms if the assembly is coated out of tolerance and corrective action can be taken immediately by the operator - before the material is cured. We also capture the data in our quality management database for trend analysis purposes.

I've got a question for the conformal coaters out there. Our situation: We currently measure CCA thickness before application, and then again after application & cure of conformal coating, to determine how thick a coating we have applied. We are currently using a micrometer to measure the thickness. Our coating thickness is in the 0.001" to 0.005" range. My question is: what are others using to do this sort of measurement? Are there are better tools out there to do this faster / better?
