Summary
| Description |
English: Measurement of the conformal coating thickness after application can be completed once the coating is dry enough to handle and a hardness is achieved using a non contact technique using eddy currents. A system like the Positest from SCH technologies is extremely quick and accurate to ±1 um at thin films of 25-50 um.
Placing the test probe head flat on the surface of the conformal coating, the measurement is almost instantaneous and provides an immediate repeatable result for thickness measurement of conformal coating. Test coupons are the ideal method for measuring the coating thickness, whether is it spraying or dipping, and can be kept as a physical record of the performance. Apply the coating to the test coupons at the same time as the circuit boards provides a permanent measurement and an accurate guide to the coating thickness. |
