Conformal coating (CC) is widely used to protect printed circuit board from corrosion, mold growth, and electrical failures. To ensure effective protection, the thickness of the CC layer needs to be well controlled. However, to date, the coating thickness is usually measured in a destructive way under microscopes. In this paper, we proposed to use optical .DOI: 10.1109/ACCESS.2019.2896622 Corpus ID: 67866968; Nondestructive Measurement of Conformal Coating Thickness on Printed Circuit Board With Ultra-High Resolution Optical Coherence Tomography The main characteristics of Acrylic-based conformal coatings are their low cost and ease of application making them ideal for hobby electronics. You can apply this coating using various techniques, including dipping, spraying, or brushing. . Another consideration for coating thickness is the thermal expansion coefficient. This parameter will .The typical thickness of the conformal coating is 1-5 mils. There are three ways to measure the thickness of conformal coating: Wet film thickness gauge; You can measure the film thickness using a gauge with teeth and notches. Each of these teeth has a calibrated length. Placing the gauge into a wet film measures the thickness of the conformal .
This manual method is cost-effective for low-volume production as it requires minimal tooling. Even if masking jigs are needed, they don’t have to be highly precise. However, the coating can be inconsistent due to operator skill or fatigue, and brush hairs may shed. . Measuring Conformal Coating Thickness.

What Is Parylene Conformal Coating? Composed of selected chemicals or polymer films, conformal coatings provide protective substrate coverings for all kinds of products. In addition to parylene, the substances acrylic, epoxy, silicone and urethane are most commonly used for conformal coating today. They can be simply applied to substrates — by . The thickness measurement process entails placing the test probe head flat onto the surface of the conformal coating, and the measurement results are nearly instantaneous. The measurements are highly accurate and non-destructive, provided that there is metal present directly beneath the tested point on the circuit board.
