摘要：

The article presents a research focused on printed circuit board protective coatings as an option for the assembled PCBs cover and electronic device reliability improvement. The experiment with different coatings is described in this article. For the experiment, rigid substrate (FR-4) is used. The protective coatings from acrylic, urethane, silicone and fluoropolymer materials were used. The differences in substrates and coatings have an effect on the insulation resistance which was measured by SIR test. The samples were exposed to accelerated aging test by increased voltage. The advantages, disadvantages, comparison and results from measurement are discussed in this paper. The results present the comparison of the tested conformal coatings. The importance of cleaning before application of coatings is the next part of results.
