Electronics

With the increase in global demand for smart devices, AI-driven devices, digital health, connected medical devices and 5G technology UV products play an important role in ensuring quality of electronic components such as printed circuit boards, semiconductors, microchips, resistors, capacitors and other essential parts that require inspection and conformal coating validation to ensure the coating effectively protects electronic components from environmental factors. The coating also protects the components from contaminates such as solvents, chemicals, corrosion, mould and dust.

UVA blacklights are used to inspect colourless conformal coatings (coatings applied to electronic components) to ensure even coverage, thickness, adhesion and to check for voids, pinholes, insufficient coverage or areas where the coating may not have adhered properly or well enough. This is particularly important when compliance with industry standards such as IPC-CC-830 and UL746E are the benchmarks for performance and testing.

UVA fluorescent materials or pigments are often added to coatings to enhance their visibility under the UVA light, making the visual assessment easier to check the uniformity and quality of the coating. These are particularly useful when validating clearcoats on printed circuit boards.
