UV LAMPS PCB inspection for conformal coating validation

UV-A blacklights are used for inspection of conformal coatings on printed circuit boards (PCBs) to check for uniform coverage.

UV blue tracer additive is incorporated within the formulation of the coating and glows bright fluorescent blue under UV blacklight. Any areas on the PCB not glowing reveals parts missed during the application of the coating e.g. conformal coatings on electronic circuitry for environmental protection and corrosion resistant metal coatings.

We offer a wide range of UV blacklight inspection lamps utilising both high intensity discharge (HID) bulbs and low pressure (LP) tubes from hand lamps and torches to large area flood lamps for checking the uniformity and correct location of conformal coatings.

Selection of UV light equipment should be optimised for a particular application and depends on the requirements for UV light irradiation area, UV light intensity, process integration, ambient light levels and temperature sensitivity.

Our luyor® technical solutions combine equipment selection recommendations with health & safety training and products. This ensures maximum performance benefits, safe use and confidence of the workers.
