    TECHNICAL ARTICLE: Conformal coatings are protective lacquers used within the electronics industry to protect printed circuit boards (PCBs) and eliminate failures caused by exposure to a variety of environmental conditions. Such conditions can include airborne ionic material, atmospheric moisture and the electrostatic attraction of dust. In more challenging environments however protection from chemicals, extreme humidity or even corrosive atmospheres, such as salt mist, may be required. The coatings are designed to ‘conform’ to the contours of the board, protecting all areas to which they are applied and thereby extended the working life of the PCB.
