69 VALVE APPLICATIONS APPLICATION DEFINITIONS Microdots: Any deposit having a volume less than 5 μl (5 μl = 5 microliters = 5/1000 cc). Dots: Any deposit having a volume larger than 5 μl. Potting: Filling a cavity usually containing an electronic device, electronic circuit or wires. Encapsulating: Applying a coating to an electronic component for protection from mechanical or environmental damage. Lines: A line, bead or stripe of material. Filling/Packaging: Filling containers such as small bottles, cartridges and tubes. Spray: Applying fluids using low pressure air to break the fluid into fine droplets for coating or marking. Internal Spray: Spraying the inside diameter of holes and cylinders.
