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. Jetting: Applying microdots, dots, lines, stripes, and encapsulates without making contact with a surface — also called noncontact dispensing. 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 / Stripes: A line, bead or stripe of material. Filling / Packaging: Filling containers such as small bottles, cartridges, and tubes. Microspray: Narrow spray pattern capability as small as 1 mm (0.04") wide. Spray: Applying fluids by 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.
