Micro-Line digital dispensing valve, for the Prism coating system, is reportedly much more effective than conventional needle dispensing. Consists of a high-speed liquid metering valve and a precision nozzle. Applies conformal coatings in precise lines or dots as small as 1 mm with the liquid flow rate set electronically. Is applied at a distance from 5 to 15 mm above the board for accurate coating on all substrates.
