Asymtek has introduced the SC-400 PreciseCoat conformal coating jet for applying coating materials to highly selective areas, especially on small substrates or those with high-component density, where there are tight tolerances between coated and uncoated areas. With the jet the need for masking is virtually eliminated because delivery of the coating is so accurately controlled. Using a needle design with non-contact jetting action and fast pulse-width modulated control, the jet delivers conformal coating to areas not accessible by other applicators. Small volumes and precision control of the conformal coating material enable line widths down to 1.2 millimeters (0.05 inch) wide. Film thicknesses of 15 micrometers are achievable when using solvent-based materials. Acrylics, silicones, urethanes, UV-cure and water-based materials with a viscosity range of 1 to 850 centipoise (cps) can be jetted.
The Jet provides flexibility for many diverse conformal coating applications in industries such as automotive, commercial, avionics, military, and the medical market. Multiple dot sizes can be delivered from the same applicator, yielding small volumes with good volume control. A dual-valve configuration is available when the operation requires coverage of a large area in addition to precision conformal coating. The jet is designed to be used on the company’s Century Series conformal coating systems, providing consistent uniform dispensing of a variety of conformal coating materials for both batch and inline coating applications.
