New from Nordson ASYMTEK is Select Coat SC-350 select spray applicator for conformal coating applications. It delivers enhanced edge definition and uniform coating thickness at high speeds while accommodating a wide range of fluid viscosities. This ensures tight keep-out zones and enables thin film builds, which are critical in automotive and mobile electronics device manufacturing and assembly.
SC-350 is ideal for applications that require precise edge definition and uniform passes for 100% solids as well as solvent-based materials. An innovative airflow extension optimises atomisation of high-viscosity materials, such as silicones, acrylics and urethanes, and reduces the cobwebbing effect that occurs when coating materials cure in air. Viscosities ranging from 30 cps to more than 3500 cps can be handled efficiently while reducing solvent use.
The applicator is designed for use with the Nordson ASYMTEK SL-940 conformal coating system. It supports the four-position tilt accessory that features the standard vertical position and tilts the applicator at 30 degrees in four positions to spray all four sides of a part and areas not accessible from the standard vertical orientation. It also adapts to the dual-simultaneous configuration that reduces process time by 50%.
The SC-350 applicator is easy to clean and maintain, with minimal wetted parts, smooth internal surfaces and exposed splines. Cost efficiency is realised through minimised fluid and solvent use as a result of thinner film builds, while exacting keep-out zones save fluid, repair and rework.

Editor's Choice Manufacturing / Production Technology, Hardware & Services
Dross formation is an inevitable consequence of wave soldering. It occurs when molten solder comes into contact with oxygen, forming metal oxides that float on the surface of the solder bath. Over time, this oxidation byproduct accumulates and must be removed to maintain solder quality and process consistency.
