Nordson ASYMTEK Intros Jet Fluid Dispensing
Jet fluid dispensing system.
Carlsbad, CA — Nordson ASYMTEK is introducing jet dispensing for manufacturing side-view LEDs. The system jets 0.1 to 0.2mm dots through windows as small as 0.4mm into the LED cavities of side-view LEDs that illuminate the displays in devices such as tablet computers, smart phones, and e-readers.

The new Spectrum S-920N jetting system automatically maintains a consistent shot weight with software-managed dispense parameters. Closed-loop dispensing eliminates the need for time-consuming operator adjustment. Unlike other multi-headed needle dispensing systems, the new system is easier to set up and maintain in production, keeping process under machine control.

According to the company, consistent dispensing weight improves process capability while ensuring higher UPH (units per hour). Using CPJ+ (calibrated process jetting plus), the process variability is reduced for tight LED color quality. This patented, technologically advanced software and hardware control reduces process variation, increases yield, and reduces cost.

The system uses a jet for non-contact dispensing. Unlike a needle, the jet retracts much less for silicone break off and therefore shoots multiple shots faster, increasing speed and throughput. The jet's small, controlled drops of fluid reach tight cavities consistently and reliably, unlike needles which have orifices larger than the cavity windows of side-view LEDs.
