Leading Electronic Hearing Device Manufacturer Reduces Precise Coating Cycle Time by 79% With Advanced Nordson Automation

In this manual electromechanical assembly (EMA) application, operators hand-brushed protective UV coating material onto hearing device components on a double-sided printed circuit board with five precise coating areas on one side and four on the other. Components in each coating area were fully encapsulated with Dymax Multi-Cure^® 9-20557 medium-viscosity coating material, protecting them from moisture, dust, and temperature variation.

The main challenges in automating this application centered around controlling fluid volume and placement around densely packed components of varied heights and a component with moving parts inside tiny coating areas.

Case Study:

The Forte^® Series with IntelliJet^® Jetting System successfully automated this complex application, increasing throughput and quality outcomes while reducing set up time.
