Software enhances fluid dispensing precision

High accuracy fluid dispensing is combined with increased throughput and productivity in a narrow footprint, says Nordson Asymtek, at the launch of its Forte fluid dispensing system. The Forte series is designed for flex circuit and printed circuit board assembly, electro-mechanical assembly, MEMS, underfill, precise coating, and encapsulation.

Nordson Asymtek has included the Canvas software for the Forte. This delivers a new interface that simplifies programming and provides insight and control over the dispensing process, says the company.

The Forte has a stable chassis and new electrical and mechanical architectures to deliver 20 to 50 per cent higher productivity through swift acceleration and improved motion control, says Nordson. A dual-valve-ready design allows two high-frequency IntelliJet jetting systems to run simultaneously to boost throughput and quality outcomes. This halves dispense time, claims Nordson. Operating at 1.5G acceleration, the dual IntelliJet jets dispense highly accurate fluid volumes quickly, while the patented real-time skew correction automatically adjusts for workpiece rotational skew. The stability in the chassis accommodates fast motion in the x, y, and z axes without sacrificing placement accuracy.

Graphical programming in Canvas allows the operator to scan a workpiece, develop a program, on or offline, and simulate the dispensing results on a virtual canvas. Guided wizards provide step-by-step set up instructions. Quick-reference graphing and data tiles allow control of how system sensor and process data are displayed.

The integrated dual-valve service station, patented closed-loop process controls, and nozzle cleaning rail are designed to reduce operator maintenance and intervention. The space-saving system has a 600mm conveyor rail end-to-end and measure 600 x 1,374mm (23.6 x 54.1-inch) for a compact footpint.

Nordson Asymtek will display the Forte system at Nepcon Asia later this month at the Shenzhen Exhibition & Convention Center, Shenzhen, China (28 to 30 August), booth 1H20.
