Process

With the Select Coat process, Nordson Asymtek has created and continuously developed a pioneering, patented technology for automatic, selective protective coating in a single operation. It operates quickly and precisely, without overspray, and can be efficiently and reliably integrated into existing manufacturing processes.

With the Select Coat process, Nordson Asymtek has created and continuously developed a pioneering, patented technology for automatic, selective protective coating in a single operation.It operates quickly and precisely, without overspray, and can be efficiently and reliably integrated into existing manufacturing processes.

Thousands of customers already utilize this selective coating process in electronic manufacturing, often as a complete and automated coating line.

Technology

The Select Coat – SL Series protective coating systems have been developed for the highest possible quality and productivity in automatic coating processes.

High speed and precision with consistently high quality is achieved thanks to the special valve technologies and integrated closed-loop process control.

The process parameters are recorded and can be analysed accordingly for order tracking – keyword traceability and Industry 4.0. If required, all information can be exchanged via a customised factory information system.

Operation and programme creation are uncomplicated and can be made even more convenient with the appropriate camera and offline software.

Unique process control

A set of special developed process contral features helps to secure a continius high process quality and include:

  • The Viscosity Control System (VCS)
  • The Laser Fan Width Control (LFWC)
  • The flow rate measurement

With the VCS, the material is conveyed with a circulating, heated and closed coating system to compensate for viscosity fluctuations in changing ambient conditions. The LFWC measures the width of the coating curtain using a laser and automatically adjusts if necessary. The correct amount of material is continuously checked with the flow rate measurement and readjusted in a closed loop if necessary.

EasyCoat Software

The EasyCoat Software by Nordson Asymtek includes intuitive visual programming for the coating system, as well as process control and traceability.

Key benefits include:

  • Drag-and-drop programming – simple and fast
  • Customizable settings
  • Improved accuracy through applicator tip tracking
  • Graphical offline programming
  • Process optimization through offset calibration
  • Generation of process data for SPC systems
