A new specialized deposition facility helps in RICE laboratories
The Nordson EFD ProPlus 4 robotic three-axis dispenser, equipped with laser surface sensing, used by researchers at the Regional Innovation Center of Electrical Engineering, Faculty of Electrical Engineering, can precise deposition of motifs, lines, and dots on various types of surfaces and components.
Thanks to accurate laser scanning, the deposition tip of the device accurately copies surface irregularities, including protrusions and depressions. The dispenser will primarily serve the research of new assembly technologies and surface contacting of power semiconductor components on hybrid modules with built-in intelligence. Such modules find particular application in concentrated photovoltaic systems, power converters for transport systems and lighting modules for the automotive industry.
Due to the high versatility, the dispenser will also be used for research into fully additive production of electronic systems with unconventional functional properties, such as highly flexible and elastic electronic systems on plastic films, paper or textiles.
The employees of the Faculty of Electrical Engineering will take advantage of the high modularity of the whole equipment as they allow installation and easy replacement of a wide range of deposition tools. For example, for carbon nanoparticle and sensor structures based on carbon nanotubes, its spray valve is particularly useful for uniformly applying material dispersions to the sensors.
The installation of the new RICE equipment complements existing screen printing and aerosol jet technologies, creating a comprehensive technology portfolio for the additive implementation of electronic structures ranging from highly miniature conductive connections with sizes as small as 10 μm to large planar structures covering up to tens of cm.
