When dispensing nano quantities of material, exact repeatability and maximum reliability are of paramount importance. Additionally, the preparation of the material to be dispensed must meet precisely defined parameters each and every time. The Scheugenpflug provided jet dispenser can release many shots of material a second, requiring the components to be mixed and metered to perfection continuously. The LeanCNCell has a process reliability in the ±0.02 mm range and an axis speed of 160mm/sec, which satisfied most of the prerequisites of the conditions necessary to design material and application tests.
The LeanCNCell dispensing system is installed in the Georgia Tech Institute for Electronics and Nanotechnology's shared-user facility that is used by more than 700 researchers annually. The tool is housed in the 3D Systems Packaging Research Center assembly laboratory, led by Professor Rao Tummala. Besides applications in (micro) electronics packaging, the university is also looking at unique applications, such as the biomedical device arena or in dispensing novel nanomaterials. Multiple faculty are doing research in each of these areas. Other ideas include assessing thermal substances, using conductive inks in a process similar to screen printing and dispensing solder paste on custom PCB's. These materials are used for biomedical, electronic and photovoltaic purposes.
Scheugenfplug USA and Georgia Tech will monitor developments in the research results over the next few months. We expect processes to evolve that will lead to the enhancement of work flows and efficiency using the LeanCNCell. Both Georgia Tech's Institute for Electronics and Nanotechnology and Scheugenpflug are looking forward to exciting results in new dispensing methods, materials used and uncommon applications.
