Advanced Patterning with EHD and Inkjet

One of the founding ideas of Notion Systems was to replace the current subtractive process chains with additive process steps in electronics manufacturing. The n.jet inkjet platform is used to produce electronic displays, printed circuit boards, semiconductor components, as well as high precision optical 3D parts, covering the full range of solutions from lab to fab. Main inkjet applications are coating, dispensing or patterning. Patterning can easily be done with inkjet printing, as it is a digital printing process with drop-on-demand functionalities. Depending on the print head and the material used, resolutions of 20 µm are possible. Despite the fact that this is an interesting technology for any industries, there are limitations with this technology for certain display or semiconductor applications. For this reason, Notion Systems has invested in a collaboration with Scrona AG of Switzerland, which has developed an EHD printing technology.Electrohydrodynamic (EHD) printing is a new high-resolution printing technology that enables maskless, direct-write, non-contact, conformal and additive patterning at the micron scale with a variety of ink systems and materials. Print resolution exceeds that of conventional inkjet printing by two to three orders of magnitude, it paves the way for additive printing in applications dominated by photolithographic microfabrication and enables entirely new devices made from micro-scale building blocks.MEMS multi-nozzle printheads with ultra-high print resolution, enabling applications with resolution greater than 1 μm. This Research and development tool is targeted to advanced development labs in various fields of micro-fabrication and digital additive manufacturing.
