128 nozzle print head for semiconductor equipment
Scrona in Switzerland has shown its third generation print head with 128 nozzles for semiconductor advanced packaging, display manufacturing and consumer electronics.
The electrohydrodynamic (EHD) print head was shown at the CES 2025 show in Las Vegas for the first time and marks a major milestone for EHD printing in mass-production in a newly developed print engine for integration into production tools by the end of Q1 2025. The print heads are built in Scrona’s clean room facility in Zurich with a new production line being built in Taiwan.
SCRONA’s GEN3-128 printhead offering 128 fully digital nozzles in a staggered 2-line-configuration with an effective nozzle pitch of 100µm.
“The rapid development from 8 to 48 and now to 128 nozzles in such a short time is a testament to the scalability of our MEMS-based EHD Gen-3 platform and execution of our team,” said Dr. Patrick Galliker, CTO and Co-Founder of Scrona.

In semiconductor manufacturing the print head can be used for die-attach applications, dispensing ultra-small adhesive volumes with unparalleled accuracy. With conducting inks, it also allows high-resolution printing of conductive interconnects for advanced AI chiplets and chip manufacturing innovations.
The system can also be used for applying quantum dots and colour filters for next-generation micro-LED and OLED displays as well as high-accuracy printing of adhesives and sealants for display packaging, facilitating thinner and flexible substrates.
“We are thrilled to unveil our 128-nozzle EHD printhead at CES 2025,” said Dr. Patrick Heissler, CEO of Scrona. “This breakthrough paves the way for manufacturers to achieve greater performance, miniaturization, and efficiency in production processes while unlocking new opportunities for innovation in advanced technologies.”
Scrona is a spin-off from ETH Zurich and developed the industry’s first multi-nozzle printing platform that can digitally print with sub-micron precision, on any material and at scale. Its patented electrostatic printing technology enables new designs not feasible for current printing processes while significantly reducing material, energy and water consumption.
