MILTON, N.Y., March 17, 2026 (GLOBE NEWSWIRE) -- Sono-Tek Corporation ( SOTK ) , a global provider of precision ultrasonic coating systems, today announced a technical collaboration with Diamond Quanta (DQ), a developer of engineered diamond-on-glass and engineered-diamond materials for optics, thermal, semiconductor, and quantum systems.

Under the collaboration, Sono-Tek’s precision ultrasonic coating technology is expected to be integrated into Diamond Quanta’s manufacturing workflow to support repeatable thin-film deposition and multilayer integration across engineered diamond applications.

The collaboration is focused on strengthening process repeatability, film uniformity, and manufacturability as Diamond Quanta advances its materials platform toward OEM qualification and scalable manufacturing environments.

Supporting Standardized Process Architecture

Diamond Quanta has described its approach as a standardized process architecture designed to integrate engineered diamond interfaces into repeatable, qualification-ready manufacturing workflows compatible with existing semiconductor and electronics toolchains.

Through this collaboration, Sono-Tek ( SOTK ) systems are expected to support:

Repeatable thin-film deposition within multilayer diamond stacksImproved coating uniformity and process consistencyStructured progression toward OEM qualification environmentsAlignment with established semiconductor and electronics manufacturing ecosystems

“Sono-Tek’s precision ultrasonic coating systems are designed to enable consistent, high-uniformity thin-film integration across advanced device architectures,” said Steve Harshbarger, Chief Executive Officer of Sono-Tek ( SOTK ). “We are pleased to collaborate with Diamond Quanta as they advance their engineered diamond technologies toward scalable manufacturing.”

“Establishing a repeatable manufacturing architecture requires not only breakthrough materials but standardized process modules that OEMs can adopt with confidence,” said Adam Khan, Founder and CEO of Diamond Quanta. “Our collaboration with Sono-Tek ( SOTK ) strengthens the integration layer of our engineered diamond-on-glass platform and supports disciplined progression toward scalable qualification.”
