Madhu Stemmermann and SunRay Scientific: Advancing Flexible, Affordable Electronics Innovation
With a foundation rooted in chemical engineering and deep technology research, Madhu Stemmermann has emerged as a driving force behind the evolution of flexible, affordable electronics. As CEO and Co-Founder of SunRay Scientific, she has translated decades of scientific expertise into a scalable business focused on printed electronics, advanced conductive materials, and next-generation electronic interconnect solutions.
Madhu Stemmermann’s entrepreneurial journey began more than two decades ago at AT&T Bell Labs, where early exposure to breakthrough research shaped her ability to bridge science and commercialization. That experience continues to inform SunRay Scientific’s mission: to deliver innovative material and process solutions that solve complex electrical interconnect challenges across emerging electronic technologies.
Building a Global Printed Electronics Company from New Jersey
Founded in 2012, SunRay Scientific Inc. is a global materials manufacturing company headquartered in New Jersey, specializing in novel conductive adhesive technologies for printed electronics and semiconductor packaging. Led by Madhu Stemmermann (CEO) and Andrew Stemmermann (CTO), the company supports a wide range of industries, including automotive electronics, healthcare devices, smart labels, sensors, diagnostic wearables, and flexible hybrid electronics.
SunRay Scientific operates from a state-of-the-art prototyping and manufacturing facility in Eatontown, New Jersey, strategically designed to support materials manufacturing, alpha and beta validation, customer qualification, and scalable production. The facility reflects the company’s focus on speed-to-market and manufacturability—critical factors for companies developing advanced electronic systems.
Enabling Printed Electronics with Materials and Manufacturing Processes
What differentiates SunRay Scientific in the printed electronics ecosystem is its ability to deliver both advanced materials and the end-to-end processes that enable real-world adoption. Unlike suppliers that focus solely on materials, SunRay provides integrated solutions that simplify manufacturing while improving performance and reliability.
The company’s facility includes automated SMT lines, die placement systems, printed electronics lines, and high-volume conductive material manufacturing capabilities. With equipment such as ASM C-Place, deck printers, Heller ovens, and Class 8 cleanroom environments, SunRay’s technology is engineered to perform consistently in high-volume production environments.
Z-TACH® ACE and Productivity-Driven Electronics Manufacturing
At the core of SunRay Scientific’s technology portfolio is Z-TACH® ACE, a magnetically alignable conductive adhesive designed to replace traditional solder-based interconnect methods. Built on a polymer matrix with highly conductive ferromagnetic particles, Z-TACH® ACE enables Z-axis electrical connections when activated using SunRay’s proprietary ZMAG magnetic pallet.
This innovation eliminates multiple manufacturing steps—such as solder bumping, patterning, and secondary underfilling—while delivering strong adhesion, fine-pitch capability, and mechanical reliability. By acting as its own underfill, the technology reduces process complexity, lowers cost, and significantly improves productivity for printed electronics and semiconductor packaging applications.
Driving the Future of Flexible and Wearable Electronics
Under Madhu Stemmermann’s leadership, SunRay Scientific continues to push the boundaries of what’s possible in flexible electronics, wearable sensors, diagnostic patches, and automotive interior electronics, including applications tied to autonomous driving and smart devices. By combining material science, manufacturing expertise, and scalable processes, the company plays a key role in making advanced electronics more accessible, reliable, and affordable.
From its New Jersey roots to its global customer base, SunRay Scientific exemplifies how deep technical innovation paired with entrepreneurial vision can reshape the future of printed and flexible electronics.
