About SunRay Scientific

SunRay Scientific was founded in 2012 to commercialize and further develop innovative electronic materials and interconnect technologies pioneered by Dr. Kumar Khanna. Dr. Khanna had a distinguished research career that included AT&T Bell Laboratories. After Dr. Khanna's retirement, his daughter, CEO Madhu Stemmermann, and son-in-law, CTO Andrew Stemmermann, co-founded the company to commercialize and further develop this technology. Madhu Stemmermann brings over 25 years of senior leadership experience from major corporations like General Electric and Honeywell, while Andrew Stemmermann contributes over 25 years of expertise in conductive adhesive formulation and application development. SunRay Scientific transitioned to a C-corporation in 2021.

SunRay Scientific develops and manufactures lead-free, custom-engineered interconnect solutions for the healthcare, consumer electronics, automotive, and defense industries. Its business model focuses on providing these materials to integrated electronic device manufacturers, component suppliers, and OEMs. A significant portion of its business involves federal contracts and grants, particularly with the Department of the Air Force. The company's core offering is its patented ZTACH® Anisotropic Conductive Epoxy (ACE) system, which allows for cost-effective miniaturization and improved throughput by integrating with existing manufacturing infrastructure. This system works by using a magnetic pallet to create self-assembling, z-axis electrical and thermal interconnections when cured at low temperatures, a process that doesn't require pressure. Beyond the ZTACH® system, SunRay produces a range of customized conductive inks, epoxies, and encapsulants designed to address challenges like silver migration and to enhance durability in printed and flexible hybrid electronics. These materials are crucial for applications such as flexible wearables, semiconductor packaging, and X-ray imaging devices.

The firm has demonstrated consistent growth and has successfully secured funding to support its expansion. SunRay Scientific has raised a total of $3.42M, with a notable funding round in 2022 that surpassed its $1.5 million goal to close at over $2.5 million. This capital influx was earmarked for hiring new personnel, acquiring key production equipment, and expanding its patent portfolio. Investors include Tech Council Ventures, JumpStart New Jersey Angel Network, Golden Seeds Ventures, and Accelerating Angels. The company has gained recognition for its products, including winning a National Innovation Challenge for its ZTACH® ACE epoxy.
