What SunRay Scientific Inc. does

SunRay Scientific Inc. (legally SunRay Scientific LLC, re-launched as a C-corp in 2021) is a New Jersey-based materials technology company that develops and commercializes proprietary conductive adhesives, inks, encapsulants, and epoxies for advanced electronic packaging. Its flagship technology is ZTACH ACE, a Z-Axis pressure-less anisotropic conductive epoxy that cures at 80-160°C or under UV in a magnetic field, enabling self-assembly of conductive Z-axis columns with less than 100-micron feature sizes, 7-20 mOhm connection resistance, and greater than 10^11 Ohms X-Y insulation. The companion ZMAG Magnetic Pallet System provides the patented magnetic field hardware that drives self-assembly during cure. The company was founded to commercialize polymer thick film technology invented by Bell Fellow Dr. Kumar Khanna at AT&T Bell Labs and Lucent Technologies more than 20 years ago, and is now led by his daughter Madhu Stemmermann (CEO) and son-in-law Andrew Stemmermann (CTO).

The company serves electronics manufacturers, defense contractors, and medical device companies across five primary segments: flexible electronics and wearables, semiconductor packaging, medical devices, defense and aerospace, and LED lighting. Its go-to-market is a direct enterprise field sales motion supported by a VP of Sales and Business Development, a Director of Operations and Engineering, technical conference participation (IEEE ECTC, TechConnect), and consortium engagement (NextFlex, SEMI-FlexTech, AFFOA). Revenue is generated from two streams: hardware sales of advanced materials (ZTACH ACE, ZMAG, conductive inks, epoxies, UV encapsulants) and custom interconnect solution engineering, supplemented by non-dilutive SBIR/STTR grants from the Department of Defense and Department of Energy totaling over $10M between 2017 and 2020. Named customers include the U.S. Air Force Research Laboratory, which has publicly endorsed ZTACH ACE for ultrasonic transducer bonding onto flexible substrates.

SunRay raised $2.5 million in equity in September 2022 from a syndicate of ten angel groups, including Broad Street Angels, Golden Seeds, Jumpstart New Jersey Angel Network, Tech Council Ventures, and Westchester Angels. The company holds ISO 9001:2015 certification, holds registered trademarks for ZTACH, ZMAG, and SUNRAY, and has won multiple innovation awards including the 2022 TechConnect National Innovation Challenge and the 2019 Murata Innovation Challenge. No institutional venture capital, private equity, or parent-company ownership is evidenced in the source data.
