Defense Speak Interpreted: The Impact of Venture Capital-backed Defense Contractor Firms
Flexible Circuit Technologies Inc. (FCT), a Minnesota-based flexible circuit and advanced electronics manufacturer, is pleased to announce the development of its Liquid Leak Detection Flex Assembly, a custom-engineered sensing solution designed for liquid-cooled AI servers, high-performance computing (HPC) systems, cold plates, manifolds, quick disconnects, coolant distribution units (CDUs), and other mission-critical electronics.
As AI and HPC platforms continue to move toward direct-to-chip liquid cooling, early detection of coolant leaks is becoming increasingly important. FCT's flexible sensing assembly is designed to fit around the geometry of the cooling system, enabling leak detection close to potential failure points while maintaining a thin, lightweight profile in space-constrained server and rack environments.
The Liquid Leak Detection Flex Assembly can be customized for the application, including sensing patterns, circuit geometry, connector interfaces, and multiple detection zones. Potential monitoring locations include supply and return quick disconnects, GPU and CPU cold plates, manifolds, coolant lines, CDUs, and server trays. The flex-based architecture is intended to help OEMs and cooling-system manufacturers integrate leak sensing directly into their equipment rather than relying solely on facility-level leak detection.
"The rapid growth of liquid-cooled AI infrastructure is creating a new need for thin, compact, highly customized leak-detection solutions," said Ray Cottrell, EVP of Flexible Circuit Technologies. "FCT's strength is designing flexible circuits around the customer's mechanical and electrical requirements. This concept allows us to bring that capability directly to cold plates, manifolds, quick disconnects, and server-level cooling assemblies where early detection can help protect high-value electronics."
FCT plans to work with server OEMs and ODMs, liquid-cooling companies, cold-plate manufacturers, thermal-management suppliers, and data-center infrastructure providers to tailor the assembly to specific cooling architectures. FCT's engineering team can support concept development, rapid prototyping, design-for-manufacturing, flex circuit fabrication, assembly, and scalable production.
