Portable Diagnosis, Invisible Risk: Why HDI & Rigid-Flex PCBs Underpin Reliable Smart-Medical Electronics

For portable and wearable medical devices operating in thermally harsh, high-reliability environments, HDI (High-Density Interconnect) and Rigid-Flex architectures are the only PCB/PCBA routes that consistently maintain signal integrity, power density, and mechanical reliability—standard FR-4 multilayers are a common root cause of field failures.
