Caboer’s 4-Layer Rigid-Flex PCB for Medical Devices is a core circuit component tailored for high-end medical products such as portable diagnostic instruments, minimally invasive therapeutic devices, vital sign monitors, and precision medical sensor modules. Featuring an integrated design of "flexible adaptation + rigid stability", it perfectly meets the core demands of medical equipment—miniaturization, high integration, and high reliability. Adopting a 4-layer multilayer rigid-flex structure, the flexible section is only 0.15mm thick, offering extreme thinness and excellent bending performance. It can flexibly navigate narrow spaces, curved structures, and connections between moving parts inside medical devices, adapting to the slender cavities of minimally invasive instruments and compact layouts of portable equipment while avoiding wiring interference. The rigid section is 0.8mm thick, balancing structural stability and lightweight requirements, reliably supporting precision chips, connectors, sensors, and other components to ensure installation accuracy and mechanical strength. It achieves an efficient integrated solution of "flexible sections for dynamic adaptation and rigid sections for fixed assembly".

In terms of technical parameters and performance guarantees, the product offers four key advantages: ① Medical-Grade Surface Protection: The full-board immersion gold process creates a uniform and dense gold layer, providing superior oxidation resistance, disinfection corrosion resistance, and low contact resistance. It can withstand repeated wiping with common medical disinfectants (e.g., alcohol, glutaraldehyde, hydrogen peroxide), avoiding signal distortion caused by oxidation or corrosion, ensuring the accuracy of physiological data transmission, and meeting the reliability requirements of medical equipment for long-term high-frequency use; ② Practical Process Design: Equipped with solder mask with white characters, the clear and distinguishable markings facilitate assembly, commissioning, sterile processing, and later maintenance of medical equipment, improving production and clinical efficiency. The through-hole board design enhances the mechanical strength and heat dissipation performance of component soldering, adapting to the stable fixation needs of precision components in medical equipment and reducing the risk of detachment caused by vibration or movement; ③ 4-Layer High-Density Integration: The 4-layer wiring structure enables scientific partitioning of power supply, signals, and grounding, effectively reducing electromagnetic interference and signal crosstalk. It supports multi-module collaboration of medical equipment (such as physiological signal collection, data processing, and wireless transmission), meeting the strict requirements of precision diagnostic and therapeutic equipment for signal integrity; ④ Medical-Grade Compliance and Durability: Using medical-grade eco-friendly substrates free of harmful substances, it complies with ISO 10993 biocompatibility standards, suitable for medical scenarios involving indirect contact with the human body. The substrate features good temperature resistance (-40℃ to 85℃) and anti-aging properties, adapting to multi-scenario use such as hospital wards, operating rooms, and emergency sites, fully complying with the strict reliability standards of medical electronic equipment.
