Type: Flexible Printed Circuit (FPC) for medical device controllers, designed specifically for medical controller systems, with excellent signal transmission stability and environmental adaptability. Whether it is the parameter acquisition circuit of a portable monitor, the precise control module of an infusion pump, or the transmission link of operating instructions for a surgical robot, it can flexibly adapt to the complex spatial layout inside medical equipment (such as the dense modules of miniaturized equipment and the dynamic connection of movable parts) to achieve distortion-free transmission of biosignals, control instructions, and display data, and provide circuitry support for the precise operation of medical equipment.

Minimum line width/spacing: High precision of 0.07mm/0.06mm. This parameter is optimized for the characteristics of weak signals in medical equipment: 0.07mm line width ensures lower transmission loss of bioelectric signals (e.g., μV signals of ECG and blood oxygen sensors) (signal attenuation rate ≤0.2dB/m) and reduces the distortion of weak signals in transmission; 0.06mm line spacing realizes dense wiring in limited wiring space to support the transmission of multi-channel signals (e.g., heart rate, blood pressure, and blood oxygen signals of monitor) in parallel. It supports parallel transmission of multi-channel signals (e.g. synchronized transmission of heart rate, blood pressure and blood oxygen signals of monitors), avoids detection errors caused by signal crosstalk (crosstalk rejection ratio ≥70dB), and guarantees the accuracy of data acquisition.

Layers: 2-layer structural design, signal management through scientific layering:

Signal layer: Differential routing and equal-length wiring design to optimize the transmission path of biological signals and control commands to meet the high bandwidth requirements of medical equipment (supporting signal transmission at sampling rates above 1MHz);

Ground layer: Large-area copper foil cover forms an electromagnetic shielding barrier, effectively isolating the electromagnetic interference of the device's internal power supply modules and motors to ensure that the weak biological signals are transmitted synchronously, ensuring that the data acquisition accuracy is protected. Ground layer: a large area of copper foil covers to form an electromagnetic shielding barrier, effectively isolating the electromagnetic interference of power modules and motors inside the device, ensuring the purity of transmission of weak biological signals (e.g., EEG signals, EMG signals), and reducing the detection noise (signal-to-noise ratio ≥ 80dB).

The two-layer synergy significantly reduces the risk of signal interference, especially suitable for critical care equipment scenarios that require high detection accuracy.

Thickness: 0.2mm thin and light, perfectly suited to the miniaturization and portability of medical equipment. In the trend of portable medical equipment (such as handheld ultrasound, wearable monitoring equipment), can significantly reduce the space occupied by the wiring, for a larger capacity of the battery, higher precision transducers to release the installation space; at the same time to enhance the flexibility of bending (support for the smallest bending radius R = 1mm), to adapt to the dynamic wiring of movable parts (such as joints of the joints of the surgical instruments), to avoid fatigue breakage of the wiring.

Surface treatment: the use of immersion gold 2 micro-inch process (nickel layer thickness ≥ 5μm, gold layer thickness ≥ 0.05μm), bringing multiple medical-grade advantages:

gold layer of conductivity and stability, contact resistance ≤ 8mΩ, reducing the transmission loss of weak biological signals, to ensure that the monitor, analyzer, the detection error ≤ 0.5%;

2 micro-inch thickened layer of excellent corrosion resistance, can withstand the alcohol, iodine vapors, hydrogen peroxide and other common medical disinfectants frequently wiped. The 2-micron thick gold layer has excellent corrosion resistance and can withstand frequent wiping with common medical disinfectants such as alcohol, povidone-iodine, hydrogen peroxide and other disinfectants (no corrosion after 1,000 disinfectant wipe tests), adapting to the stringent disinfection requirements of medical environments.

The gold layer has excellent biocompatibility (in compliance with ISO 10993 biocompatibility standards), with no risk of heavy metal precipitation, ensuring the safety of equipment components in contact with the human body (e.g., wearable controller).
