In the medical equipment, PCB(printed circuit board), as the core barrier of the electronic system, directly influences the reliability, precision, and security of the equipment. With the development of medical technology, PCB has wider and wider applications in high-precision and top-notch medical equipment.

1. Typical Medical Equipment Applications

• Imaging diagnostic equipment
• CT/MRI scanner: using high multilayer PCB(over 12L) to propagate the high-speed signal and ensure there is no image noise
• Ultrasound equipment: high-frequency PCB(like Rogers material) can realize precise acoustic signal transmission

• Vital Signs Monitoring Equipment Applications
• ECG and oximeter: flexible PCB(FPC) fits the body well, with lightweight, and supports portable design
• Ventilator: high-reliability PCBs can ensure the system runs stably long time

• Treatment and surgical equipment Applications
• Pacemakers and defibrillators: Using ultra-small HDI PCB, such implantable devices need to meet biocompatible packaging
• Laser scalpel: High-temperature-resistant PCB can work well and withstand large current pulses

2. Core Requirements for Medical Grade PCB

• Signal Integrity: impedance control (±5% range) to avoid distortion of monitoring data (such as ECG signals)
• Safety and Compliance: complies with IEC 60601-1 (medical electrical safety standard) and RoHS lead-free requirements
• Miniaturization design: Use HDI PCB design to meet the needs of wearable/implantable devices

3. Technology Trends

• Flexible and rigid-flexible PCBs can be used in some bendable medical equipment, like endoscopes
• Anti-interference designs are necessary to prevent electromagnetic interference(EMI) in the medical environment
• Antimicrobial coating should be used to inhibit bacterial growth, for example medical equipment in the ICU
