1. Medical PCB fabrication Requirements

● Medical Standards  

Medical printed circuit board design involves strict requirements. It must comply with regulations and standards such as ISO 13485, IEC 60601, and RoHS directives to ensure that medical device quality management system standards are safe and reliable.

● Durability

Medical equipment usually needs to run long and requires extremely high reliability. To avoid failures, the long life requirement should be considered during PCB design and manufacturing.

● Safety

The circuit board design and manufacturing of medical equipment require extremely high safety to ensure the safety of patients and operators while ensuring the reliable operation of the equipment. In PCB fabrication, optocouplers and transformers achieve electrical isolation, especially between high-voltage and low-voltage circuits to prevent electric shock. Leakage current protection measures should be considered in the design to prevent dangers caused by leakage and ensure the safety of patients and operators.

● Component Selection

Choose high-reliability components that have been medically certified to reduce the failure rate, consider flame-retardant components in the design of medical circuit boards, and use flame-retardant materials that meet the UL 94 V-0 standard to prevent fire risks.

● Signal Integrity

Medical equipment must operate stably in various complex electromagnetic environments, and medical PCB board design must have good electromagnetic compatibility. Signal integrity should be considered in the design to prevent signal distortion, especially for sensitive analog and high-speed digital signals.

● Testing

Since medical equipment is directly related to patients' life safety and health, medical PCB boards must pass rigorous tests and certifications to ensure their safety and effectiveness. Each PCB must undergo comprehensive functional testing before leaving the factory to ensure all circuits work properly. Test under different environmental conditions such as temperature, humidity, and vibration to verify PCB reliability.
