4 Major Medical PCB Design Challenges (And Solutions)

1. Signal Integrity Issues

Medical devices require noise-free signal transmission for accurate readings. Poor PCB layout can distort data.

✅ Solution: Use proper grounding, shielding, and impedance control.

2. Electromagnetic Interference (EMI)

Nearby electronics can disrupt sensitive medical equipment.

✅ Solution: Follow IEC 60601-1-2 for EMI/EMC compliance.

3. Power Efficiency Needs

Many portable devices (e.g., glucose monitors) rely on battery power.

✅ Solution: Optimize circuits for ultra-low power consumption.

4. Strict Regulatory Compliance

Faulty PCBs can endanger lives.

✅ Solution: Manufacturers must meet ISO 13485, FDA, and IPC Class 3 standards.
