Medical device PCBs have stricter requirements than consumer electronics. A failure in a pacemaker or patient monitor is not an inconvenience — it can be life-threatening. That changes everything about how the boards are designed, manufactured, and tested.
Regulatory requirements
- ISO 13485 quality management system
- FDA 21 CFR Part 820 compliance for US market
- IEC 60601 safety and essential performance
- Full material and process traceability
- Lot traceability from raw laminate to finished board
Manufacturing considerations
- Cleanroom or controlled environment production
- IPC Class 3 acceptance criteria minimum
- Extended electrical testing (100% netlist comparison)
- HALT/HASS testing for critical applications
- Material certification and documentation packages
Design for medical reliability
Medical PCBs often use thicker copper, additional conformal coating, and redundant design elements. Component selection must account for long product lifecycles — medical devices remain in service for 10-15 years, so component availability matters.
Documentation requirements
Every medical PCB requires a complete Device History Record. This includes incoming material certificates, process parameter logs, inspection records at each stage, final test data, and material lot traceability. Your PCB manufacturer must be able to provide all of this.
Choosing a medical PCB manufacturer
- Verify ISO 13485 certification — not just ISO 9001
- Ask about lot traceability capabilities
- Confirm cleanroom or controlled environment
- Request sample documentation packages
- Audit their quality system if possible
