The difference between medical PCB and ordinary PCB

The difference between medical PCB and ordinary PCB

The development of society is faster and faster, and people are paying more and more attention to health, which leads to higher requirements for the performance of PCB materials in the medical industry. What are the technical requirements for reliability, high frequency, high speed, and high conductivity of pcb in medical treatment?

The medical PCB board has become one of the most complex and challenging in the industry. Many people have said that medical PCBs and ordinary PCBs are the same board. What are the differences between them?

1) "Safety" and "Reliability": These are the core issues of PCB boards in the medical industry. Life support products or high-end products refer to IPC-3 level standards, and non-life support or low-end products refer to IPC-2. The large-scale medical terminal establishes its independent enterprise standard, strictly controls the reliability of the product. So this point is very important.

2) Long service life: General product warranty time is more than 5 years, large medical equipment requires at least 10 years, and the product lasts for a long time.

3) Large hierarchical span: from consumer medical products that meet conventional requirements, to mid- and high-end medical products that meet high reliability and high stability requirements, to small portable products that meet high-density, high-integration, and smart Versatile and multifunctional wearable medical products.

4) Product conservative: The application of new medical technologies and new products to the market is slow, and the verification and testing of new products are repeated, which often requires comprehensive evaluation.

5) Traceability: Products require strict process records and product traceability. Some large medical terminals require the traceability of 10-year processing records.

6) The process and fire rating requirements of medical PCB boards are different; ordinary PCB processes have different methods for tin spraying and cleaning boards. On the premise of taking process measures and ensuring quality and safety, it can be used for repairs as appropriate.

7) The general medical PCB demand is small and the process requirements are high： such as HDI, back drilling, multiple pressing, mixed pressure, high precision, special impedance, thick copper, thick gold, embedded copper blocks, etc. The price is generally very high, which is also different from ordinary pcb boards.

Among all medical PCB boards, FR-4 is the most widely used. For the design of medical pcb, the choice of FR-4 board will be different according to the positioning of its own products and the control of the price of raw materials. For large-scale hospital institutions, reliable pcb boards should be selected.
