The development of society is fast. People are paying more and more attention to health, and the equipment in the medical industry puts forward higher requirements on the performance of pcb materials. What are the technical requirements for reliability, high frequency, high speed, and high conductivity of pcb in medical treatment?

FPC supplier tells you that the medical PCB circuit boards have become one of the most complex and challenging in the industry. Many people in the industry have said that medical PCB and ordinary PCB are the same board. Is there any difference?

To sum up, the medical PCB circuit board has the following aspects:

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 standard 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. The difference between medical PCB and ordinary PCB is still there.

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 is repeated, which often requires comprehensive evaluation.

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

6) The process and fire protection requirements of medical pcb boards are different. The ordinary pcb process has different methods for spraying tin and cleaning the board. 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, the process requirements are many, back drilling, multiple pressing, mixed pressure, high precision, special impedance, thick copper, thick gold, embedded copper block, etc. The price focus will be very low, which is also different from ordinary pcb boards.

Among all medical PCB board materials, FPC supplier suggests FR-4, as FR-4 is the most widely used. For medical PCB design, there will be differences in the choice of FR-4 board based on the positioning of its own products and the control of the price of raw materials. For circuit boards used in medical equipment, reliable medical pcb circuit board manufacturers should be selected.
