The breathing medical PCB board has become one of the most complex and challenging in the industry.
Many people in the industry have said that breathing medical PCB and ordinary PCB are the same board. Is there any difference?
The answer is yes.
In summary, there are 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.
Large-scale medical terminals have established their own independent and standardized corporate standards to strictly control the reliability of their products.
So this point is very important.
2) Long service life: the general product warranty time is more than 5 years, and the large medical equipment requires at least 10 years. At the same time, the product
The use lasts for a long time.
The difference between breathing medical PCB and ordinary PCB is still there.
3) Large level span: from consumer medical products that meet conventional requirements, to mid-to-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: The product requires strict process records and product traceability, and some large-scale medical terminals require assurance
Traceability of PCB processing records for 10 years.
6) The process and fire protection requirements of breathing 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 breathing medical PCB demand is small, and the process requirements are many, such as HDI, 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 breathing medical PCB boards, FR-4 is the most widely used.
For breathing 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 large-scale hospital institutions, reliable pcb boards should be selected.
