Protection method for medical equipment PCB production

During the use of the circuit board, a large current will be generated in a short time. If a large current is generated for a long time, it will certainly make the main board and circuit of the equipment generate a lot of heat. Then the protective layer must be used for protection. Based on all kinds of PCB materials, the best material for PCB circuit protective layer is three proofing adhesive. This paper introduces the advantages and construction technology of three proofing adhesive in medICal circuit board protection.

1. Introduction to main performance advantages of three proofing adhesive

First, the strength is high. The three proofing adhesive has high strength. After curing, the three proofing adhesive has good compression and shear resistance, and can protect the circuit board in friction.

Second, it has good durability. In the medical industry, the requirements for the continuous work of the main circuit board and the circuit are relatively high. The three proofing adhesive has a very good durability. Although the thickness is relatively thin, it can last for deCADes without damage under the high intensity of the line movement.

Third, there is no pollution. At present, the technology is the core of the production process of the three proofing adhesive, so the PCB technology of the three proofing adhesive is gradually becoming mature, and the three proofing adhesive is now non-toxic and harmless, clean, environmental friendly and conducive to human health. Therefore, the three proofing adhesive can be widely used in the medical mainboard and circuit.

The fourth is to adapt to the environment. The three proofing glue has the functions of mildew prevention, corrosion prevention and radiation prevention, so it can be used in a variety of environments, such as rooms with radiation. Adapting to a variety of environments, the three proofing adhesive has also been widely used in the medical industry. However, it is necessary to choose high-quality manufacturers. We can focus on adhesive research and provide integrated adhesive application solutions. The functions of three proofing glue and radiation protection are very strong, which can be used in CT room and other rooms with strong radiation intensity.

2 Introduction to construction technology

Although three proofing adhesives have many advantages, they still put forward high requirements for PCB construction. First, ensure the cleanness of the construction environment. During the construction of the line, ensure the cleanness of the line. In case of mildew, corrosion and dust on the circuit board, clean it immediately to maintain a clean and hygienic construction environment. Second, control the thickness of the three proofing adhesive. The three proofing adhesive has good strength and durability. Therefore, it is very important to control the thickness of the three proofing adhesive in order to reduce the weight of the line, Generally, it is about 40-60mm, which is enough to complete the line protection mission, and the three proofing glue construction should be uniform. Thirdly, it is necessary to do a good job in curing. During the curing process of the three proofing adhesive, it is very important to do a good job in its protection. It is required to control the humidity, temperature and wind force of the line well to maintain the good curing of the pcb line.
