During the use of the circuit board of medical equipment, a large current will be generated in a short time. If a large current is generated for a long time, a large amount of heat will be generated in the main line board and circuit of the equipment. Then it must be protected by a protective layer. Synthesizing all kinds of materials, the best material for line protective layer is three-proof glue. This paper introduces the advantages and construction technology of three-proof adhesive in medical circuit board protection.
1 Introduction of main performance advantages of three-proof adhesive
First, the strength is high. Three-proof glue has high strength. After curing, the three-proof glue has good compression and shear resistance, and can protect the circuit board in friction.
Second, the durability is good. In the medical industry, the requirements for the continuous work of the main circuit board and lines are relatively high, and the durability of the three-proof adhesive is very good. Although the thickness is relatively thin, it can last for decades without damage under the high-intensity movement of the lines.
Third, there is no pollution. At present, the manufacturing technology of three-proof glue is based on science and technology, so the technology of three-proof glue is gradually maturing. At present, three-proof glue is non-toxic, harmless, clean, environmentally friendly and conducive to human health. Therefore, the three-proof adhesive can be widely used in medical mainline boards and lines.
Fourth, adapt to the environment. Three-proof glue has the functions of preventing mildew, corrosion and radiation, so it can be used in various environments, such as rooms with radiation. Adapting to various environments, three-proof glue is widely used in medical industry. However, it should be noted that it is necessary to choose high-quality manufacturers. Can focus on adhesive research and provide integrated adhesive application solutions. The functions of glue protection and radiation protection are very strong, and it can be used in CT rooms and other rooms with strong radiation intensity.
2 Introduction of construction technology
Although the three-proof adhesive has many advantages, it still puts forward high requirements for circuit board construction. First of all, ensure the cleanliness of the construction environment. During the line construction, it is necessary to ensure the cleanliness of the line. If mold, corrosion and dust are found on the circuit board, it should be cleaned up immediately to maintain a clean and hygienic construction environment. Secondly, control the thickness of the three-proof adhesive, which has good strength and strong durability. Therefore, in order to reduce the weight of the line, it is very important to control the construction thickness of the three-proof adhesive, generally about 40-60mm, which is enough to complete the mission of line protection. To do a good job of maintenance again, it is very important to do a good job of protection in the curing process of the three-proof adhesive. It is required to control the humidity, temperature and wind force of the line well to maintain the good curing of the line.
