Why do components need to be sealed?

Component gluing is a common process in the manufacturing and assembly of electronic components, which mainly aims to package, fix, and protect electronic components by using specific gluing materials. This process plays an important role in improving the performance of components, extending their service life, and enhancing their resistance to environmental impacts.

Component gluing is a common process in the manufacturing and assembly of electronic components, which mainly aims to package, fix, and protect electronic components by using specific gluing materials. This process plays an important role in improving the performance of components, extending their service life, and enhancing their resistance to environmental impacts.

1. Protect components from external environmental influences:
Component gluing can form a protective film that covers the surface of electronic components, preventing external moisture, dust, chemical substances, etc. from corroding the components. This is particularly important for electronic devices used in humid and corrosive environments, as it helps prevent component failure due to environmental factors.

2. Improve the mechanical strength and vibration resistance of components:
After gluing, a strong protective layer is formed on the surface of the components, making them more resistant to vibration and mechanical impact. This has important practical significance for equipment that needs to operate under harsh working conditions, such as automotive electronic systems, aerospace equipment, etc.

3. Improve the insulation performance of components:
Adhesive materials usually have good insulation performance, which can effectively isolate electrical signals between electronic components, reduce signal crosstalk, and improve circuit stability and reliability.

4. Improve heat dissipation performance:
Some adhesive materials have good thermal conductivity, which can help components more effectively dissipate the heat generated. This can help improve the efficiency and stability of some high-power-density components, such as power amplifiers, processors, etc.

5. Increase the fire resistance performance of components:
Some special adhesive materials have flame-retardant properties, which can improve the fire resistance of electronic components to a certain extent and reduce the risk of fire in electronic devices.

6. Improve chemical corrosion resistance:
In some special working environments, components may be corroded by chemicals. The selection of adhesive materials can be based on specific needs to make the components more resistant to chemical corrosion.

7. Reduce mechanical stress on components:
Adhesive materials have a certain degree of elasticity, which can reduce the impact of external mechanical stress on components, improve the mechanical stress resistance performance of components, and extend their service life.

8. Enhance sealing performance:
The glue-filling process can fill the small pores on the surface of components, improve the sealing performance of components, prevent the penetration of liquids and gases, and thus enhance the stability of components.

9. Reduce noise and vibration:
For some applications that are sensitive to noise and vibration, such as audio equipment, precision instruments, etc., gluing can reduce small vibrations and resonances between components, and improve equipment performance and working accuracy.
