We know that semiconductor sealing rings are commonly used sealing materials in the packaging of semiconductor devices. They effectively protect semiconductor components from external damage, thereby extending the service life of the devices. Specifically, their benefits include the following points:

1. Dustproof and waterproof. It prevents dust and moisture from entering the internal components, thereby avoiding damage to the devices. In humid and dusty environments, the role of semiconductor sealing rings becomes especially significant.
2. Antioxidant properties: It can resist oxidation, protecting the internal metal components of the device from corrosion and effectively slowing down the aging process of the components.
3. Maintain the original dimensions. It possesses a certain degree of elasticity and tensile strength, effectively preventing components such as circuit boards, chips, and pins from experiencing dimensional deformation due to temperature fluctuations.
4. Excellent electrical performance. The material exhibits low dielectric constant and a small tangent of the dielectric loss angle, ensuring no adverse impact on the electrical characteristics of components.
5. Others. It can also enhance the component's resistance to impact, compressive strength, and thermal performance, safeguarding the components from mechanical damage and high-temperature melting points.
In summary, its benefits are diverse and multifaceted. In the semiconductor industry, semiconductor sealing rings not only serve as a common material for protecting components but also function as a reliable platform for testing these components. Looking ahead, as the semiconductor industry continues to evolve, semiconductor sealing rings will find increasingly widespread applications across various fields, enabling us to better safeguard our devices and ensuring greater safety and efficiency in both our daily lives and professional endeavors.
It is a critical component in the semiconductor packaging process. Proper selection and use of semiconductor sealing rings can enhance the quality and efficiency of packaged products, while improper usage may lead to failure of semiconductor devices. The following are important considerations for semiconductor sealing rings:
It is typically made from silicone rubber (VMQ) or polyester film (PET). Selection should be based on the product's actual operating environment and specific requirements. For applications involving high temperatures (>150°C) or exposure to organic solvents, oils, and similar substances, a VMQ sealing ring is recommended. Conversely, for lower-temperature applications or use in dry environments, a PET sealing ring is advised.
In packaged products, the appropriate size of the sealing ring is crucial. An excessively large sealing ring can result in an imperfect seal, while a sealing ring that is too small may fail to ensure proper packaging quality. When measuring the dimensions, it is essential to accurately select the size based on the specific application environment and product specifications.
It should first be laid along the contour line of the sealing ring, and then the components should be placed inside the sealing ring. During installation, care must be taken to avoid stretching or deforming the sealing ring, as this could compromise its sealing performance.
Before encapsulation, perform a visual inspection of the component. If any obvious surface defects, damage, or deformation are detected, replace the component promptly to avoid compromising sealing performance and encapsulation quality. Ensure that the surface remains free from contaminants such as chemical solvents, silicone oil, or other similar substances. During storage, keep the component in a dry, well-ventilated area, and take care to prevent bending or crushing.
The above are the precautions for semiconductor sealing rings. Proper selection and usage can enhance packaging quality and efficiency, while preventing component failures.
