The chip is an important basic component of the information technology industry, and today, the "lack of core" affects the development of a number of global technology industries. With the rapid development of 5G communication, Internet of Things, artificial intelligence and other technologies, semiconductor technology is also facing new challenges and opportunities.
How to improve the performance of semiconductor equipment, reduce costs, and achieve better energy efficiency has become a hot topic in the industry. In this process, the importance of plastics as invisible guardians throughout the semiconductor process cannot be ignored.
In recent years, the attention to "electronic semiconductors" on various search engines has continued to rise. People generally pay attention to the development trend of electronic semiconductor technology, application fields and future market prospects. At the same time, materials and devices in electronic semiconductor manufacturing have also attracted widespread attention.
Among these key materials, plastics film, especially ETFE (ethylene-tetrafluoroethylene copolymer)film, has attracted much attention due to their unique properties.
ETFE (ethylene-tetrafluoroethylene copolymer)film is a colorless transparent polymer material with many excellent properties:
Thickness and quality: The thickness of ETFE film is usually between 0.105 and 0.125 mm. With the increase of thickness, the film will be harder and more brittle, difficult to process. The density of ETFE film is about 1175 g/ cm3. Taking 0.20mm thick ETFE film as an example, the light transmittance of single-layer transparent film structural material is as high as 95%, and the white film structural material is 50% ~ 55%.
Durability: ETFE film has very high anti-aging ability, and the service life is more than 25 years.
Color and transmittance: ETFE film is usually colorless and transparent, and can also be used as white. Taking 0.20mm thick ETFE film as an example, the light transmittance of single-layer transparent film structural material is as high as 95%, and that of white film structural material is 50% ~ 55%.
Fireproof performance: ETFE film structural material is flame retardant material, ETFE film structural material will shrink after hot melt, but there is no drip. Because the ETFE film structure material is very thin and light, it is very harmful in case of fire.
Tensile strength: The tensile strength of ETFE film is greater than 40 MPa.
Stress-strain relation: When the tensile stress is below 20 MPa at normal temperature, the ETFE film has complete elastic properties, and the tensile modulus reaches 800 ~ 1,000 MPa; When the tensile stress is near 25 MPa, there will be a yield point, and then it will enter the plastic strengthening stage until it breaks.
Elongation at break: The elongation at break of ETFE film is more than 300%.
ETFE film plays an important role in the manufacture of electronic semiconductors. It has many unique properties, such as chemical corrosion resistance, excellent insulation properties and high temperature resistance. These properties make ETFE film one of the ideal materials for electronic semiconductor manufacturing. Whether it is chip packaging, circuit board manufacturing, connector manufacturing, clean room equipment manufacturing or optical component manufacturing, ETFE film plays an important role.
By using ETFE film as the packaging material, the chip can be protected from the impact of the environment, improving the stability and reliability of the product. In circuit board manufacturing, ETFE film as an insulating material can effectively improve the reliability and stability of circuit boards.
In connector manufacturing, the use of ETFE film as a connector material can improve the service life and reliability of connectors. In the manufacture of clean room equipment, ETFE film can improve the cleanliness of the production environment due to its smooth surface and no particles. In the manufacture of optical components, ETFE film is widely used due to its transparency and chemical resistance.
With the continuous progress of science and technology, the requirements for material performance in the electronic semiconductor industry are also increasing.
As a kind of high performance plastic material, ETFE film has a broad application prospect in the field of electronic semiconductors. In the future, with the continuous emergence of new technologies and the development of the industry, high-performance plastics such as ETFE film will play a more important role, providing strong support for the progress of the electronic semiconductor industry.
