With the rapid development of modern electronic and electrical technology, the requirements for packaging materials are becoming increasingly strict.Aluminum coated PI filmAs a high-performance composite material, it has demonstrated unique advantages in the field of electronic and electrical packaging. This article will delve into the safety standards of aluminum coated PI film in electronic and electrical packaging, and analyze them in conjunction with the practical application of Advanced Institute (Shenzhen) Technology Co., Ltd.

1、 Basic characteristics of aluminum coated PI film

PI (polyimide) film aluminum plating is a composite material in which a high-purity aluminum layer is uniformly deposited on the surface of a high-performance PI film through vacuum evaporation technology. This material combines the excellent performance of PI film with the good conductivity, reflectivity, and barrier properties of aluminum coating, providing a high-performance solution for electronic and electrical packaging.

1. Excellent high temperature resistance: PI film can maintain its physical and chemical stability at extremely high temperatures, and this characteristic is still retained after aluminum plating. According to testing, PI aluminum plated film can be used for a long time in an environment above 200 ℃ without performance degradation.

2. Excellent chemical corrosion resistance: PI film has good resistance to most organic solvents, acids, alkalis, etc., and the aluminum plating layer further enhances its corrosion resistance. Experiments have shown that after immersion in various corrosive media for 24 hours, the surface of PI aluminum plated film remains smooth and undamaged.

3. High reflectivity: The aluminum coating has high reflectivity and can effectively reflect light or electromagnetic waves. Test data shows that the reflectivity of PI aluminum plated film can reach over 90%, making it an ideal reflective material.

4. Good conductivity: The aluminum coating endows the PI film with certain conductivity, making it significantly advantageous in electromagnetic shielding, anti-static, and other aspects. The test results show that the conductivity of PI aluminum plated film is superior to traditional metal thin films, and the resistivity can be reduced to 10 ^ -6 Ω· cm.

5. Good barrier properties: The aluminum plating layer has a good barrier effect on gases, moisture, etc. Experiments have shown that,PI aluminum plated filmAfter being placed in an environment with a humidity of 90% for 72 hours, there was no significant change in the moisture content inside.

2、 Application of Aluminum Plated PI Film in Electronic and Electrical Packaging

1. Electromagnetic shielding: The high conductivity of PI aluminum plated film makes it an ideal material for electromagnetic shielding. In electronic product packaging, PI aluminum plated film is widely used in the manufacturing of electromagnetic shielding covers, effectively reducing electromagnetic interference and improving product stability and reliability.

2. Anti static: In the process of electronic and electrical packaging, electrostatic discharge (ESD) is an issue that cannot be ignored. PI aluminum plated film has good anti-static performance, which can effectively prevent damage to electronic components caused by electrostatic discharge. occupyAdvanced Institute (Shenzhen) Technology Co., LtdThe test data shows that electronic products packaged with PI aluminum plated film have an electrostatic discharge test pass rate of over 99%.

3. High barrier packaging: The excellent barrier effect of PI aluminum film on gas and moisture makes it the preferred choice for high barrier packaging materials. In the electronic product packaging of Advanced Institute (Shenzhen) Technology Co., Ltd., PI aluminum plated film is widely used in moisture-proof and oxidation resistant packaging, effectively extending the shelf life of the products.

3、 Safety standard for aluminum coated PI film in electronic and electrical packaging

1. Material safety: PI aluminum plated film should comply with relevant national safety standards, such as RoHS (Restriction of Hazardous Substances Directive), REACH (EU Chemical Registration, Evaluation, Licensing and Restriction Regulation), etc., to ensure that the material will not cause harm to human health and the environment during use.

2. Process safety: In the preparation and packaging process of PI aluminum plating film, process parameters such as vacuum degree, coating rate, temperature, etc. should be strictly controlled to ensure product quality and safety. Advanced Institute (Shenzhen) Technology Co., Ltd. adopts advanced vacuum evaporation technology and ensures the quality and safety of PI aluminum plating film through precise control of process parameters.

3. Safety of use: When using PI aluminum plated film for electronic and electrical packaging, it is necessary to strictly follow the product manual and operating procedures to avoid improper operations such as excessive bending, scratching, or high-temperature baking, ensuring the safety of product use.
