Among them, Advanced Institute (Shenzhen) Technology Co., Ltd. independently developedPI silver plated film——A composite material that deposits a silver layer on the surface of a polyimide (PI) substrate is reshaping the material application landscape in high-end electronics, aerospace, biomedicine, and other fields due to its unique performance combination and customizable characteristics. This article will analyze the innovative value of this new functional material from three dimensions: technical principles, performance advantages, and application scenarios.

1、 Technological Breakthrough: From Material Composite to Performance Transition

The core innovation of PI silver plated film lies in the deep integration of the high temperature resistance and high strength characteristics of polyimide with the conductivity and thermal conductivity of silver. Advanced Institute has achieved precise control of silver layer thickness from 5 μ m to 125 μ m through the combination of physical vapor deposition (PVD) and chemical plating technology, and can customize special specifications according to customer needs. For example, the PI silver plated film purchased by a well-known new energy vehicle enterprise in Guangdong has a silver layer thickness of only 8 μ m, but it can maintain stability in the extreme temperature range of -269 ℃ to 400 ℃, while meeting the dual requirements of battery management systems for circuit board lightweighting and high conductivity.

2. Thermal management optimization: The thermal conductivity of silver (429 W/) is 1.5 times that of copper, and with the high temperature resistance of PI, it can quickly export heat from electronic devices. Experimental data shows that the performance degradation rate of PI silver plated film is less than 5% after continuous operation at 150 ℃ for 24 hours.

The chemical stability advantage of PI silver plated film is significant in corrosive environments such as chemical and petroleum industries. The silver oxide protective film formed on the surface of the silver layer can resist strong acid corrosion such as hydrochloric acid and sulfuric acid; The PI substrate has excellent tolerance to organic solvents and salt spray. After using PI silver plated film as the sensor electrode material on a certain offshore drilling platform, the equipment failure rate decreased by 60% and the service life was extended to more than 8 years.
