With the rapid development of microelectronics technology, higher requirements have been put forward for the electrical connection and heat dissipation performance of electronic components. Silver plated film, as a high-performance functional thin film material, plays an increasingly important role in microelectronic packaging. This article will delve into how silver plated films ensure good electrical connections and heat dissipation performance in microelectronic packaging, and with reference to data and examples, specifically mentioning the advanced research institute (Shenzhen) Technology Co., LtdAdvanced Institute Technology PI Silver Plated Film.

1、 The role of silver plated film in electrical connections

1. High conductivity

Silver, as an excellent conductor, has extremely low electrical resistivity and excellent conductivity. Silver plated film can significantly reduce contact resistance and improve the transmission efficiency of electrical signals by forming a uniform silver layer on the surface of microelectronic components. According to experimental data, the conductivity of silver plated film can reach up to 6.3 × 10 ^ 7 S/m, which is much higher than other commonly used metal materials, ensuring stable electrical connections in microelectronic packaging.

2. Reliability enhancement

Silver plated film not only provides excellent conductivity, but also enhances the reliability of microelectronic packaging. Traditional metal connection methods may cause poor contact due to oxidation, corrosion, and other reasons, while silver plated films have good oxidation resistance and corrosion resistance, which can effectively extend the service life of electronic components. In addition,PI silver plated filmIt can also increase the mechanical strength of the contact surface and improve the stability of the connection.

Silver has excellent thermal conductivity, with a thermal conductivity of approximately 429 W/(m · K), which is several times that of copper. In microelectronic packaging,PI silver plated filmIt can effectively reduce the operating temperature of components and improve heat dissipation efficiency. Especially in high power density electronic components, the application of silver plated films is particularly important. Experimental data shows that electronic components packaged with silver plated film can reduce their operating temperature by about 20% compared to non silver plated components, significantly improving the stability and reliability of the components.

2. Uniform heat dissipation

Silver plated film can form a uniform thermal conductive layer, allowing heat to be evenly distributed on the surface of the component and quickly conducted to the heat dissipation device. This uniform heat dissipation characteristic helps reduce thermal stress concentration and prevent component damage due to local overheating. At the same time, silver plated film can also improve the thermal contact efficiency between the heat dissipation device and the components, further reducing the heat dissipation resistance.
