Application and Performance Analysis of Gold Plated Film in Electronic Industry

With the rapid development of the electronics industry, the requirements for materials are also increasing day by day. Gold plated films are becoming increasingly widely used in the electronics industry due to their excellent conductivity, corrosion resistance, and ease of soldering. This article will explore the main applications of gold plating film in the electronics industry and compare different materialsGold-plated filmTo demonstrate its importance, its performance should be taken into account.

Application areas of gold-plated film

Gold plating film is commonly used on key components such as electronic connectors, printed circuit boards (PCBs), integrated circuit (IC) pins, contact switches, etc., to ensure the reliability and long-term stability of electrical connections. Especially in high-frequency signal transmission, gold plating film can reduce signal loss and improve transmission efficiency.

Comparison between PI Gold Plated Film and PET Gold Plated Film

In order to gain a deeper understanding of the performance differences of gold-plated films, we selected two common substrates - polyimide (PI) and polyethylene terephthalate (PET) - and conducted detailed performance tests on their gold-plated films.

Experimental Design and Methods

This study was supported by Advanced Institute (Shenzhen) Technology Co., Ltd. and prepared using standard electroplating processesPI gold-plated film and PET gold-plated filmSample. The sample thickness is controlled at 0.5 μ m, and then its resistivity, corrosion resistance, and mechanical strength are tested separately.

Data Results

• Electrical resistivity: According to the test results, the electrical resistivity of PI gold-plated film is 0.1 μ Ω· cm, while that of PET gold-plated film is 0.12 μ Ω· cm. Although there is not much difference between the two, in precision electronic devices, this small difference can significantly affect product performance.
• Corrosion resistance: Through salt spray testing, it was found that the PI gold plating film showed no significant changes after continuous exposure to salt spray environment for 72 hours, while the PET gold plating film exhibited slight oxidation.
• Mechanical strength: Tensile tests show that the fracture strength of PI gold-plated film is 18MPa, which is better than the 16MPa of PET gold-plated film.

analysis and discussion

From the above data, it can be seen that,PI gold-plated filmIt is superior to PET gold plating film in terms of resistivity, corrosion resistance, and mechanical strength. This is mainly because PI materials themselves have better thermal and chemical stability, making them more suitable as gold plating film substrates for high-performance electronic products.

conclusion

The importance of gold plating film in the electronics industry is self-evident, and choosing the appropriate substrate is crucial for improving product quality. This study suggests that in certain demanding applications, PI gold-plated film may be a better choice than PET gold-plated film. However, in practical applications, factors such as cost and processing difficulty need to be considered, so enterprises should take into account a comprehensive approach when selecting.
