High temperature PI film gold-plated foil: a new era in the conductivity of flexible circuit boards

###High temperature PI film gold-plated foil: a new era in the conductivity of flexible circuit boards

In today's rapidly advancing electronic technology, flexible circuit boards (FPCs) have shone in fields such as smart wearables, portable devices, and new energy vehicles due to their advantages of being lightweight, bendable, and highly integrated. However, with the continuous expansion of application fields, higher requirements have been put forward for the stability of the conductivity performance of FPC. In this context, the high-temperature PI film gold-plated foil developed and produced by Advanced Institute (Shenzhen) Technology Co., Ltd. has opened up a new path for the stable conductivity of flexible circuit boards with its unique properties.

####Innovative materials, leading the forefront of technology**

High temperature PI film, also known as polyimide film, is known as the "golden film" due to its excellent high temperature resistance, chemical corrosion resistance, good mechanical properties, and electrical insulation. The gold foil technology, on the other hand, is achieved by uniformly coating a very thin layer of metal gold on the surface of the PI film, which not only enhances the conductivity of the material, but also endows it with excellent oxidation and corrosion resistance. Advanced Institute Technology has perfectly combined these two technologies to create a high-temperature PI film gold-plated foil specifically designed for flexible circuit boards.

**Example witness: In a certain application case of a smart watch, the FPC using traditional PI film is prone to a decrease in conductivity in high temperature environments (such as wearing it on the wrist for a long time in summer), resulting in unstable signals. After switching to the advanced institute's high-temperature PI film and gold foil, even in continuous high-temperature tests above 60 ℃, the conductivity remained stable, the signal transmission efficiency increased by 20%, and the service life of the equipment was significantly extended.

####Stable conductivity performance unlocks more application scenarios**

The stable conductivity of high-temperature PI film coated with gold foil is its core value. It not only solves the problem of conductivity degradation of traditional FPC in high temperature and high humidity environments, but also enables flexible circuit boards to be applied in more complex and diverse scenarios due to their excellent flexibility and durability.

**Data Speaking: In a comparative test for new energy vehicle battery management systems, FPC coated with high-temperature PI film and gold foil showed a 30% reduction in resistance change rate compared to traditional materials over a wide temperature range of -40 ℃ to 85 ℃, ensuring precise control of the battery management system in various extreme environments and effectively improving the safety and endurance of electric vehicles.

####Multi dimensional advantages, shaping new industry benchmarks**

1. * * Efficient heat dissipation * *: The high-temperature PI film itself has good thermal conductivity, combined with the gold foil design, effectively improving the heat dissipation efficiency of the circuit board and reducing the risk of performance degradation caused by overheating.

2. * * Lightweight Design * *: The lightweight characteristics of PI film, combined with an extremely thin gold plating layer, greatly reduce the weight of the entire flexible circuit board while ensuring performance. This is undoubtedly a huge advantage for smart devices that pursue extreme thinness and thinness.

3. * * Environmental sustainability * *: The advanced institute's high-temperature PI film gold foil adopts environmentally friendly processes in the production process, reducing its impact on the environment. At the same time, the recycling rate of gold foil is high, which is in line with the current global advocacy of circular economy concept.

4. * * Enhance product competitiveness * *: Flexible circuit boards using this material provide electronic product manufacturers with differentiated competitive advantages due to their excellent performance stability and innovative technology applications, which helps brands stand out in fierce market competition.

####Future outlook, unlocking infinite possibilities**

With the rapid development of technologies such as 5G, IoT, and artificial intelligence, there is an increasing demand for the intelligence, miniaturization, and integration of electronic devices. As a bridge connecting these high-tech components, the importance of flexible circuit boards is self-evident. The high-temperature PI film gold-plated foil of Advanced Institute, with its unique conductivity stability and multi-dimensional advantages, not only meets the current market demand, but also reserves broad space for the future development of electronic technology.

**Frontier exploration: For example, in the field of foldable displays, the flexibility and conductivity stability of high-temperature PI film coated with gold foil provide the possibility to achieve countless folds of the screen without affecting the display effect, accelerating the commercialization process of foldable screen products such as smartphones and tablets.

In summary, the high-temperature PI film gold-plated foil developed by Advanced Institute (Shenzhen) Technology Co., Ltd. is leading a new round of transformation in the conductivity of flexible circuit boards with its unique innovative concept, solid technical strength, and wide application prospects. In this era of rapid technological advancement, it is not only a breakthrough in technology, but also an exploration and commitment to the infinite possibilities of the future.
