PI Gold Plated Film: A New Generation of Highly Reliable Conductive Materials Empowering AI Servers, Advanced Packaging, and Flexible Electronics

1、 AI era drives PI gold plating film to embrace new development opportunities

In recent years, the rapid development of generative AI, large model training, and high-performance computing has led to increasing demands for signal integrity, conductivity stability, and material reliability in AI servers, high-speed switching equipment, and advanced semiconductor packaging. At the same time, emerging industries such as flexible displays, wearable devices, medical electronics, and new energy vehicles continue to expand, driving rapid growth in the flexible electronic materials market.

PI material itself has excellent high temperature resistance, insulation performance, dimensional stability, and mechanical strength, and is one of the most commonly used high-performance substrates in flexible electronics. By depositing a high-purity gold layer on the surface of PI thin films, the material can be further endowed with excellent conductivity, oxidation resistance, and long-term reliability, combining the dual advantages of flexible substrates and precious metal conductors. It has broad application prospects in high-speed interconnection, microelectronic packaging, and highly reliable electronic systems. In recent years, PI metalized films have been widely used in fields such as flexible electronics, wearable devices, high-density interconnects, and advanced packaging.

2、 Core performance advantages of PI gold-plated film

PI gold plating film can balance the advantages of flexible substrates and precious metal materials, maintaining stable performance in complex electronic environments.

Firstly, the gold layer has excellent conductivity and extremely low contact resistance, which can meet the requirements of high-speed signal transmission and precision electronic interconnection. At the same time, gold materials have good antioxidant capacity, and even if exposed to high humidity, high temperature, or complex environments for a long time, they can still maintain stable conductivity, significantly improving the service life of electronic products.

Secondly, PI substrate has excellent high temperature resistance, which can adapt to high-temperature process environments such as SMT reflow soldering and advanced packaging, and maintain good dimensional stability, making it less prone to warping or deformation, providing reliable guarantee for high-precision manufacturing.

In addition, PI gold-plated film has excellent flexibility and can maintain stable conductivity even under repeated bending, curling, and dynamic working conditions, making it very suitable for flexible circuit boards (FPCs), foldable electronic products, and new generation flexible smart terminals.

For high-end electronic manufacturing, material adhesion is equally crucial. Advanced Institute Technology optimizes surface treatment and vacuum coating processes to form a stable bond between the metal layer and PI substrate, improving product bending resistance and long-term reliability, and providing stable support for complex application environments. Related studies have shown that optimizing PI surface modification and metallization processes can significantly improve the adhesion and flexibility reliability of metal layers.

3、 Advanced manufacturing technology ensures product stability

Advanced Institute Technology has established a comprehensive production system for flexible substrate coating, adopting advanced vacuum coating (PVD) and roll to roll continuous production technology to achieve continuous metalization manufacturing of PI thin films.

The company continues to optimize coating uniformity, film thickness control, and interface bonding processes, effectively improving product adhesion and durability while ensuring high conductivity. We can provide PI gold-plated film products with different thicknesses, sizes, and structures according to customer needs.

At the same time, the company's independently developed continuous production technology for electromagnetic heating rollers can further improve the consistency of coating, ensuring stable quality of products during mass production and providing reliable guarantees for consumer electronics, automotive electronics, and industrial electronics customers.

4、 Typical application areas

With the continuous upgrading of electronic products, PI gold plating film is playing an important role in multiple high-end fields.

In AI servers and data centers, high-speed GPUs, switches, and high-speed connectors require stable and reliable conductive interconnect materials. PI gold-plated film can meet the requirements of high-speed signal transmission and long-term operation.

In the field of flexible electronics, PI gold-plated film is widely used in flexible printed circuit boards (FPCs), foldable screen terminals, wearable devices, and intelligent medical electronics, providing lightweight and highly reliable conductive solutions for products.

In the field of advanced semiconductor packaging, with the development of Chiplets, high-density packaging, and advanced interconnect technologies, the demand for high-precision flexible metallization materials continues to grow, and PI gold plating film is becoming one of the important basic materials.

In addition, PI gold plating film is widely used in aerospace, high-end communication equipment, precision sensors, and new energy vehicle electronic systems due to its high temperature resistance, high reliability, and corrosion resistance. PI thin film materials are currently widely used in industries such as FPC, OLED displays, semiconductors, and new energy vehicles, and continue to expand into the fields of AI and high-end electronics.
