Gold plated PI conductive film material

2. Can be reflow soldered

3. Excellent heat resistance

4. Excellent environmental durability

5. Excellent super bending resistance

Ordinary conductive fabrics are mostly plated with nickel after copper plating, while gold-plated conductive fabrics are coated with 99.9% pure gold, and there are multiple options available, including substrate and gold plating composition. Gold is innate in nature and has no allergic reactions to the human body. It shines brightly and has a very good decorative effect when used in exposed situations.

According to the customer's needs,Gold plated conductive clothMany new varieties have been developed. Gold plated conductive cloth not only has better performance and appearance, but also can be reasonably configured with finished gold plating components according to the needs of different occasions, greatly reducing costs; At present, a product series has been formed, divided by thickness, base material, and gold plating composition, including 24K gold, 18K gold, 16K gold, 14K gold, DTY multi strand fine yarn woven fabric surface. Different thicknesses, substrates, and gold plating are particularly effective in reducing batch burrs

The difference between gold-plated conductive cloth and general conductive cloth lies in the metal coating: the metal coating of general conductive cloth is copper nickel; Gold plated conductive cloth is made of gold.

There is not much difference between the two types of conductive fabrics on polyester fabric base, but the cost on the coating is much different. Generally speaking, the price of gold-plated conductive cloth is several times higher than that of ordinary conductive cloth. Moreover, gold-plated conductive cloth is not a mass-produced product in the market and can only be ordered from factories. This is bound to be much higher in minimum order quantity than general conductive fabrics. Therefore, it is not a special requirement, and the conductive cloth is still mainly coated with copper nickel.

    PI film gold platingNamely, polyimide films, including two types: homopolymer polyimide films and biphenyl polyimide films. Polyimide film has the highest UL-94 flame retardant rating, good electrical insulation performance, mechanical properties, chemical stability, aging resistance, radiation resistance, low dielectric loss, and these properties do not show significant changes over a wide temperature range (-269-400 ℃). It is formed by the condensation of phthalic anhydride dianhydride (PMDA) and diaminodiphenyl ether (DDE) in a strongly polar solvent to form a film, which is then imidized. Yellow transparent, with a relative density of 1.39-1.45. Specially suitable for flexible printed circuit boards and substrates made of various high-temperature resistant electrical insulation materials.

PI film was successfully developed in the 1960s by DUPONT, a world-renowned photosensitive material company and one of the main suppliers of photosensitive film substrates. It was originally mainly used in the field of insulating films. With the rapid development of global science and technology, especially since entering the information age, the application scope of PI film has been greatly expanded, such as in the fields of electrical engineering, electronics, rail transit, aerospace, etc.
However, due to being a high-tech barrier industry, the global PI film production capacity is still mainly monopolized by a few foreign companies, including DuPont from the United States, Zhonghua from Japan, SKPI from South Korea, and Ube Industries from Japan, with an overall production capacity of 2000-3000 tons per year.

The main technical barriers of PI film lie in the long equipment customization cycle, high process difficulty, high degree of customization, and scarcity of technical talents. In addition, the investment scale of PI film should not be underestimated. Investing in a production line requires 200-300 million yuan. Although the investment scale is not large, the risk is high, the investment cycle is long, and it is not affordable for ordinary enterprises.
