The Characteristics of PI Materials and the Necessity of Copper and Silver Plating

Excellent characteristics of PI materials

PI has a series of remarkable features. It has extremely high temperature resistance and can maintain stable physical and chemical properties in long-term high-temperature environments. Its glass transition temperature is usually above 260 ℃, and its short-term use temperature can even reach up to 400 ℃. At the same time, PI also has good insulation performance, with a volume resistivity of over 10 ¹⁷Ω· cm, and a low dielectric constant and dielectric loss over a wide frequency range, making it an ideal insulation material in the field of electronics and electrical engineering. In addition, PI also has excellent mechanical properties such as high strength, high modulus, and good flexibility, which can withstand large mechanical stresses without damage.

The necessity of copper and silver plating

Although PI materials themselves have excellent performance, there are still some limitations in certain specific application scenarios. For example, in situations where good conductivity is required, the insulation performance of PI becomes a limiting factor. Copper and silver, as two excellent conductive metals, have extremely high electrical conductivityCopper and silver plating on the surface of PIIt can endow PI materials with good conductivity, enabling them to meet the needs of electronic circuits, electromagnetic shielding, and other aspects. Meanwhile, copper and silver plating can also improve the welding performance of PI materials and enhance their connection reliability with metal components. In addition, silver also has excellent antioxidant and antibacterial properties, and the silver plated PI material has better stability and durability in certain special environments.

Due to the high chemical inertness of the PI surface, it is difficult to achieve good adhesion by directly plating metal. The company's R&D team uses methods such as chemical etching and plasma treatment to activate the surface of PI, increasing its surface roughness and chemical activity, thereby improving the adhesion between the metal coating and the PI substrate. For example, the chemical etching process forms tiny pits and holes on the surface of PI by selecting appropriate etchants and etching conditions, providing more attachment points for the deposition of metal atoms and effectively improving the adhesion of the coating.

Accurate coating control technology

In the process of copper and silver plating, Advanced Institute (Shenzhen) Technology Co., Ltd. has mastered precise coating control technology. The company adopts advanced electroplating and chemical plating processes, which can accurately control the thickness, uniformity, and composition of the coating. By optimizing the formula and plating parameters of the plating solution, such as current density, temperature, time, etc., uniform deposition of copper and silver coatings has been achieved, ensuring consistency in coating thickness. At the same time, the company can adjust the composition ratio of the coating according to different customer needs. For example, in copper silver alloy coatings, by controlling the content of copper and silver, coatings with specific conductivity, wear resistance, and corrosion resistance can be obtained.

Research and development of environmentally friendly plating solution

With the continuous improvement of environmental awareness, Advanced Institute (Shenzhen) Technology Co., Ltd. attaches great importance to the environmental performance of plating solutions. The company's R&D team is committed to developing environmentally friendly plating solutions that reduce the use of heavy metal ions and harmful chemicals in traditional plating solutions. For example, the new chemical copper plating solution and chemical silver plating solution developed by the company adopt cyanide free and low toxicity formulas, reducing environmental pollution and health hazards to operators. At the same time, the company has also established a comprehensive plating solution recovery and regeneration system, achieving the recycling of plating solution, reducing production costs, and improving resource utilization efficiency.
