Polyimide (PI) film is currently the largest area of ??application of flexible printed circuit board. With the rapid development of electronic products with rapid changes, the electronic assembly technology posed one after another harsh challenges. In order to be able to cater to the development of electronic technology, people have made bold innovations in the field of electronic assembly technology. In this context, a flexible circuit (flexible circuit) made of thin, flexible polymer film with delicate wires, Instead, it adapts to surface mount technology and can be bent into countless shapes.
Polyimide film has high and low temperature (-269 ~ 400 ℃), high friction, self-lubricating, high strength, high insulation, radiation resistance, corrosion resistance, thermal expansion coefficient, organic solvents, self-extinguishing, non-toxic Comprehensive performance. Polyimide film part of the long-term operating temperature above 350 ℃, short-term up to 450 ℃, is the best engineering plastics temperature resistance of engineering plastics, its comprehensive performance is also unmatched by other special engineering plastics, the world Known as "experts to solve the problem," widely used in aerospace, aerospace, mechanical, electrical, atomic energy, microelectronics, liquid crystal display and other high-tech fields.
