It is a printed circuit board made of flexible materials such as polyimide or polyester film. It is designed by embedding a circuit on a thin and lightweight plastic sheet that can be bent and folded at will. Its structural composition mainly includes:
Insulating film: forming the base layer of the circuit, commonly used polyimide or polyester material. Polyimide materials have the characteristics of non-flammability, geometric stability, high tear strength, and can withstand welding temperatures. The physical properties of polyester materials are similar to those of polyimide, with low dielectric constant, low hygroscopicity and high temperature resistance
Product Advantages:
High flexibility: It can be freely bent, wound and folded, and can be arranged, moved and expanded arbitrarily according to the requirements of the complex space layout inside the energy storage equipment, so as to realize the integration of component assembly and wire connection and optimize space utilization.
- Lightweight and portable: light weight and thin thickness, which can greatly reduce the volume and weight of energy storage equipment, which is in line with the trend of energy storage products to miniaturization and lightweight, and is convenient for transportation and installation.
- Good electrical performance: It has good heat dissipation and weldability, stable signal transmission, can effectively reduce electromagnetic interference, and ensure the stable operation of the energy storage system.
- Adapt to complex environments: The substrate and material characteristics make it have good high temperature resistance, chemical corrosion resistance, vibration resistance and impact resistance, and can work stably under harsh environmental conditions.
- Design and manufacturing advantages: high-density wiring can be realized to meet the requirements of high integration of energy storage systems; The combination of software and hardware design makes up for the lack of bearing capacity of flexible substrate elements to a certain extent. Some production processes, such as the continuous reel-to-reel production process with FDC technology, simplify processes, increase efficiency, and reduce costs
A brief introduction to the development trend
