The emergence of flexible circuit boards is to meet the needs of modern electronic products for characteristics such as lightness, softness, and bending resistance, as well as to promote innovation and development in electronic product design.
         The emergence of flexible circuit boards stems from the demand for electronic products to be lighter, softer, and more resistant to bending, as well as the pursuit of more complex and innovative product designs. The following are several reasons for the appearance of flexible circuit boards:
1. Space limitation: Traditional hard board circuit boards have limitations in terms of space limitation, especially for products that require curved design or electronic components arranged in limited space. Flexible circuit boards can be bent and folded more easily, providing more design freedom in limited space.
2. Weight and thickness requirements: Some application scenarios have strict requirements for the weight and thickness of electronic products, such as wearable devices and mobile devices. Flexible circuit boards, due to their thin substrate, can help reduce the overall weight and thickness of the product while providing the required circuit functions.
3. Durability and reliability: Flexible circuit boards have high bending and impact resistance. In contrast, traditional hard board circuit boards are more susceptible to damage when subjected to external impacts or bending. Therefore, in applications that require higher durability and reliability, flexible circuit boards have more advantages.
4. Adaptation to special environments: The materials of flexible circuit boards usually have high temperature and humidity resistance, making them more suitable for applications in some special environments, such as automotive electronic systems, medical equipment, and aerospace electronic equipment.
5. Innovative design demand: With the increasing demand from consumers for personalized and innovative products, product designers need more flexible electronic component layouts and design options. The emergence of flexible circuit boards has provided them with more possibilities and promoted the birth of innovative products.
