[0002] Flexible circuit boards are highly reliable and highly flexible printed circuit boards made of polyimide or polyester film as the substrate. They have the characteristics of high wiring density, light weight, thin thickness, good bending properties, and can be bent, wound, and folded freely. Compared with traditional rigid circuit boards, flexible circuit boards have better flexibility and shock resistance, can adapt to design requirements of various shapes and sizes, and can realize complex circuit designs in a small space. Due to their lightness, flexibility, good shock resistance and impact resistance, flexible circuit boards are widely used in mobile devices, automotive electronics, medical equipment, industrial control and automation, and LED lighting. In these applications, the circuit board may be subjected to vibration, impact or other forms of mechanical stress. If there are no effective anti-deformation measures, the shape and structure of the circuit board may change, resulting in circuit disconnection or short circuit, which in turn affects the normal operation of the entire system. Therefore, an anti-deformation flexible circuit board is needed. Utility Model Content
