Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a bending-resistant circuit board. Background Technology

[0002] Bending-resistant circuit boards (PCBs) address the shortcomings of existing flexible circuit boards, the need to improve their stability and durability, and the special requirements for bending resistance in specific applications. As electronic devices become smaller and more multifunctional, the stability and durability of PCBs become paramount. Traditional PCB materials and designs are insufficient to meet the high-performance requirements of modern electronic products, particularly in wearable devices, medical devices, and aerospace. These fields place higher demands on the bending resistance and environmental adaptability of PCBs. In specialized applications such as wearable devices, medical devices, automotive electronics, and aerospace, PCBs often need to operate under bending or dynamic stress conditions. These applications require PCBs to possess not only excellent electrical properties but also sufficient mechanical strength to resist bending and torsion, ensuring the reliability and long-term stability of the devices.

[0003] Due to issues with the materials and manufacturing methods of the circuit board itself, as well as other circuit board installation problems, circuit boards are prone to warping and other phenomena. Most existing circuit boards are easily damaged during use, have poor bending flexibility, and lack sufficient mechanical strength to resist bending and twisting. Therefore, we propose a bend-resistant circuit board to solve this problem. Utility Model Content
