AI Technical Summary
Technical Problem
During the bending process, there is a length difference between the inner and outer layers of a multilayer flexible circuit board, which affects the impedance parameters of the circuit board and makes it prone to cracking.
Method used
The design incorporates a rigid-flexible integrated circuit board based on a gradient transition structure, employing length adjustment components and bending limiters to adjust the relative lengths between the flexible layers and to limit excessive bending through the bending limiters.
Benefits of technology
Ensuring that the length of each flexible panel is consistent after bending improves the bending reliability of the flexible panel, avoids breakage, and has strong practicality and promotional significance.
