Wiper Control Switch FPC
This wiper control switch FPC is used for in-vehicle signal transmission. Hongyi Precision’s R&D team has developed a mature differential signal routing solution through extensive testing and validation: CAN and LIN communication differential traces strictly adhere to equal-length, equal-spacing, parallel routing; trace spacing ≥3× trace width; impedance remains continuous along the entire route, eliminating impedance discontinuities and stubs—effectively reducing signal interference and ensuring stable in-vehicle communication while minimizing bus error faults.
