Automotive Flexible Circuit Board Solutions
As vehicles electrify and get smarter, FPC is replacing conventional harnesses across smart cockpits and body control.
Key points
Flexible printed circuits bring light weight, high flex endurance, dense integration and resistance to temperature extremes and vibration, allowing them to replace conventional wiring harnesses across EV powertrain, smart cockpit and body control components. Backed by our IATF 16949 system and automotive process controls, we deliver stable volume production for column switches, electronic shifters, wiper systems and switch assemblies.

Common Causes of FPC Bending Failure in Electronic Shifters and Key Design Verification Points
Open circuits, resistance drift, or unstable contact in electronic shifter FPCs are rarely due to material alone — they result from the combined effects of bending radius, trace routing, stack-up design, stiffener placement, and assembly-induced stress. This article outlines common failure causes and provides a pre-prototyping DFM and reliability validation checklist.

Hongyi Precision has formed a dedicated task force to address poor batch-to-batch consistency in automotive and robotics FPC production, conducting 147 comparative validation tests to optimize material selection, etching parameters, and process control. New measures include SPC real-time monitoring, AOI microscopic scanning, and simulated flexure testing, alongside an exception root-cause closed-loop mechanism. Mass-production yield improved to 98.7%, failure rate after 100,000 flex cycles dropped by 86%, and latent open-circuit complaints decreased by 79%.
