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.

How to Select an FPC Connector? Parameters R&D and Procurement Teams Must Confirm
A connector must simultaneously match the FPC’s contact configuration, thickness, stiffener, trace count, signal type, and available assembly space. Even if the FPC itself is electrically sound, mismatched models may cause insertion difficulty, unstable contact, or inconsistent mass-production assembly.

Automotive flexible printed circuits (FPCs) must simultaneously withstand temperature fluctuations, continuous vibration, assembly-induced bending, and complex signal transmission. This article outlines pre-prototyping design verification points for automotive FPCs—from material stack-up and dynamic/static bend zoning to reinforcement strategies, CAN/LIN routing, and reliability validation.
Learn moreTechnical InsightsCommon 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.
