Engineering Solutions
Our Shielded FFC Cables are designed for EMI-sensitive applications where signal integrity matters. From foil and mesh shielding to twisted-pair and impedance-controlled options, we provide custom solutions for USB, LVDS, and high-speed data lines—perfect for medical, industrial, and automotive systems.
Top-Foil Shielded FFC
- 0.5mm / 1.0mm pitch available
- Available in 8 to 60 pins
- Flame-retardant PET + foil laminated surface
This FFC uses a single aluminum foil layer on the top side to reduce external electromagnetic noise. It’s ideal for standard-speed signal transmission in LED lighting, office equipment, and touchscreen modules.
Double-Sided Shielded FFC
- Up to 80 dB EMI suppression (with grounding tab)
- 1.0mm pitch standard; other options available
- Optional stiffeners and folded ends
Foil shielding is applied on both top and bottom surfaces, providing 360° EMI coverage. This is a practical choice for control boards in medical equipment, power modules, and dense industrial assemblies.
Mesh-Braided Shielded FFC
- 100K dynamic bend cycles
- 90–120Ω impedance options available
- Supports twisted signal layout inside
Instead of foil, this FFC features a copper mesh braided layer, allowing excellent shielding and durability under motion. Suitable for robotics, automotive displays, and test rigs that involve continuous movement.
Shielded Twisted Pair FFC（STP-FFC）
- Supports up to 2 Gbps per pair
- 2–8 pair configurations, customizable
- Impedance-matched and EMI tested
This FFC embeds twisted pairs within the flat cable and applies external shielding (foil or mesh). It ensures signal symmetry and minimal crosstalk — a must for camera modules, ADAS, and embedded computing.
Impedance-Controlled Shielded FFC
- 90Ω (LVDS), 100Ω (USB), or custom
- ±10% impedance tolerance
- Length from 50mm to 1000mm; folded options
Designed with precise conductor layout and spacing to control characteristic impedance. When combined with shielding, this type guarantees signal clarity across long runs or temperature variations.
Connector-Integrated Shielded FFC
- Fully tested for insertion force and signal continuity
- Ground tab routing pre-integrated
- Available in tray, bundled or taped packaging
This cable comes with shielding and high-reliability connectors (Molex, Hirose, JAE, etc.) installed on one or both ends. Ideal for high-volume assembly lines where speed and consistency matter.

Frequently Asked Questions
What is a shield cable?
A shield cable refers to any electrical cable with a conductive barrier (foil, mesh, or braid) that encases the inner conductors. This barrier acts as a Faraday cage to absorb or deflect incoming noise and reduce emissions. In flat cables, shielding may be laminated on one or both sides, or embedded within the cable core.
What is shielded cable used for?
Shielded cables are used to prevent electromagnetic interference (EMI) from affecting signal integrity. They’re essential in environments where high-frequency signals run near noisy power sources or RF components. In FFCs, shielding protects display, sensor, and data lines in automotive dashboards, medical imaging devices, and industrial controllers. Sources: IPC-2141A; IEC 61000-4-3.
When should I use shielded cable?
Shielded cables are recommended when signal degradation could result from EMI, crosstalk, or transient voltages. If you’re transmitting high-speed data (e.g. MIPI, LVDS, CAN, USB) or placing FFCs near motors, wireless modules, or switching power supplies, shielding is strongly advised. In FFCs, shielding is critical in high-density layouts or long signal runs.
What types of shielding are available in FFC cables?
FFC shielding options include:
Single-sided aluminum foil (lightweight, cost-effective)
Double-sided foil (for bidirectional EMI exposure)
Braided copper mesh (for dynamic environments)
Shielded twisted pair (for differential signals)
Each type offers varying levels of EMI suppression, bendability, and cost.
Does shielding affect FFC cable flexibility?
Yes, but the impact depends on the shielding structure. Foil-based shielding adds minimal thickness and remains flexible. Mesh braid offers superior EMI performance but reduces flexibility. Hybrid designs (foil + mesh) strike a balance. For frequent movement (e.g. robotic arms), choose reinforced foldable FFCs with dynamic shield layouts.
Can shielded FFC cables support impedance-controlled signals?
Absolutely. Many shielded FFCs are designed for 90Ω–120Ω impedance control, making them suitable for LVDS, eDP, HDMI, and MIPI DSI/CSI signals. Impedance stability is achieved through precise conductor spacing, dielectric selection, and symmetrical layout — shielding helps maintain signal quality under thermal or mechanical stress.
