Flexible Flat Cable

Product Overview

Flexible Flat Cable (FFC) is a flat electrical interconnect for connecting boards, displays, modules and other electronic assemblies where compact cable routing is required. Available configurations cover different pitches, conductor counts, lengths, contact arrangements, plating and shielding requirements for OEM and volume orders.

FFC specifications can be selected from established configurations or developed around a customer drawing, existing cable sample, mating connector or defined assembly requirement.

Cable Thickness	Custom	Check connector clearance and available installation space
Contact Configuration	Same-side / opposite-side	Match the contact arrangement and orientation of the mating connector
Conductor Plating	Tin / nickel / gold / silver	Select according to contact and electrical requirements
Shielding	Conductive fabric / aluminum foil / copper foil	Specify when EMI control is required
Reinforcement	Stiffener options	Consider according to connector insertion and handling requirements

How to Select Your FFC Configuration

Start with the mating interface, then confirm the mechanical layout, electrical requirements and any shielding needs.

Connector Interface
Identify the mating connector and confirm its required pitch, contact count, contact side and orientation.

Mechanical Layout
Confirm cable length, available routing space, exit position, bend direction and overall thickness according to the assembly layout.

Electrical Requirements
Define the required conductor arrangement and electrical characteristics based on the circuit and signal requirements.

Shielding Requirements
If EMI control is required, specify the shielding construction together with the cable structure and routing conditions.

Production Reference
For custom development, provide an engineering drawing, existing FFC sample or defined specification as the production reference.

FFC Construction & Key Configurations

Conductor
Parallel copper conductors form the electrical paths. Conductor count and pitch determine the contact layout and overall cable width.

Insulation
Insulating films are laminated around the conductors to form the flat cable body and maintain the required conductor arrangement.

Contact Area
The conductor ends are exposed at the contact area. Contact length and exposed-end arrangement are matched to the mating interface.

Stiffener
A stiffener can be added at the contact end to support insertion and handling during assembly.

Shielding
A shielding layer can be incorporated into the cable structure when the assembly has defined EMI control requirements.

Connector & Interface Compatibility

Connector Matching

Confirm the mating connector model or drawing, contact arrangement, orientation and insertion direction before production. Pitch and conductor count should be verified together with the actual connector interface.

Mechanical Fit

Check cable length, exit position, routing path, bend direction, overall thickness, connector clearance and stiffener position against the available installation space.

Interface Review

Provide the connector model, connector drawing or existing mating FFC where available. For new projects, cable dimensions and electrical requirements can be reviewed together with the connector interface.

Standard & Custom FFC Options

Standard FFC

Established configurations can be quoted directly when the required cable specification is already defined, without new structural development.

Ultrasound Equipment Flexible Flat Cable

Custom FFC

Custom development is available when an existing configuration does not meet the assembly requirement. Drawings, samples or defined specifications can be used as development references.

From Sample to Mass Production

Drawing / Sample Review

An engineering drawing, existing FFC sample or defined specification can be used as the initial production reference.

Prototype Development

The cable structure and required configuration are reviewed before prototype sampling.

First-Article Verification

The first article is checked against the approved reference for dimensions, contact configuration and specified electrical characteristics.

Production Approval

After first-article approval, the confirmed specification is retained as the production reference for batch orders.

Repeat Production

Subsequent orders can follow the approved production reference to maintain the confirmed cable configuration across repeat batches.

Quality Control

Incoming Material Inspection

Copper conductor thickness and insulation film thickness are checked against the specified material requirements. Stiffeners and other supporting materials are also inspected before production.

Process Inspection

Production checks cover conductor alignment, pitch accuracy, cable dimensions and lamination/bonding condition to identify deviations during manufacturing.

First-Article Inspection

The first article is checked against the approved production reference for dimensions, contact configuration and electrical characteristics before batch production.

Production Lot Control

The approved specification and first-article result are used as production references for subsequent batches, with inspection records maintained for the corresponding production lot.

Electrical Testing

Finished FFCs can undergo continuity, conductor resistance, insulation resistance and dielectric withstand testing according to the specified electrical requirements.

Final Inspection

Finished cables are inspected for appearance, dimensions and contact condition before shipment. Packaging is also checked against the order requirements.

FAQ

Q: What information is needed for an FFC quotation?

A: An engineering drawing or specification is preferred. The RFQ should also include the estimated quantity or annual volume and any required compliance documents.

Q: Can you quote an FFC based on an existing sample?

A: Yes. An existing cable sample can be used as a production reference when a complete drawing is not available. Key missing specifications can be confirmed during engineering review.

Q: What is the MOQ for FFC orders?

A: MOQ depends on cable configuration, materials, tooling requirements and order quantity. Lower quantities can be discussed for prototype and pilot orders.

Q: How long does FFC sampling normally take?

A: Sampling time depends on cable structure, tooling requirements and material availability. The confirmed sample schedule is provided after the configuration is reviewed.

Q: What is the typical mass-production lead time?

A: Production lead time depends on order quantity, materials, tooling and cable configuration. The confirmed production schedule is provided with the quotation or order.

Q: What trade terms are available for international FFC orders?

A: Export orders can be discussed under commonly used trade terms such as EXW, FOB and CIF, with the applicable term confirmed during quotation.

Q: Can the same FFC specification be supplied for repeat orders?

A: Yes. The approved first article and production specification can be retained as the reference for subsequent orders, allowing repeat production to follow the confirmed configuration.

Q: Do you support OEM/ODM and private-label orders?

A: Yes. OEM/ODM support covers customized FFC production, prototype development, mass production, and product labeling or packaging requirements for qualified projects.

Q: Can FFC orders be supplied in different quantities for different production stages?

A: Yes. Prototype, pilot and mass-production quantities can be quoted separately according to the project stage and required configuration.

Q: Can packaging requirements be specified for export orders?

A: Yes. Packaging can be specified according to cable protection, quantity and shipment requirements.
