Custom FFC & Ribbon Cable Assemblies
WireLoomTech manufactures custom FFC cable assemblies (flat flexible cables) and IDC ribbon cable assemblies for electronic equipment, display modules, industrial controls and OEM production.
From exposed-contact FFC jumpers and reinforced or folded cables to IDC-terminated ribbon assemblies, products are manufactured to customer-defined conductor arrangements, connector interfaces, finished dimensions and installation requirements.
We review drawings, existing samples, connector part numbers and technical specifications, with sample confirmation where required for repeat manufacturing.
Two Flat Cable Systems. Different Connection Methods.
FFC and traditional round-conductor ribbon cable both support organized internal electrical connections, but their conductor construction, mating interfaces and termination processes differ.
Flat Flexible Cable (FFC)
FFC typically uses parallel flat conductors laminated within thin insulating films. Prepared contact areas at the cable ends connect directly to compatible FFC/FPC interfaces.
Ribbon Cable & IDC Assemblies
Traditional ribbon cable uses individually insulated conductors arranged side by side. Assemblies can incorporate compatible IDC connectors, separated-wire ends or other specified terminations.
Conductor Geometry & Finished Cable Specifications
An FFC cannot be defined by overall length and contact count alone. Conductor dimensions, insulation structure and controlled reference measurements must match the intended electrical interface.
Pitch & Circuit Count
Pitch is the center-to-center distance between adjacent conductors. Common FFC designs include 0.5 mm and 1.0 mm pitch; other options depend on the cable system. Circuit count must match the required electrical paths.
Width, Thickness & Material
Conductor geometry affects electrical characteristics and mechanical performance. Cable width also depends on conductor count, pitch and edge margins; it should be specified independently.
Laminated Construction
Flat metallic conductors are laminated between insulating films. Material systems may include polyester or polyimide-based films, subject to the required finished cable specification.
Length & Datums
Specify whether finished length is measured between conductor tips, cable edges or other defined features, including tolerances and the required overall width.
Contact Finish
Exposed contacts may use finishes such as tin or gold depending on the selected cable system and mating connector requirements.
Electrical & Environmental Limits
Voltage, current, temperature and environmental requirements are evaluated for the specified cable and connector combination. No universal rating applies to every FFC construction.
Contact Orientation, Exposed Ends & Stiffeners
Two FFC cables with the same pitch, circuit count and length can still be incompatible when their contact faces or reinforced-end dimensions differ.
Same-Side Contacts
With the cable in a defined flat orientation, exposed contacts at both ends face the same side. The mating connectors must engage those contact faces.
Opposite-Side Contacts
The exposed contact surface at one end faces the opposite side from the other end. Selection depends on connector contact positions and the installation route.
Exposed Contact Dimensions
Define exposed conductor length, width and position to suit the connector's insertion depth and electrical engagement requirements.
End Stiffeners & Thickness
Specify the support strip's material, length, thickness, position and orientation. The complete reinforced end must meet the connector's insertion-thickness requirements.
Retention & Identification
Where required, define retention notches or ears, end references, conductor identification and orientation features according to the connector drawings.
Connector Compatibility Is More Than Matching Pitch
FFC/FPC connectors differ in contact position, cable-end thickness, insertion method and mechanical retention. These details must match the finished FFC end.
Concept: FFC insertion & contact position
Illustrative functional interface only. Actual connector contact position, actuator design and insertion geometry vary by part number.
ZIF, LIF & Other Types
Connectors may use zero-insertion-force, low-insertion-force or other insertion arrangements. Follow the selected connector's actuator, engagement and removal instructions.
Top / Bottom Contact
Contact locations can engage the top, bottom or both faces of the inserted cable. The FFC's exposed surface must align with the intended connector contacts.
Insertion Geometry
Confirm reinforced-end thickness, contact dimensions, insertion depth, alignment and permitted cable width using the mating connector datasheet.
Retention & Routing
Locking ears, notches and board placement can affect end design and routing. Check both connection ends and avoid applying excess stress at the connector entrance.
Folding, Flexibility & Shielding
FFC can be adapted for constrained equipment layouts and defined electrical conditions, provided the chosen construction is suitable for the intended mechanical duty.
90° Fold
Changes cable direction to suit installation space.
Z Fold
Offsets connection points within a defined route.
Crank Fold
Creates an angled routing offset.
180° Fold
Folds cable back within a compatible installation.
Static Bending vs. Repeated Movement
A cable folded during assembly is not automatically suitable for continuous movement. Dynamic applications require an appropriately evaluated construction, bend radius, movement path and expected flex cycles. Routing should avoid excess load on connector contacts and retention features.
Shielding & Special Materials
Project-defined FFC may incorporate shielding, grounding features, special insulation or contact finishes. Shield coverage, grounding points and verification must match the electrical design; adding a conductive layer alone does not establish EMI performance.
Round-Conductor Ribbon Cable Assemblies
Unlike laminated FFC, traditional ribbon cable contains individually insulated round conductors in a parallel flat arrangement. Its assembly specifications are based on wire structure, conductor spacing and compatible termination systems.
Cable Size & Connector Pitch Are Different Parameters
A common IDC ribbon system uses 28 AWG conductors at 1.27 mm (0.050 in.) center spacing, although other constructions exist.
Ribbon conductor spacing and connector contact pitch are not necessarily the same: certain 2.54 mm dual-row IDC systems use ribbon cable with 1.27 mm conductor spacing. The approved cable/connector combination determines compatibility.
This page focuses on prepared and terminated ribbon assemblies, not standalone bulk ribbon cable materials.
Wire & Insulation
Define AWG, conductor construction, insulation material, conductor count, center spacing and finished dimensions for the selected ribbon system.
Controlled Connector Assembly
IDC contacts connect to compatible insulated conductors through the specified termination process. Confirm cable alignment, tooling, connector position and strain relief.
Specified Connection Points
Build single-ended or IDC-to-IDC assemblies, selected alternate end preparations or compatible multiple-connector forms. Review connector keying, polarization and strain relief where applicable.
Pin 1, Polarity & Wiring Assignment
An edge marking may help identify conductor 1, but its meaning and the pin numbering convention must follow the actual connector system. Drawings should establish connector orientation, viewing direction and conductor-to-contact mapping, including both ends where applicable.
Documentation matters: reversing connector orientation may change the intended mapping even when component part numbers are correct. For additional guidance on defining cable assembly drawings and electrical connections, review our cable assembly drawings and pinout requirements.
Made for OEM Equipment Integration
Flat cable selection depends on the actual equipment interface, routing space and operating conditions. Manufacturing follows the approved product construction rather than a universal process for every flat cable type.

Custom Manufacturing Workflow
Engineering Review
Review drawings, samples, connector data and application requirements; establish construction, dimensions and mating interfaces.
Cable Preparation & Assembly
FFC work may include conductor preparation, lamination, contact-end processing, reinforcement and folding. Ribbon work follows its specified cable preparation and IDC or alternative termination route.
Sample Confirmation
Where required, confirm sample dimensions, contact direction, connector fit and electrical requirements before repeat production.
Inspection & Delivery
Complete the specified verification, identification, grouping and packaging based on the approved supply requirements.
Drawing-Based & Sample-Based Projects
A project may start with complete specifications or an existing cable sample. Samples help identify dimensions and construction but cannot establish every material grade, plating or electrical rating without additional evidence. Our sample-based manufacturing guide explains how reference samples and partial documentation can support technical review.

Custom FFC & Ribbon Cable FAQ
Practical questions about cable construction, connector matching, moving applications and OEM manufacturing.
What is the difference between FFC and FPC?
FFC generally uses parallel metallic conductors laminated within insulating films. An FPC is a flexible printed circuit that can contain patterned conductive traces and more complex layouts. They may use similar connector systems but are not automatically electrically or mechanically interchangeable.
Can you manufacture an FFC to match my existing connector?
Yes. A connector part number can help establish contact orientation, cable-end thickness, insertion dimensions and other interface requirements. The opposite-end configuration and finished cable length must also be defined.
Can a folded FFC be used in moving equipment?
A pre-folded FFC is not necessarily suitable for repeated movement. Dynamic applications require a cable construction evaluated for the specified movement path, bend radius and operating conditions.
Can an IDC ribbon cable assembly use different connectors at each end?
Yes, provided the selected cable and connector systems are compatible. The assembly drawing must define each connector's orientation, termination requirements and conductor-to-contact mapping.
Can you reproduce an existing cable from a sample?
Existing samples can be reviewed for cable construction, dimensions and end configuration. Material specifications, exact connector requirements, plating and electrical ratings may require additional documentation or testing rather than visual inspection alone.
