Custom Flat Ribbon Cable Assemblies

Y.C. Cable manufactures custom flat ribbon cable assemblies for OEM electronics, industrial equipment, computer systems, control equipment, and other applications requiring organized parallel conductor routing.

Assemblies are manufactured according to customer-approved drawings, BOMs, conductor count, pitch, wire specifications, connector requirements, pinouts, cable lengths, fold or routing requirements, and testing criteria.

Flat ribbon cable assemblies are commonly selected when a product design requires multiple conductors arranged in a compact, organized configuration.

Flat Ribbon Cable Configurations

Projects may include:

• Flat ribbon cable assemblies
• IDC cable assemblies
• Board-to-board connections
• Board-to-wire connections
• Connector-to-connector assemblies
• Internal equipment cables
• Multi-conductor interconnects
• D-sub terminated ribbon cables
• Customer-specific flat cable assemblies

Conductor Count, Pitch & Cable Requirements

Important project inputs may include:

• Number of conductors
• Conductor pitch
• Wire gauge
• Conductor material
• Insulation type
• Cable width
• Cable length
• Cable color
• Pin-1 identification
• Polarity requirements
• Electrical requirements

The cable specification should follow the approved equipment design and connector system.

Connector & Termination Options

Flat ribbon cable assemblies may use customer-approved:

• IDC connectors
• Board connectors
• D-sub connectors
• Socket connectors
• Header-related connector systems
• Crimp-style terminations
• Customer-specified connectors

Project documentation should identify:

• Connector manufacturer
• Connector part number
• Contact count
• Connector orientation
• Pinout
• Keying or polarization
• Strain-relief requirements

Routing, Folding & Installation

One of the key design considerations for flat ribbon cable is how the assembly will route inside the finished equipment.

Requirements may include:

• Overall length
• Fold locations
• Fold direction
• Connector orientation
• Routing path
• Available installation space
• Bend requirements
• Strain relief
• Mounting points
• Service access

Fold locations and connector orientation should be shown clearly on the approved drawing when they affect installation.

Electrical Requirements

Electrical requirements may include:

• Voltage
• Current
• Signal type
• Pin assignment
• Grounding
• Conductor spacing
• Crosstalk limitations when applicable
• Shielding when applicable
• Continuity testing
• Customer-defined signal requirements

Flat ribbon construction alone does not guarantee high-speed data or low-crosstalk performance. Those requirements should be defined by the complete cable and system specification.

Identification & Polarization

To reduce assembly and installation ambiguity, projects may define:

• Pin-1 marking
• Cable edge marking
• Connector keying
• Polarized connectors
• Labels
• Part-number identification
• Orientation markings

These requirements should be included in the drawing or BOM.

Frequently Asked Questions

What is a flat ribbon cable assembly?

A flat ribbon cable assembly uses multiple parallel conductors arranged in a flat configuration and terminated according to a defined connector, pinout, length, and equipment requirement.

Can Y.C. Cable manufacture IDC ribbon cable assemblies?

Yes, when the cable, IDC connector, conductor count, pitch, pinout, and manufacturing requirements are defined in the approved product documentation.

Can ribbon cables be made with custom folds?

Yes. Fold locations and orientation can be manufactured according to customer-approved drawings when compatible with the specified cable construction.

Can flat ribbon cable assemblies include D-sub connectors?

Yes, when the applicable connector, cable, pinout, and termination requirements are specified by the customer.

Can you support prototype ribbon cable assemblies?

Yes. Prototype and first-article builds can support fit, routing, connector orientation, and electrical evaluation before repeat production.
