When looking for a custom OEM LVDS (Low Voltage Differential Signaling) cable assembly or LVDS cable manufacturer, it’s important to consider the specific requirements of your application, such as cable length, signal integrity, and connector types. LVDS cables are widely used in applications like high-speed data transmission, video displays, and industrial control systems, making them an essential component for many modern electronics.

Key Considerations for Custom LVDS Cable Assemblies:

1. Signal Integrity: LVDS is often used for high-speed data transmission, so ensuring minimal signal loss, crosstalk, and noise is crucial.
2. Cable Construction:

• Conductor Material: Copper (or silver-plated copper) is typically used for LVDS cables to ensure low resistance and good signal transmission.
• Dielectric Material: PTFE (Teflon) or similar low-loss materials are commonly used to maintain signal quality.
• Shielding: LVDS cables may require shielding (e.g., foil or braided shields) to protect the signal from electromagnetic interference (EMI) and prevent signal degradation.
• Twisted Pairs: LVDS uses twisted-pair conductors for differential signal transmission. Each signal pair should be kept as close together as possible to reduce noise and cross-talk.

1. Connector Type: Custom LVDS cable assemblies can use a variety of connectors, including:

• FPC/FFC Connectors: Flexible flat cables with connectors like ZIF (Zero Insertion Force) or LIF (Low Insertion Force) connectors for compact and reliable connections.
• DF13/DF14: These are commonly used in industrial and consumer applications for LVDS display connections.
• Mating Connectors: Depending on the application, you may need specialized connectors (e.g., MIPI or LVDS LCD connectors).

1. Cable Length & Customization: Custom OEM cables are often required to match specific lengths, pinouts, or features. The cable may need to be molded or have strain relief depending on the environmental conditions (e.g., bending, movement, or high-stress areas).

Steps for Working with an LVDS Cable Manufacturer:

If you’re planning to create a custom OEM LVDS cable assembly, here’s the general process for sourcing from a manufacturer:

1. Define Your Specifications:

• Signal Speed: LVDS is typically used for high-speed data, so make sure to define the desired transmission speed or frequency (e.g., 1.5Gbps, 3Gbps, etc.).
• Cable Type: Specify whether you need a round cable, flat flexible cable (FFC), or ribbon cable (FPC), based on your space and performance needs.
• Connector Details: Determine the type of connectors that will mate with your device. If custom connectors are needed, be sure to specify the exact requirements for pitch, number of pins, and mechanical features.
• Mechanical & Environmental Requirements: Define the operating temperature range, bending radius, flexibility, and any environmental factors (e.g., outdoor, automotive, industrial, etc.) that could impact the design.

2. Find an LVDS Cable Manufacturer:

Look for an LVDS cable manufacturer that specializes in custom cable assemblies and can accommodate your specific requirements. Some companies offer off-the-shelf LVDS cables as well as full customization services.

3. Recommended Manufacturers:

Here are some well-known LVDS cable manufacturers who can provide custom solutions:

• Darlox: Known for a wide range of interconnect solutions, Molex offers custom LVDS cable assemblies tailored to your specific needs. They provide everything from FPC to wire-to-board solutions and support high-speed signal integrity.
• Amphenol: A global leader in connector and cable assembly solutions, Amphenol provides a variety of LVDS cable assemblies for different applications, including displays, automotive systems, and industrial control.
• TE Connectivity: TE offers a wide selection of LVDS cable assemblies and connectors. Their cable assemblies are used in applications ranging from displays and cameras to embedded systems and industrial machinery.
• L-com: L-com is a well-regarded manufacturer of custom cable assemblies, and they can provide LVDS cable assemblies for applications such as video displays, data transmission, and industrial systems.
• Cable Matters: Cable Matters offers off-the-shelf LVDS cables, but they also provide custom cable assembly services for a wide range of signal transmission needs, including LVDS.
• Custom Cable Manufacturers: For more specialized or niche requirements, you can find custom cable manufacturers who provide full design and assembly services. These manufacturers may also help with prototyping, ensuring the cables meet precise electrical, mechanical, and environmental specifications.

4. Engage with the Manufacturer:

• Request a Quote: Reach out to the manufacturer with your custom cable specifications. Include details such as cable length, connectors, shielding requirements, and any other specific needs.
• Provide Detailed Drawings or CAD Files: If available, share any drawings, CAD files, or 3D models to ensure the manufacturer understands the exact dimensions and specifications of your custom cable.
• Prototype & Testing: Most manufacturers will produce a prototype for you to test. It’s important to test signal integrity (e.g., differential voltage levels, signal speed), mechanical durability (bending tests, pull tests), and other performance characteristics in your specific application.

5. Review and Approve the Prototype:

Once the prototype has been developed, conduct testing for both electrical and mechanical parameters. Ensure the cable functions in the intended environment (e.g., data transmission over the required distance without interference). Verify compatibility with the system’s connectors and devices.

6. Production and Lead Time:

Upon approval of the prototype, the manufacturer will move to full-scale production. Lead time can vary depending on the complexity of the cable assembly and any additional features such as custom connectors or overmolding.

7. Quality Control and Compliance:

Ensure that the manufacturer adheres to quality standards, such as ISO 9001, RoHS compliance (for materials), and UL certification if required. It’s also important to check for any other industry-specific standards that your application might require (e.g., automotive, medical, or aerospace).

Conclusion:

Finding a reliable LVDS cable manufacturer for custom assemblies involves understanding your specific needs, working with manufacturers who specialize in high-performance cable solutions, and ensuring the final product meets both electrical and mechanical specifications.
