The world of electronics manufacturing is fiercely competitive, with OEMs seeking every opportunity to differentiate themselves, shorten time to market, and deliver products that perform reliably over many years. When it comes to high-speed data transmission, many OEMs are straying away from the use of standard, off-the-shelf LVDS cables in favor of custom-made assemblies. The reasons for this include electrical optimization, mechanical fit, control over the supply chain and Total Cost of Ownership or TCO.
Every electronic product has unique mechanical constraints and integration requirements. For example, the printed circuit boards are located differently. Connector orientations and cable routing paths vary depending on internal mechanical layouts, navigating around components, through hinges, and along the sides of the chassis. Standard off-the-shelf cable assemblies available through distributors often cannot provide customized lengths, connector orientations, or jacket materials.
Custom LVDS cable assemblies were developed to address these challenges. OEMs are able to specify exact cable lengths, connector type and orientations, required bend radius values and specific jacketing materials. Custom cable assemblies can be pre-formed in order to adhere to desired cable routes which significantly reduces the assembly time as well as removing the need for manual cable management. Hotten develops cable assemblies engineered around each customer's mechanical and electrical requirements, eliminating the limitations of standard cable solutions. In applications such as AR/R devices, drones, gimbals, and medical equipment. it is often important that cables fit without adding unnecessary weight to weight-sensitive applications that could affect overall operation.
It is often the case that standard LVDS cable assemblies are built for a number of general purpose applications, and do not fit the unique needs of every high-speed interface. Different data rates, transmission requirements, and EMI environments require carefully optimized cable performance characteristics. Maintaining precise impedance control often requires manufacturing tolerances beyond what standard cable assemblies can achieve.
OEMs are able to precisely control the electrical characteristics of their cable assemblies as follows:
Precise differential impedance (e.g., 100Ω ± 5% instead of ±10%) reduces signal reflection, resulting in a clearer signal.
Skew is held to a minimum between differential pairs in order to enhance the timing margin.
Advanced shielding strategies may be designed specifically for high-noise environments common in medical and industrial applications to protect signal integrity.
Bespoke attenuation targets can be achieved over longer cable lengths when designing for a defined application.
Hotten works closely with OEM engineers to determine optimal LVDS cable specifications for unique system requirements, whether for high-resolution medical display or high-speed robotics. Standard off-the-shelf cables often cannot promise or provide the signal integrity required for modern electronics.
A standard off-the-shelf cable may need to be cut to length, bundled, and secured with tie wraps, all of which adds to the overall assembly time and increases costs through labor. Cables that are not keyed correctly can lead to being improperly connected. Jacketing that is too rigid can make routings slower, delaying assembly lines.
A custom-made cable assembly comes to the OEM ready to install. Specific lengths remove unnecessary cable management, which reduces assembly time and errors, while custom-made connector housings often include keying features to make correct connections more intuitive and easier. Strain reliefs, overmolding, and color-coding jacket material further simplify assembly and lead to a lower total installed cost, even if the initial unit price is greater than a standard alternative cable assembly. OEMs who have purchased custom-made LVDS cables from Hotten have frequently seen their assembly times reduce as well as yields increase significantly.
Companies that rely on standard LVDS cables from a third party distributor are exposed to inherent risks associated with the supply chain. A cable might be discontinued, a supplier's component quality may become inconsistent, or lead times could become erratic.
Direct sourcing from an LVDS cable manufacturer such as Hotten allows OEMs more control over their supply chain. They are able to document exact specifications and gain consensus on any changes in the cable specification before they take place. OEMs can also negotiate realistic lead times based on production plans, a factor that is especially critical for high volume products with longer lifespans, such as medical devices or complex industrial machinery.
In a marketplace flooded with product offerings, companies have limited opportunities to differentiate their products through internal components. A custom-made cable can offer just this, with custom jacket color options, a logo laser etched on the cable itself, uniquely molded connector housings, and overall product consistency throughout the product line.
Even when components are invisible to the end-user, these types of details contribute to a professional, high quality product. This detail often builds the customer's confidence in the product they have purchased and improves the perception of brand quality and reliability. For consumer electronics, a well-engineered internal design enhances the overall user experience — even when cables are hidden inside. In the medical market, visual quality impresses clinicians who work with the device's cabling daily.
For many OEMs, developing in-house expertise for custom cable assemblies can be challenging. In order to design a custom cable that meets specified requirements, a high degree of technical expertise is needed, ranging from impedance matching to knowledge of dielectric materials, shield construction methods, flex testing, and all regulatory considerations. Developing custom LVDS cables without this expertise may result in product reliability issues, delayed launches, or costly redesigns.
Partnering with a specialized cable manufacturer, like Hotten, ensures access to expert knowledge of the electronics market. Our engineers develop over 300 custom cable specifications annually, and can provide assistance through all stages of product development from specifying electrical performance to ensuring physical constraints are met and finally to the testing process itself. This close partnership reduces the risk to an OEM and speeds up the design cycle considerably.
A growing number of OEMs are choosing custom LVDS cable assemblies over off-the-shelf products because of the many benefits that a custom solution provides. Those benefits range from precise mechanical fit and optimal electrical performance to reducing assembly time and installed costs, improved reliability, maintained control over supply chains, brand differentiation, and the significant availability of design and R&D support from your manufacturing partner. The design engineers at Hotten make full use of their high levels of engineering ability, innovative R&D techniques and manufacturing precision to offer custom LVDS wire harnesses that provide real, significant competitive advantages to OEMs. Whether for complex medical systems or cutting-edge consumer electronics, the right solution requires the top performance and reliability needed in a custom cable assembly. Use Hotten for your next custom LVDS project.
