With the continuous evolution of electronic devices towards thinness, precision, and high-speed performance, the requirements for internal interconnection systems are also increasing. Traditional ribbon cables or twisted pairs are no longer able to meet the integrity and spatial layout requirements of high-speed signals, and ultra-fine coaxial cables (Micro Coaxial Cable) are gaining popularity due to their excellent performance, becoming the preferred solution for internal connections in high-end products. This article takes the Hirose DF36-30P-0.4SD high-end connector as an example, to help you understand why ultra-fine coaxial cables are expensive and what value they offer.
What is a very fine coaxial cable?
Micro coaxial cable is a high-frequency cable with an extremely small diameter, excellent shielding performance, and stable signal transmission. It is widely used in high-integration electronic devices such as mobile phones, tablets, laptops, cameras, etc., to realize internal transmission of high-speed data, video, or radio frequency signals.
The main advantages of this wire include:
• Extra small outer diameter, flexible wiring in narrow spaces.
Excellent signal integrity, supporting high-speed high-frequency transmission.
• Multilayer shielding structure, effectively resistant to external electromagnetic interference.
These very characteristics make it indispensable in high-performance electronic devices.
Why is it more expensive than ordinary wire?
The high price of ultra-thin coaxial cables is not accidental, but rather determined by the materials, manufacturing, and quality control involved. The main reasons include:
Material cost is high: the core uses high-purity copper conductors and multi-layer shielding layers, which have very high requirements for the performance of insulation and conductors.
The process is complex: micro-level conductor processing, precise welding, and terminal assembly require far higher process levels of production equipment and technical personnel than ordinary cables.
Low yield rate: The size is very small, the manufacturing tolerance is extremely low, and the detection and screening process is time-consuming and labor-intensive.
4. Customization requirements are diverse: Different customers have varying requirements for length, port, wire sequence, and arrangement, often requiring small batch customization production.
These factors combined make the overall cost of extremely fine coaxial cables higher than that of traditional wire materials, but the return on performance and reliability is also significant.
Three, expensive, is it worth it? — From the Hirose DF36-30P-0.4SD to find the answer
In high-end electronic products, signal integrity directly determines the product experience. If ordinary cables are used, problems such as signal packet loss, EMI interference, and shortened lifespan may occur. Extremely thin coaxial cables can effectively avoid these risks and ensure that the equipment remains stable and reliable under high-speed operation. In the extremely thin coaxial cable system, the matching of the connectors is also crucial. Taking the Hirose DF36-30P-0.4SD as an example, this is a micro board-to-board connector optimized for micro coaxial cable, featuring the following characteristics:
Super-fine design with a 0.4mm spacing, saving space.
• 30PIN dual-point structure, improving signal contact stability.
Ultra-low profile design, suitable for ultra-thin devices.
Outstanding seismic resistance and durability, meeting high standards for industrial and consumer applications.
Therefore, in high-performance and high-stability equipment, using ultra-fine coaxial cables with Hirose DF36-30P-0.4SD connectors is a solution that balances reliability and design freedom.
The reason why ultra-fine coaxial cables are expensive lies in their high standards of materials, technology, yield, and customization. However, in the pursuit of high-speed, thin, and stable modern electronic devices, their high signal integrity and long-term reliability are irreplaceable. For high-end products, this investment is worthwhile.
