New choice for ultra-thin laptop internal wiring: ultra-fine coaxial cable bundle solution analysis

Under the trend of ultra-thin laptops continuously developing towards lightweight, narrow bezels, and high performance, the difficulty of internal wiring is increasing. Traditional ribbon cables are difficult to meet the comprehensive requirements of high-speed transmission, strong shielding, and high flexibility at the same time, while micro coaxial cable (micro coaxial cable) has gradually become the mainstream internal interconnection solution for ultra-thin laptops due to its miniaturized structure and excellent electrical characteristics.

Challenge of wiring under thin and light structure

The internal space of ultra-thin notebooks is extremely compact, and there is no extra space between components such as the motherboard, screen, touch module, and battery. Traditional wiring has limitations in terms of bendability, shielding performance, and layout flexibility. The extremely fine coaxial cable束 with a diameter of only 0.2mm to 0.5mm can still achieve flexible wiring in narrow gaps, and at the same time, the coaxial structure ensures that the signal quality is not affected by space compression, making it a key solution for slimming-down designs.

High-speed signal transmission requirements for structure

As notebooks increasingly use high-speed transmission interfaces such as MIPI, eDP, and USB4, the transmission rate generally reaches several Gbps, posing higher requirements for signal integrity. The micro coaxial cable internally uses a design with independent conductors and a shielding layer, which can effectively reduce crosstalk and external electromagnetic interference, enabling high-resolution displays and high-speed data interfaces to maintain stable performance in slim and lightweight bodies.

Three, Bend Resistance and Reliability Design

The hinge area of a laptop is the most prone to fatigue damage of cables, needing to withstand tens of thousands of opening and closing bends. The extremely thin coaxial cable bundle has a flexible sheath structure and a high-density woven shield, maintaining stable electrical performance without sacrificing durability. This prevents signal attenuation, poor contact, or conductor breakage due to repeated bending, thereby enhancing the overall product lifespan and user experience.

In ultra-thin laptops, ultra-fine coaxial cable束 not only improves the quality of high-speed signal transmission but also effectively solves multiple design challenges such as space constraints, high shielding requirements, and high bending at hinge areas, becoming a key wiring solution for structural lightweighting and performance enhancement. As laptop products continuously evolve towards being lighter, thinner, and faster, micro coaxial cable will continue to become the industry standard.
