Solution for ultra-fine coaxial cable束 for high-speed electronic devices—meets high-density connection requirementsWith the continuous development of laptops, ultra-thin display devices, VR/AR devices, high-speed communication terminals, and intelligent hardware products towards thinness and high-speed, the internal space of devices is becoming increasingly limited. At the same time, higher requirements are put forward for the stability of signal transmission and electromagnetic compatibility (EMC) performance. Traditional cables are prone to external electromagnetic interference during high-speed signal transmission, leading to signal attenuation, increased crosstalk, and even abnormal data transmission. Therefore, ultra-fine coaxial cables with excellent shielding performance are gradually becoming an important solution for internal connections in high-speed devices.
This solution corresponds to the I-PEX 82868-100B-02-D ultra-thin coaxial cable assembly, which adopts a 20PIN, 0.4mm pitch cable end connector structure, and is matched with the connector model 20680-020T-01. It is suitable for high-density, high-speed signal transmission applications. This type of ultra-thin coaxial cable assembly has the characteristics of small size, high flexibility, and excellent signal integrity, and can meet the comprehensive needs of engineers for optimizing spatial layout, high-speed signal transmission, and reliable connection.
How is electromagnetic interference suppressed in extremely thin coaxial beam?——Enhancing EMC performance through structural designFor high-speed electronic devices, electromagnetic interference (EMI) is an important factor affecting signal quality. The key reason why ultra-fine coaxial cables can maintain stable performance in high-speed transmission environments lies in their special coaxial structural design.
Fine coaxial cables are typically composed of a central conductor, an insulating medium layer, a metallic shielding layer, and an outer protective layer. The central conductor is responsible for high-speed signal transmission, the insulating layer is used to maintain stable electrical performance, and the outer metallic shielding layer forms electromagnetic isolation protection. When there is electromagnetic noise externally, the shielding layer can effectively block interference signals from entering the transmission path; at the same time, the electromagnetic radiation generated by the internal high-speed signals will also be confined within the shielding layer, thereby reducing the impact on surrounding electronic components.
In practical applications, the suppression of electromagnetic interference by extremely fine coaxial cable束 is achieved in the following ways: Firstly, a complete and continuous metal shielding structure is adopted to improve the anti-interference capability of the signal channel; secondly, by reasonably controlling the grounding method of the shielding layer, the grounding impedance is reduced, and common-mode noise is reduced; at the same time, by accurately controlling the structural dimensions of the cable, the impedance during signal transmission is maintained stable, reducing high-speed signal reflections and crosstalk.
For the I-PEX CABLINE®-CA II series 20PIN ultra-fine coaxial cable assembly, its 0.4mm pitch high-density connection design combined with shielding structure can effectively meet the requirements of EMI control and signal integrity for high-speed display, data transmission, and other applications.
Impedance Matching and EMI Control Focused on by Engineers—Ensuring Integrity of High-Speed Signal TransmissionIn high-speed signal applications, electromagnetic interference suppression relies not only on shield layer design but also on the overall electrical parameter control of extremely fine coaxial cables. Among them, characteristic impedance stability is a key factor in engineering design.
The characteristic impedance of extremely fine coaxial cable束 is mainly determined by the conductor diameter, dielectric constant of the insulating material, thickness of the insulating layer, and structure of the shielding layer. When high-speed signals pass through the cable束, if the impedance changes significantly, it will cause signal reflection, increase eye diagram jitter, and affect the performance of high-speed interfaces. Therefore, in the manufacturing process of professional extremely fine coaxial cable束, it is necessary to precisely control the core wire size, proportion of insulating material, coverage of the shielding layer, and processing consistency to maintain a stable impedance of the entire cable束.
