1. What is the historical process of the development of ultra-thin coaxial connectors and ultra-thin coaxial connectors, as well as the present and future of ultra-thin coaxial connectors: What is ultra-thin coaxial connectors? The ultra-thin coaxial line connector is mainly used to connect digital signals between module boards in the differential transmission mode through the ultra-thin coaxial line. For proper signal transmission, the central conductor that transmits the signal needs to be connected to the signal circuit on the PCB board through the terminals of the connector. The outer conductor of the cable needs to be electrically connected to the PCB board through the metal part of the connector-the housing. The electrical connection of the outer conductor to the PCB board through the connector housing is called "ground". History of Extremely Thin Coaxial Connectors Extremely thin coaxial lines have an outer conductor that provides electromagnetic shielding, making electrical signals transmitted through the central conductor less susceptible to external electromagnetic waves (or electromagnetic noise). This gives the cable a high degree of flexibility and high shielding performance. To realize these advantages, it is necessary to process and terminate these small cables one by one, so that the very thin coaxial lines can be used as jumper connections for digital signals. In the past, because it was difficult to produce cables with stable quality, ultra-thin coaxial lines were only used in a few equipment such as expensive medical equipment, and were not widely used in general consumer electronics products. Notebook computers, which have been widely used since 1990s, are equipped with color LCD screens, with higher image quality and faster display transmission speed. Therefore, when the display is turned on and off, the extremely thin coaxial wire becomes a flexible connection mode while providing high-speed transmission performance, and thus it begins to attract people's attention. I-PEX pioneered the development of a connector that can efficiently and stably connect micro-coaxial cables, while creating the technology to connect these small-sized cables to connectors. In 1996, I-PEX announced the world's extremely thin coaxial connector "CABLINE ® I" for differential transmission of digital signals. Therefore, it is adopted on consumer notebook computers as a digital signal jumper connection using extremely thin coaxial connectors. Today and the future of extremely thin coaxial connectors. With the development of high-speed Internet and the increasing usage of mass storage devices, high-resolution images and videos can be more easily shared on consumer products such as PCs, tablets and smartphones. The amount of information that needs to be processed on these devices increases dramatically, and the signal speed of the devices becomes faster and faster. When electromagnetic noise is added to the outside of electronic equipment, unexpected electrical signals may be generated to the internal circuits of the equipment, causing failure or damage to high-performance electronic components, and may also cause damage to electronic equipment. As the next generation panel connector for CABLINE ®-VS, I-PEX is also developing some EMC shielded connectors (ZenShield ®) to meet various applications and design conditions. The ZenShield ® connector provides board designers with greater flexibility by allowing the connector to be close to sensitive subsystems, such as transmit/receive antennas, which are common in high-performance wireless communication systems. As the data rate increases, the server uses more cable assemblies. These cable assemblies need to minimize their size so that the server system can be easily assembled, while there is unobstructed air flow to ensure heat dissipation. Flexibility is good for high and low speed internal cables, as well as small size, low height. Extremely thin coaxial cables with I-PEX CABLINE ® Series connectors allow for higher density interconnections, reducing system space for cabling and cable assembly terminations.

2. How to choose an extremely thin coaxial connector? ：

Have you ever been confused about how to choose an extremely thin coaxial connector for high-speed transmission? ---There are many factors that can make choosing a connector difficult. To help you make a choice easier, this article provides some examples to illustrate how you should choose the connector that best suits your current application.

Have you ever encountered the following question, "I want to choose an extremely thin coaxial connector, but how do I make my decision"? The decision you make can have a profound impact because the connector is a very important electronic component that will directly affect the performance of the device. If you select the wrong connector, it may cause you to fail to achieve the target performance.

So, is there a better way to choose an extremely thin coaxial connector? If you follow the steps below, the selection process can go relatively smoothly.

---------------------------------------------------------------------------------------------------

① Clarify transmission standards

Different devices and components follow different transmission standards. Before selecting a connector, select the signal you want to transmit. The transmission speed is determined by the transmission standard. ② EMC mitigation measures What is electromagnetic compatibility (EMC)? When a signal is transmitted, it emits noise to the ambient environment (EMI) while being affected by ambient noise (EMS). This noise generated by the signal can adversely affect the performance of the peripheral device. Similarly, when ambient noise interferes with a signal, its transmission is adversely affected.

I-PEX's ZenShield ® technology helps prevent ambient noise from affecting the signal in the connector and prevents noise generated by the signal from affecting external components. This shielding technology gives you more freedom when placing other electronic components and helps to achieve high-density mounting, which is the trend for board mounting.

If you are struggling with noise, here is an example of an EMC shield (ZenShield ®).

③ Necessary number of pins The next step is to select the number of pins required for the application. Choosing a large pin count requires a larger connector, which takes up more space on the PCB. It also adds to the cost. ④ Description of connector size The connector size is expressed in height direction, pitch arrangement direction and depth direction. Among them, the most common limitations are height and pitch dimensions

Why is the larger fit size of the connector important? The extremely thin coaxial connector female socket is mounted on the PCB and then fitted to the male socket harness. If the fitting height is too high, it may interfere with the device enclosure and prevent the enclosure from being installed as planned. What is spacing? Spacing refers to the distance from the center of one terminal pin to the center of the next terminal pin. Why is spacing important? For extremely thin coaxial connectors, the spacing of the connectors limits the larger outer diameter of the cable that can be used.

(Example 1: 0.5 mm pitch 10 pin connector, compatible cable outer diameter larger than 0.5 mm).

(Example 2: 0.4 mm pitch 10 pin connector, compatible cable outer diameter larger than 0.4 mm).

The larger the cable diameter, the lower the loss, resulting in better transmission performance. However, a larger cable diameter also takes up more space, resulting in a thicker harness. ⑤ Determine the cable size What is AWG (American Wire Gauge)? As shown in the figure below, AWG is a number represented by the center conductor diameter. The larger the AWG number, the smaller the diameter.

(Image of an extremely thin coaxial cable structure) Imagine a water passing through a pipe. The wider the pipe, the more water flows through it. The same applies to cables. The larger the diameter of the center conductor, the more current flows through it. Conventional wisdom is that you should always use thicker cables. However, as mentioned earlier, the size of the cable used with the connector is also limited by the spacing of the connector.

3. Why can I-PEX's ultra-thin coaxial connectors be widely used? : 1) Features of I-PEX ultra-thin coaxial connectors I-PEX Connectors is a pioneer in the ultra-thin coaxial connector industry, providing coaxial connector products suitable for many different applications. I-PEX ultra-thin coaxial connector ranks among the best in the market share of PC flat connector industry. (CABLINE ®-VS female: VESA standard connector)

2) Characteristics of I-PEX shielded connectors As electronic equipment develops towards high performance, power saving, and miniaturization, the demand for high-speed signals is increasing day by day. The number of electronic components operating at low voltage is increasing, and the installed electronic components The density of components is also getting higher and higher. If electromagnetic noise is added from the outside, it may cause unnecessary current to be generated in the internal circuit of the device, causing the failure or damage of high-performance electronic components, and may also cause the damage of electronic devices. In addition, in electronic devices with wireless communication functions (such as laptops, tablets, and mobile phones), electromagnetic waves generated inside the devices can increase the noise of the wireless communication circuit, thereby reducing the reception performance of the antenna. In this case, in general, the measure against electromagnetic noise inside the device is to physically shield the electromagnetic noise by incorporating the electromagnetic noise filter element into the circuit and/or adding a metal shield to the element. With the introduction of small devices with high-density components installed, and the appearance of high-speed signals in these devices, measures must be taken against electromagnetic noise at the device jumps. I-PEX has developed a connector series that solves the problem of electromagnetic noise in connectors, with suitable grounding structure and covering, including the mounting location of the signal terminal tail with metal shielding (ZenShield ®). This solution is widely used by many customers to prevent electromagnetic interference, especially on high-performance devices equipped with wireless communication functions such as Wi-Fi ®, GPS, and LTE.
