Backplane Connectors - Specialized refers to backplane connectors designed and produced to meet the needs of specific industries or applications. These connectors are carefully optimized in terms of structure, materials, electrical properties, etc., to ensure the best performance in a specific working environment. They not only inherit the basic functions of traditional backplane connectors, such as connecting circuit boards, transmitting signals and currents, but also put forward higher customization requirements for specific application scenarios, such as high temperature resistance, corrosion resistance, electromagnetic interference resistance, etc.

Backplane Connectors - Specialized applications are broad and diverse, mainly covering industries with high requirements for electrical connection performance. First of all, in the aerospace field, backplane connectors - dedicated are widely used in the electrical systems of aircraft, satellites and other equipment to ensure the reliability and stability of electrical connections in harsh environments such as extreme temperatures, high vibration and strong electromagnetic radiation. Secondly, in the field of military defense, such connectors also play an important role in providing stable and reliable electrical connections for weapons and equipment and command and control systems. In addition, backplane connector - dedicated is also widely used in industrial automation, medical equipment, high-speed railway, Marine engineering and other fields.

• 1. The main function of the backplane connector?

  Connect the single board (daughter card) and the backplane, the single board and the backplane form a 90-degree vertical structure, transmit high-speed differential signals (differentencial signals) or single-ended signals (single end signals) and transmit large currents.

• 2. Application of backplane connectors?

  Backplane connectors are a key component that is widely used in large-scale communication equipment, ultra-high-performance servers and supercomputers, industrial computers, and high-end storage devices. Its main function is to connect the single board (daughter card) and the backplane, realize the 90-degree vertical structure between the single board and the backplane, transmit high-speed differential signals or single-ended signals, and transmit large currents. This connection method is not only suitable for the field of data exchange, such as inside the switch, but also with the development of technology, it has now become the core application scenario of AI servers, almost all of which use backplane connectors for connection, replacing traditional optical modules.
  
  The application of backplane connectors is not limited to the above-mentioned devices. It also plays an important role in wireless communication, the connection between computer motherboards and various peripheral devices, allowing users to increase or decrease the input and output functions of the system by plugging and unplugging devices, including USB interfaces, audio interfaces, network ports, etc. This connector is generally located on the back of the computer chassis, hence the name.
  
  With the advancement of technology, the importance of backplane connectors in AI servers and high-speed network equipment has become increasingly prominent. In particular, the NVLink technology launched by NVIDIA has demonstrated a trend of high integration by integrating multiple PCC boards into one PCB board, further promoting the improvement of network performance. This requires the design of connectors to improve data transmission efficiency, reduce costs and signal density, despite challenges such as transmission distance limitations.

• 3. Advantages of backplane connectors?

  The advantages of backplane connectors mainly include improving signal quality and anti-interference ability, easy expansion and upgrade, high contact density, fast signal transmission rate, ensuring signal transmission accuracy, long service life, and convenient installation. ‌
