In electronic devices, internal connectors are responsible for signal transmission and power supply, directly affecting the performance and reliability of the equipment. Especially in high-density connectors such as board to board (B2B) connectors and ribbon connectors, the spacing size plays an important role in signal quality, power consumption, and device structure. With the miniaturization of devices, the application of half pitch connectors is becoming increasingly widespread. Connector manufacturers' popular science: What is the significance of connector spacing design

　　The spacing design of connectors directly affects the performance, reliability, and safety of equipment. The external dimensions of connectors may be similar, but different spacing can result in significant differences between them. This is because as manufacturing becomes increasingly advanced, connectors can be made smaller. Some connectors only carry a small amount of current and voltage, so they can be made smaller to save space and material costs. Sometimes higher conductivity power is required in other projects, requiring connections and wires with higher capacity.

　　The influence of connector spacing on signal transmission

　　Pitch refers to the distance between the centers of adjacent pins, and common specifications include 0.3mm, 0.5mm, 1.0mm, 1.27mm, 2.54mm, etc. Connectors, as an important component of electronic products, are commonly used to connect various circuit boards and devices. In terms of signal transmission, the spacing between connectors has a significant impact on the interference and signal-to-noise ratio of signal transmission. When the spacing between connectors is too small, crosstalk is prone to occur during signal transmission, leading to a decrease in signal quality. When the spacing between connectors is too large, the loss during signal transmission is high, and the poor signal penetration ability affects the transmission effect. Large pitch connectors are suitable for high current applications such as power connectors, while small pitch connectors have higher terminal density and are suitable for lightweight devices, but require optimized heat dissipation and power management. Therefore, a reasonable spacing between connectors can ensure the reliability and stability of signal transmission.

　　In product design, the spacing between connectors also needs to be strictly controlled. For example, when the product size is small and the connector layout is compact, the connector spacing should be minimized as much as possible to ensure that the layout is compact and can meet the requirements of signal transmission; When the product size is large and the connector layout is loose, the connector spacing can be larger to ensure the quality of signal transmission and the reliability of the product.

　　Connector Manufacturer Science Popularization: The Impact of Connector Spacing on Maintenance and Repair

　　Perhaps you would also like to understand another aspect, that the size of connector spacing during product repair and maintenance can also have an impact on firmware upgrades and interface disassembly and assembly operations. The spacing between connectors is too small, which is not conducive to disassembly and maintenance, and can easily damage device interfaces; If the spacing is too large, it is easy to cause weak insertion and removal, which affects the service life of the product.

　　The cutting-edge technologies such as 5G, IoT, and artificial intelligence are flourishing, and the digital transformation of various industries is accelerating. The signal interaction of electronic components in smart driving cars and the demand for stable connections in smart home systems all impose strict requirements on the performance, accuracy, stability, and adaptability of connectors. Based on the actual industry product customer application, the selection of connector manufacturers, and how customers can choose the appropriate connector spacing, the selection reference is as follows:

　　High speed data transmission (PCIe, USB4, MIPI) is recommended to be 0.4mm-0.8mm to reduce signal loss and require shielding design.

　　Smartphones and tablets use 0.3mm-0.5mm to meet the demand for miniaturization.

　　Automotive electronics (ADAS, in car cameras) require 0.5mm-1.27mm to ensure shock and temperature resistance.

　　Industrial equipment and robots are recommended to be 1.27mm or larger to enhance mechanical stability.

　　Select power modules and high-power devices with a thickness of 2.0mm or more to ensure high current supply and current carrying capacity.

　　Overall, when selecting connectors, equipment requirements should be considered comprehensively, balancing signal performance, power consumption, stability, and space limitations. The design of connector spacing is not only a reflection of technical strength, but also a creator of customer value. From smartphones to industrial robots, from new energy vehicles to data centers, every optimization of spacing is driving the electronics industry towards higher performance, reliability, and intelligence.
