Let me briefly analyze the detailed explanation of pin welding for the 10P definition of the MICRO USB 3.0 motherboard. Because USB 3.0 includes USB 2.0 pins, USB 3.1 and 3.0 pins are the same, this article uses MICRO USB 3.0 (i.e. USB3.1 Gen1) as an example to explain. First, the first four, that is, the Backward compatibility USB 2.0 part. Because USB 2.0 transmits half duplex differential signals, data transmission requires at least 3 wires - D+/D -/ground wire (two data wires are shared for both uplink and downlink), plus a red wire powered by the positive pole, resulting in a total of 4 wires. Therefore, two pairs of data wires and a shielded ground wire are required. It can be seen that MICRO 3.0 is Backward compatibility, which completely reserves the part of MICRO USB 3.0. In addition, 10 lines are added for full duplex high-speed transmission, which can be understood as doubling the transmission speed. Although the cost is high, the impact of wire quality problems is avoided to some extent.

But at present, there is a trend of USB 3.1 motherboard TYPE-C replacing it, which makes us cannot help but marvel at the rapid development of the digital electronics field. In fact, before the birth of USB 3.1 motherboard TYPE-C, there was a transitional product, which was the gradually forgotten MICRO USB 3.0 motherboard. The reason why it is called a transitional product is because it has never become the mainstream connector interface for mobile device terminals, In fact, the appearance of the MICRO USB 3.0 motherboard was really "born at a wrong time". At that time, the speed of the MICRO USB 3.0 motherboard was the next generation level, but because its speed was too fast, and other hardware levels did not keep up with its rhythm at all, it seemed to have a Déjà vu of "killing chicken without using a knife" at that time. Secondly, its size was too large. Compared with the 2.0 model, it was simply unacceptable, The volume is almost the simple geometric accumulation of two MICRO USB 2.0 female seats, and its interface is strictly differentiated from the corresponding direction for the male head. The product experience is not satisfactory, followed by its high price. The inability to popularize and mass produce determines that its product cost cannot be reduced, which in turn makes manufacturers unwilling to adopt new interface solutions. With the strong launch of USB 3.1 motherboard TYPE-C, its size is similar to that of MICRO USB motherboard, with high-speed transmission and support for forward and backward blind insertion.

USB 3.1 mother seat specifications and styles are applied in many fields: mobile phones, computers, Bluetooth headsets, Bluetooth speakers, mobile power, Electronic cigarette, Selfie stick, wireless charging, tablet computers, electric beard knives, Electric toothbrush, electric beauty devices, children's learning machines and other digital electronic products. We have officially solved the global problem of "USB can never be plugged in or out", with both sides being freely plugged in and out. At the same time, the USB-C male interface used in conjunction with it must also be thinner and lighter.
