The appearance of the Micro USB waterproof motherboard with a 180 degree vertical insertion data high-definition interface for the MICRO+USB waterproof AB port well adapted to the miniaturization trend of digital electronic devices at that time. The micro USB motherboard is currently the most widely used USB interface on mobile devices (such as mobile phones), and its volume is less than half of the MINI mini USB motherboard interface, making it difficult for a simple tester to match it with the circuit board! The emergence of microUSB motherboards was developed due to the industry's demand for micro device interfaces

Before welding the micro USB waterproof base, it is generally important to use flux to wipe the solder joints and pins, but remember not to stick too much flux, otherwise it will be difficult to wipe off later. Because the function of flux is not only to make welding smoother, but also to fix the USB port and prevent it from shifting during welding. There is also a concern about the small size of the USB motherboard, which is generally difficult to solder on the USB interface pins. If the distance between the pins is too close during critical soldering, accidentally welding the two pins together will occur. After considering these issues when welding, many problems can be easily solved. Designers are easy to draw a board and do not need to consider too many other electronic components arranged tightly. The USB motherboard B-type is a USB interface that we often see on printers. Its interface surface is a square interface, which has high recognition and is a unified standard for printer interfaces. The Mini Mini USB motherboard interface is an improved version of the regular USB motherboard A-type interface, with a volume less than half that of the A-type USB motherboard. The appearance of this Micro USB waterproof motherboard well adapted to the miniaturization trend of digital electronic devices at that time. The Micro Mike USB motherboard is currently the most widely used USB interface on mobile devices (such as mobile phones), with a volume less than half that of the MINI Mini USB motherboard interface, So simple that it is difficult to match it with the circuit board! The emergence of microUSB motherboards was developed due to the industry's demand for micro device interfaces. The latest USB motherboard C-type is the latest USB motherboard standard. For example, the latest 12 inch Apple laptops are equipped with a USB motherboard C-type interface, also known as the USB3.1 interface! The above is only for distinguishing and distinguishing the types of USB interfaces. For example, in terms of packaging specifications, each micro waterproof USB motherboard has a variety of circuit board packaging specifications,
