Generally, when welding the micro USB base, please pay attention to aligning the pins with the wiring points on the solder pad. For the rear position, gently press the pins with a soldering iron and wait for a few seconds to cool down before welding can be completed. However, it is important to remember that when pressing on the pins of the USB motherboard in Luotie, be careful not to squeeze too much, otherwise it may cause the micro USB motherboard interface pins to be soldered through. After practical operation experience, we have come up with a few operational details. Below, we will mention the welding details of the micro USB base.

1. Generally, due to the large number of interface pins on the micro USB motherboard, and the longer the pin pin, the smaller the pressure resistance, do not use heavy objects to compress the product when storing the interface of the USB motherboard to avoid damage to the USB motherboard. Moreover, it is recommended to use tape packaging on the packaging of the micro USB motherboard, as this can avoid pin damage caused by some drops during welding and handling operations.

Secondly, in the welding of the micro USB motherboard, please be careful not to pour out all the packaging tubes of the micro USB motherboard at once. If you do not pay attention to the force when picking up the material, the products will squeeze each other, causing a pin foot to bend under force and show unevenness on the solder pad, leading to the possibility of false soldering during welding.

3. Due to the lack of plastic positioning columns at the bottom of the micro USB base, it is easy to cause position deviation problems due to improper conventional operations, especially in some cases where machine mounting is used. Generally, during welding, please pay more attention to whether the plastic positioning columns of the USB base are welded correctly. Before welding, otherwise once the rear position is welded firmly, it is difficult to modify and adjust the position of the USB base.

4. When manually soldering, it is usually important to place the micro USB motherboard on the solder pad of the PCB circuit board. It has been found that many conventional users may have a deviation in the interface of the micro USB motherboard connector when it comes out of the SMT port. As a result, the 5 pin pins of the USB motherboard cannot correspond to the solder pad, resulting in the hidden danger of no function or short circuit caused by rearranging.

5. Before welding the USB base, it is generally important to apply flux to the solder joints and pins, but remember not to stick too much flux, otherwise it will be difficult to remove in the later stage. 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. In addition, regarding the small size of the USB motherboard, it is generally difficult to solder the pins on the USB interface. If the distance between the pins is too close during critical soldering, accidentally welding the two pins together will occur. Although the use of micro USB sockets is quite common, if one does not have a basic understanding of USB socket usage, some precautions and issues in the use of USB sockets can easily be ignored, which can also lead to the occurrence of faults. However, in the event of a short circuit fault in the micro USB motherboard that cannot be used in daily use, for detecting circuit faults, do not test the circuit while the USB socket is powered on. Moreover, it is generally not recommended to handle it without authorization unless it is a technical personnel, to avoid exacerbating the hidden danger of the fault.
