The interface pins of the micro USB motherboard are thinner, and the longer the pin pin, the smaller the compression resistance. Therefore, do not use heavy objects to compress the product when storing the interface of the micro USB motherboard to avoid damage to the micro 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 base, please be careful not to pour out all the packaging tubes of the micro USB base 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.

Due to the lack of plastic positioning columns at the bottom of the micro USB motherboard, it is easy to cause positional deviation issues 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 Mike USB motherboard are welded correctly. Before welding, otherwise once the rear position is welded firmly, it is difficult to modify and adjust the position of the Mike USB motherboard.

When manually soldering, it is common for users to place the micro USB motherboard on the PCB board pad. It is 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 pad, resulting in a hidden danger of reactive power or short circuit caused by rearranging.

Before welding the McUSB 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 on. 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.
