What precautions are easily overlooked when using MINI USB connectors

Generally speaking, in the operation and welding of the MINI USB connector seat, please pay attention to each pin aligning with each wiring point on the pad. The back should be pressed lightly with a soldering iron, and it can be welded after cooling for a few seconds. But remember: if the soldering iron presses the pin of the USB female seat, be careful not to squeeze too much, otherwise it will weld the pin of its MINI USB connector interface. Then, through practical operation experience, we can draw several operation details. The following are the details that cannot be ignored in the welding of the MINI USB connector.

MINI USB CONNECTOR

1. Generally speaking, since the MINI USB connector has more interface pins, the longer the pin, the lower the pressure resistance. Therefore, do not use some heavy objects to squeeze the product when storing the interface of the USB female socket to avoid damage to the pins caused by the USB interface. In addition, it is recommended to pack the MINI USB connector on the packaging, as this can avoid pin damage caused by falling during welding and placement operations.

2. Secondly, in the welding of the MINI USB connector, please be careful not to suddenly pour out all the packaging tubes of the MINI USB connector, do not pay attention to the strength of the material, the products squeeze each other, causing individual pins to bend, the pads to be uneven, and the possibility of false welding.

3. Since there is no plastic positioning column at the bottom of the MINI USB connector, it is easy to cause position deviation in some traditional operations, especially in some machine installations. Generally, during welding, please pay more attention to whether the plastic positioning column of the USB interface is correct before welding, otherwise it will be difficult to change the position of the USB interface once the welding is stable.

4. When manually soldering, pay attention to placing the MINI USB connector on the pad of the PCB circuit board. It is understood that many users place the disk, which will cause the entire interface to deviate when the MINI USB connector interface comes out of the patch port, so the five pins of the MINI USB connector cannot correspond to the pad, so the rear placement will cause the hidden danger of no function or short circuit.

5. Before soldering the MINI USB connector, generally pay attention to wiping the solder joint pins with flux, but remember not to stick too much flux, otherwise it will be difficult to wipe it later. Because the effect of flux not only makes the soldering smoother, but also fixes the MINI USB connector when soldering, it is not easy to shift. At the rear, the MINI USB connector is small in size, and the MINI USB connector pins are generally difficult to solder. If the distance between the pins is too close, the two pins will be accidentally soldered together.

The use of MINI USB connectors is very common, but if you do not understand the basic precautions for using MINI USB connectors, some precautions when using MINI USB connectors can easily be overlooked, resulting in failures. However, when the MINI USB connector cannot be used due to a daily short circuit failure, do not detect line faults when the MINI USB connector is powered on. If you are not a technician, it is generally not recommended to handle it privately to avoid exacerbating hidden dangers.
