Why is the USB flash drive hot?

It is normal for the USB flash drive to heat up. The inside of the USB flash drive is composed of many electronic components. It needs to be powered through the USB socket on the computer chassis and read by the system. before it can be used. The time you use the USB flash drive varies, and the electronic components inside it will gradually heat up as the USB flash drive runs longer.

But when the USB flash drive is inserted, it starts to get hot. It can be seen that the USB flash drive is faulty. Common causes of failure include the following:

1. The voltage of the USB port of the device connected to the USB flash drive is too high, causing the main control chip on the USB flash drive circuit board to burn out. So the USB drive will be very hot.

2. The USB flash drive has been soaked in water during use, and the circuit board has become rusty, causing a short circuit on the PCB board, so the USB flash drive will be very hot.

3. In daily use, the USB flash drive is mixed with metal shavings, causing the circuit on the PCB to short-circuit, so the USB flash drive will be very hot.

4. The quality of the USB flash drive is not very good. In daily use, the flash memory chip soldered on the PCB has a physical failure and is short-circuited internally, so the USB flash drive will be very hot.

For the above faults, you can try the following solutions:

1. The USB disk is within the warranty period. You can contact the dealer or after-sales service center to solve it.

2. If the USB flash drive has exceeded the warranty period or has lost its warranty qualification, you can try to disassemble the USB flash drive and repair the USB flash drive according to the actual situation (replace the fuse resistor and voltage stabilizing chip on the PCB, Replace the flash memory chip and replace the entire USB main control board).

3. I cannot repair the black colloidal USB flash drive. It is recommended to give up the repair and buy a new USB flash drive.

U disk, the full name is USB flash disk, the English name is "USB flash disk". It is a miniature high-capacity mobile storage product that uses a USB interface and does not require a physical drive. It is connected to the computer through the USB interface to achieve plug-and-play.

The name U disk originally came from a new type of storage device produced by Netac Technology, called "U disk", which is connected using a USB interface. After the U disk is connected to the USB interface of the computer, the data in the U disk can be exchanged with the computer. Since Netac has registered patents for equipment with similar technology produced later, it can no longer be called "U disk" and is renamed the homophonic "U disk".

Later, the name U disk became widely known because it was simple and easy to remember, and it was one of the mobile storage devices. Now there are many USB flash drives on the market that support multiple ports, namely three-way USB flash drives (USB computer port, iOS Apple interface, Android interface)
