How to repair parallel U disk

The parallel U disk focuses on checking whether the copper plate of the socket part is warped, broken, or rusty, and the circuit is to replace the crystal oscillator (frequency test. You can't fix the memory chip. In addition, use the FAT FAT32 NTFS file format to format separately to see which one can be qualified and easy to use, but it is really not possible to use U-format software formatting, and then use ChipGenius to detect the U disk main control model, and find the corresponding mass production tool mass production repair according to the model.

The U disk is damaged, and a huge part of the U disk can be repaired, of course, the performance will be reduced, for example, 1:2 the U disk is broken, 1 Do the U disk mass production (find the matching mass production tool, provided that the software is damaged).

2 If the hardware is damaged, you need to remove the flash chip and solder it to a good main control board, and then mass production.

Parallel goods and licensed goods are all the same, and they are U disks made by more regular manufacturers, and the difference between Xingshui is that they are fakes, and fakes are U disks made by individuals.

Don't fix it! This is especially true for the storage of important data.

The USB flash drive is flooded, and it can still be used.

Because first, although the USB flash drive is not sealed, it may not completely soak the inside if it comes into contact with water for a short time; Second, even if it is completely wet, the device and PCB will not be damaged at that time.

When the U disk is flooded, the treatment methods and precautions are as follows, to ensure that the U disk is thoroughly dry and completely free of moisture before it can be connected. Secondly, if it is a laundry detergent or other liquid that may cause corrosion to electronic devices, soak it in anhydrous alcohol and then dry it before use.

Do not use the method of exposure to the sun or hair dryer drying, which will bring two harms, one is that it may cause the deformation of the U disk shell; Second, it has a negative impact on the circuit part.

We are now in the daily office, in order to facilitate the preservation of information, we will copy the relevant documents in the U disk, but sometimes when we get home, we forget about it, and as a result, we wash the clothes with the U disk. At this time, many friends are particularly worried that they have important files in the USB flash drive, can they continue to use it after being blistered? What should I do when I use it?

Today, I will talk to you in detail, what should I do if the USB flash drive is washed? <>

First of all, we are sure that even if the USB flash drive is washed with water, it has no effect and can be used normally. Because the USB flash drive itself is not charged, they are essentially a storage base storage device, especially when it is not in contact with the computer or mobile phone, it will not be burned. However, we must remember that after the USB flash drive has been washed with water, it must be carefully handled, sometimes because the structure of the USB flash drive will be more complicated, and the inside will be completely wet, so we must ensure that the USB flash drive is completely dry before it can be used online.

If it is a USB flash drive soaked in water, our treatment method is relatively simple, put the USB flash drive in a ventilated place, let it dry naturally, and it can be used normally in about one to two days. If the potato boy is in a hurry to use it, we can also open the shell of the USB flash drive and dry it carefully with the hot air mode of the hair dryer, so as to ensure that there is no water inside and can be used normally. However, if it is placed in a USB flash drive that has been soaked in laundry detergent or laundry detergent, we must carefully check whether the USB flash drive is damaged.

It is best to use high-purity alcohol to gently wipe the part of the laundry detergent inside the U disk, and then use the above methods to dry it and dry it to be used normally. <>

To sum up, we should deal with the USB flash drive in time after it has been blistered, so that it can be used normally after it is completely dry, remember not to insert it into the computer with water, otherwise it will damage the hardware of the computer, and even cause the computer motherboard to burn out.

The USB flash drive itself is not electrified, so it will not be short-circuited if it falls into the water, and if it can be dehydrated correctly, it will generally not affect the performance and use. Some people will use the hair dryer to forcibly dry the water U disk, although this method is fast, but there are great drawbacks.

Although heating and drying can shorten the dehydration time of the USB flash drive, the damp circuit board base dries quickly due to external heating, and the internal moisture of the USB flash drive cannot volatilize synchronously, at this time, due to the internal stress, the circuit board will crack and the circuit will be damaged, so simple heating and drying is not advisable.

And many people do not do pretreatment before drying the USB flash drive, although the USB flash drive will not occur after falling into the water, but when we use a hair dryer to dry it or dry, as the water evaporates, the salt and other impurities in the water are attached to the circuit board, these things are often electrical conductors, and it is likely to damage the USB flash drive when it is used with electricity.

Correct treatment method: Do not rush to dry the U disk after it falls into the water, rinse it with clean running water first to ensure that there is no sewage in the U disk, and it is best to rinse it with anhydrous alcohol if possible. The sooner this is done, the better.

If the USB flash drive has not been processed in time and has been dried naturally, it is recommended to disassemble it, take out the circuit board and clean the board base with anhydrous alcohol and a soft brush, and then dry the USB flash drive naturally. The performance of the USB flash drive after this treatment will not be affected in general.

Dry the water and find a hair dryer to dry it.

Don't worry, you can blow it with a hair dryer, many USB drives are waterproof, so you can wait and throw the water out,。。 Don't be in a hurry to plug in the computer, it's easy to burn the board of the USB disk... If not, you can take it for repair and change the board. Just more than 20 of them. 、

Dry naturally in a cool place, if you have the conditions and are familiar with the structure, you can disassemble it and dry it with a soft towel, and then connect it to see if it is damaged to decide whether it is sent for repair.

ps, if you are not familiar with it, it is recommended that you send it for repair directly after entering the water.

The tray can still be used even if it is flooded, but it needs to be operated correctly. When you find that the USB flash drive is flooded, do not immediately plug it into the computer and other equipment to power on. Otherwise, the USB flash drive may be scrapped due to short circuit and burn some components.

2.Extended Resources:

The USB flash drive itself is not electrified, and the water is all dried after washing, which does not have much impact. Disassemble the USB flash drive to remove dust. If the USB flash drive is not treated in time after being thrown into the sewage, it has been dried naturally.

It is recommended to disassemble the USB flash drive before using it to avoid short circuit or rust damage to the components after the power is on. Leave the USB stick to dry naturally. Place the USB flash drive in a ventilated place, do not expose it to the sun, and wait for it to dry automatically.

It is emphasized that during the drying process, do not use equipment such as hair dryers to dry quickly. Because although the hot air drying speed is fast, the moisture cannot be volatilized synchronously, resulting in the internal force of the USB flash drive, which may damage the USB flash drive.

1. The U disk is different from the mobile phone, the internal label of the mobile phone will change color after the mobile phone enters the water, and the after-sales personnel will determine whether the mobile phone is damaged by water according to this label, if so, then it cannot be guaranteed. The U disk is a cheap electronic device, and there is no such label, so the after-sales service cannot judge whether the U disk is water.

2. The U disk is not plugged into the computer, and there is no power supply inside, so after the U disk enters the water, as long as it is not plugged into the computer, it will not be damaged, and it can be used after natural drying.

It can be dried, when plugging in may be short-circuited.
