The mouse is an important external device of the computer and is often used in our work. During the use of the mouse, various problems will occur. For example, if the mouse malfunctions, we need to disassemble the mouse for repair. How do you take apart the mouse? Below we will bring you the detailed disassembly process of the mouse. If you also have questions in this regard, come and see with us how to repair the mouse if it malfunctions.

How to disassemble a mouse

The most common problem with mice is that the buttons fail. When the mouse buttons are not good or insensitive, we need to disassemble and repair the buttons. replace. So how to disassemble the mouse?

Step 1. Prepare the mouse and related tools that need to be disassembled.

Step 2. Here’s how to disassemble the mouse and find the fixing screws (cross-shaped screws) on the mouse, usually 1 to 3, and they are relatively hidden.

Step 3. Use a flat-blade screwdriver to pry open the lower edge of the mouse. And pull the mouse cover back hard.

Step 4. Take out the mouse circuit board. See how the mouse is disassembled. In fact, the structure of the mouse is very simple.

Step 5. Use a soldering iron to remove the components that need to be replaced. The problem of how to disassemble the mouse is solved. Here we take replacing the buttons as an example.

Step 6. When replacing components, be careful not to reverse the direction.

Step 7. Finally, restore the mouse according to the steps of how to disassemble the mouse. The problematic mouse is reborn.

Teach you how to disassemble an optical mouse

How to disassemble an optical mouse? To disassemble the mouse, of course you have to disassemble it from the bottom. Generally, there is only one screw at the bottom of the mouse, and there are also ones without screws that snap directly together - it is not easy to disassemble it. Let us teach you how to disassemble an optical mouse. Unscrew the screws and you can easily take the mouse apart. Like the IBM mouse in my hand, there are two screws at the tail. After being removed, the top cover can be removed.

As for the other one, it was much more troublesome. Even after I unscrewed the tail screw, it still couldn't be opened. After careful consideration, I finally found the key point - there is something underneath the trademark film. Two screws. Most mice do not have such a design. This is quite special. If you want to confirm whether there are screws under the logo, just use a small screwdriver to lightly tap on the logo. The place where the screws are located will be recessed, and then you can The trademark has been torn off.

After removing these two screws, pull the upper cover back slightly, and the front buckle will be easily removed. In this way, the upper cover will be removed perfectly. It is very easy. . Now, the internal structure of the mouse is basically exposed in front of us, it is such a simple thing - but what are the functions of these parts, and what is the working principle of the mouse, we will talk about it in detail later.

The working principle of the optical mouse is: there is a light-emitting diode inside the optical mouse, and the light emitted by the light-emitting diode illuminates the bottom surface of the optical mouse (this is why the mouse The reason why the bottom always glows). Then, a part of the light reflected back from the bottom surface of the photoelectric mouse passes through a set of optical lenses and is transmitted to a light-sensing device (micro-imager) for imaging.

How to disassemble the mouse micro switch

1. First prepare the tools to pry the mouse micro switch. You can flatten the front end of the thin iron wire for later use, and grind it as thin as possible. A little, or use a thin razor blade or bamboo toothpick as a tool to pry open the micro switch.

2. One side of the mouse micro switch is closely connected with other components, and it is not easy to remove it. Usually there is one side of the mouse micro switch that is not blocked by components, so you need to pry from this side first.

3. Observe carefully before disassembling. There are two clips on the micro switch, which firmly lock the micro switch. You must use a toothpick to press the clip of the micro switch inward, and then gently lift it up from the gap at the bottom of the micro switch.

4. When removing the micro switch cover, do not use excessive force. One side of the cover should fall off. Then use a straightened paperclip to remove the micro switch from the side that is detached, and lightly touch the clip on the opposite side to remove the cap.
