The membrane keyboard really only has one membrane~~~ It’s time to change to a mechanical keyboard for fun

I was supposed to supervise the little girl at home to type English at night, but the little girl froze and spilled a glass of water on the keyboard with a shake of her little hand, eh~~~ What a lazy donkey~~~ I hurriedly wiped my keyboard vigorously, and suddenly found that the direction key Can't play it.

I don't know which nerve is pressed

There was no other way, so I had to take the keyboard apart to take a look at the water.

so many screws

Unexpectedly, there are so many screws behind the keyboard, which have to be unscrewed manually, and the hands must not be twisted. Please invite the king of household 12v electric drills. The electric drill boss with free shipping within 30 yuan.

There are also multi-purpose bits for a perfect fit.

Small batch, big effect

A screwdriver and multiple bits can be easily used on an electric drill to remove various screws. Reduced a lot of work pressure.

The small keypad has more than 20 screws

If there is no electric tool, removing so many screws by hand will hurt your hands, so you still need an electric screwdriver at home for emergencies.

found the reason

After opening it, I found the reason. It turned out that the small plastic caps on the keyboard fell out, so they couldn't be played. The keycaps rely on the elasticity of these plastic caps to bounce back and type repeatedly. They are really not easy.

The core membrane of the keyboard

The entire film is the core of the keyboard, and the same as the constellation diagram on it is the connection of the keyboard. Not hitting the keyboard once is just a small dot where the keycap is pressed and the lines converge.

black chip

Unexpectedly, there is no hard connection between the keyboard membrane and the chip, and a laminated connection is also used.

Just rely on a strip to hold it down

Such a simple contact structure is really economical, no wonder so many screws are used. If there are fewer screws, it is very easy to make poor contact.

Carefully reinstall the

From a structural point of view, water entering the keyboard will hardly cause other damage, as long as it is dried slowly. If sticky things such as coffee or beverages enter, the film may stick. If a beverage has entered, you can actually wash it with a lot of water and then dry it, without opening it for cleaning. Each key of the mechanical keyboard is independent, and when it is developed in the future, you can play with a mechanical keyboard.

Now the mechanical keyboard seems to be really cheap, and the entry level has been made in the early 100s in China. , the wave of changing mechanical keyboards is coming in waves . When Double 11 arrives, I want to change it. Do you have any recommendations for discussion?
