Mechanical keyboard tossing notes, small questions and answers

There are countless hydrology to share below, let’s write some dry stuff today. Sort out my recent experience of tossing mechanical keyboards. The keyboard in my hand is broken, and friends who are capable of tossing about it have some ideas.

It may be that the natal year violated the Tai Sui, the keyboard was rattled before the Spring Festival, and the multi-key position failed and the keys were strung together. Enduring and using the membrane keyboard again, how did I endure it back then. The first time it breaks, check the forum, ask group friends, and watch videos. Most of them have no solution, or they are just the projects of Qifan. Taobao flagship store, third-party repair shop, mailing 10 + inspection fee starts at 40, excluding replacement parts for problematic parts. The problem is that my keyboard is a lump of aluminum, which weighs too much on the express scale.

The failure of the mechanical keyboard is nothing more than a bad axis, water ingress, bad diodes, and bad main control. I was the worst master controller to hang up. The keyboard circuit board is not high-tech, and it is a PCB board when it is disassembled, which is the same as the soft membrane keyboard back then.

AKKO Cool Creator 87 keys

It's been a long time, and it has entered the encyclopedia and become history.

Single key failure, trigger delay, most likely due to shaft failure, according to their own shaft, the e-commerce platform began to replace it for a few days. I don't play many keyboards, is it only the customized keyboard switch that can be plugged in and out at will? Many keyboards bought are still soldered on the PCB board.

There are very few of these guys before the toss, it’s better to buy a key puller, you will feel better when the solder melts and take the shaft. My hand hurts when I use the nail button, and I was pierced several times by the welding foot of the shaft.

What horizontal and vertical buttons cannot be triggered, just go to station B to watch the video. You need a multimeter, mine is from SDA. This little thing also has a buzzer gear, but the response is a little slow. According to the elimination plan of the video, find out the problem of your own keyboard, and then fly the enameled wire. I didn't buy enameled wires, so I destroyed the motor in my baby's electric toys, and there were enameled wires inside.

The PCB of my keyboard was not damaged. Later, I disassembled it and connected it to the computer. When I touched it, I could feel the heat of the main control at U1. Watching the video at station B will teach you how to test the order of the master needle tip. At this time, it was concluded that it was almost a master control problem. I asked the group of friends and said that I probably couldn't handle it.

AKKO keyboard 3087 model PCB is a virtue

Helpless, I didn't want to send it to the official for repair, so I communicated with the customer service whether the PCB was sold on delivery, but there was no result. Asking the PCB is the same, the answer is not sure. After sales didn't send me straight to the technical department.

I can only rely on the power of the seafood market. . .

Xianyu Browsing History

Comparing the pictures of the AKKO keyboard, which is also the 3087, some irons are disassembled, and some are garbage dumps.

Not surprisingly, the 3087 boards are all the same

I didn't see the difference between other models. AKKO also has model 3087S, which has a keyboard with lights. I don't know if the PCB is the same.

I have been shopping in Xianyu for several days, and there is no test keyboard at the garbage station, so don’t look at it if you are not looking for the axis. I found a few iron keyboards, and all of them were broken.

There is a problem with the Q rebound of this button when I bought it. I didn’t investigate the others. I won it for 60 yuan. Unfortunately, the switch body is AKKO’s own, not a cherry switch. There are bad cherry keys at the same price, but the keycap under Mt. Fuji attracted me.

Get the keyboard, just test it

No problem, start dismantling. The AKKO 3087 shaft is on the positioning plate and soldered to the PCB. It is very laborious to dismantle the shaft. After dismantling the Xianyu keyboard, it was found that the Tiezi keyboard had entered Coke, and the positioning plate was corroded. In fact, if there is no problem, I can move the keyboard motherboard part into my keyboard. Simply disassembled the 87+87 keys, put my cherry shaft on my positioning board, and its PCB.

The process is a kind of flow experience, and time flies. After washing its keycaps, the irons are still pretty good, except for the cola, it is actually much cleaner than my keyboard. . .

Final test, assembly tested perfect. A new look from the old.

Later, I believe in adding lights. After watching a few friends’ videos, I bought the recommended 234 square lamp, which is mainly due to the limitation of PCB and cherry shaft, RGB lamp beads and SMD lamps cannot be used.

Adding lights is a bit bad

With the lamp beads on, it can be used even in the dark.

I don't want to give up this aluminum keyboard, so it can be regarded as a small mud pit of the keyboard. That's it, everyone is welcome to communicate and exchange. I'm a newbie hahahaha
