Mechanical keyboard dismantling ten: only need to charge once a year, is Dujia K620W worth starting?

That's right, I finally got my tenth fastest mechanical keyboard, and suddenly found that on the road of tossing the mechanical keyboard, my steps were estimated to be slow. After all, the wallet warning is not a joke, not to mention being nagged by the wife, if you ask for trouble and go home and kneel on the keyboard, and answer the phrase "I have done my own evil, I can't live", it will be a lot of fun.

Let me talk about the Dujia K620W I bought this time. This keyboard is a three-mode mechanical keyboard recently launched by Dujia. Secondly, the more practical three-mode, hot-swappable, dual-system automatic adaptation, and 87-key configuration combination; in addition, it is said that it can last for a whole year after charging once, which is especially friendly to me who often forgets to charge electronic devices.

All the mechanical keyboards I bought are domestic brands. In my experience, I found that the quality of the current domestic mechanical keyboards is very good. This is not only reflected in the materials used, but also in design, theme and color matching. , basically each brand has its own characteristics, impressive. From the appearance point of view, Dujia K620W adopts a double-layer laminated body design with a stronger stereoscopic vision. The three-color combination of gray, white and blue is simple and at the same time, it also brings some jumps, which is very attractive.

In terms of function adaptation, Dujia K620W not only supports wired, Bluetooth and 2.4G three-mode connections, but also supports simultaneous connection of multiple devices. We can quickly switch through the combination of keys, which is very convenient. In terms of compatibility, Durga K620W not only supports the windows system, but also adapts to the mac OS system. In addition, IOS and Android systems are also perfectly compatible.

Looking at the back of the keyboard, I actually prefer this kind of sharp-edged design, which is very tough and has a good texture. I believe this is also the design style that many mechanical men prefer. Three-stage height adjustment, four-corner shock-absorbing feet, hidden 2.4G receiver design, necessary and very practical design.

In terms of dismantling the keyboard, I think I am quite experienced personally, so after receiving this keyboard, I am not afraid, so I picked up the tool and disassembled it.

Before disassembling the Duga K620W, we can take a look at the keycap of this keyboard. It adopts the high-quality original high-quality PBT material keycaps, which are relatively more comfortable to the touch and have better wear resistance. Compared with office keyboards, it is not easy to be "oiled" to affect the touch. The service life is also relatively longer.

In fact, when many friends choose mechanical keyboards, they also choose keycaps according to their own preferences. In addition to the original height, we can also choose different heights such as OEM and MAD. However, it is recommended to experience keycaps of different heights first. Thinking about it again, after all, everyone's hand condition and typing habits will be different, so we can't say which one is better, OEM, MAD or the original height.

Well, now the disassembly of Duga K620W is officially started. Similar to most mechanical keyboards, the first step in our disassembly is to disassemble the keycaps. This part is basically not difficult. Some keycaps can be removed directly by hand, while others You need to use a key puller, so I won’t go into details about this.

In terms of keycaps, I carefully observed the large keycaps of the Duga K620W. For example, the longest space bar, as can be seen from the picture, the sublimation coloring of this space bar is very uniform, and the texture is also very good. , the blue color also looks very positive and comfortable, and the details are handled very well, without glitches or small problems that affect the look and feel and use.

Look at the back, this should be the keycap with built-in ribs that I have seen, three horizontal ribs plus eleven vertical ribs, it is difficult to think of problems with this keycap.

Before removing the switches, I recommend removing the keyboard case first. The shell of Duga K620W adopts a double-layer laminated design, so when disassembling, we need to remove the white panel first, and then remove the black middle frame. When removing the white casing, I overturned the car. Since the top of the black middle frame was too tightly connected to the casing, I was unable to do so when removing it, which eventually caused a slight deformation on the top of the middle frame. Therefore, it is recommended that friends who want to disassemble use tools as much as possible during this step, and do not use force blindly.

In terms of shafts, Durga K620W provides four types of shafts to choose from, which are red shaft, brown shaft, silver shaft, and mute red shaft. Only one of the brown shafts is a paragraph shaft, and the other three are all linear shafts. . So when I bought it, I basically had no other choice. I bought the tea switch directly. After all, I prefer the texture and sound of the paragraph switch.

From the parameter point of view, the total stroke of the tea shaft I use is 4mm, the trigger stroke is 2.0mm, and the trigger force is 55gf. This should be said that the trigger stroke, trigger force and total stroke are too large. If you have not been used to it for a long time, you may I feel that typing is a bit tiring, but if you like the sense of paragraphs, you can't go wrong with choosing a tea shaft.

This is a data comparison of several shafts, you can experience and choose according to your own needs.

The large key position of Duga K620W adopts the satellite switches that are used more recently in mechanical keyboards, and all the satellite switches have been treated with lubrication, which will be smoother and easier to use when using.

After dismantling the slightly troublesome shell and middle frame, the disassembly of Dujia K620W becomes very simple. Remove the middle positioning plate + silicone pad and PCB board, the three parts are very tightly connected, fixed by two sets of front and back screws, and the reliability is good.

Then, we directly complete the disassembly at one time. From the picture below, we can basically see all the components of the Durga K620W. In addition to the keycap and shaft body, we can see the upper cover, middle frame, metal Positioning board, silicone cushion, PCB board, sound-absorbing cotton and bottom case.

The positioning board of Duga K620W is really heavy. I estimate that less than half of the weight of the keyboard is on this board. This positioning board also assumes the role of a "load-bearing wall" similar to a house, ensuring the structural reliability of the entire keyboard.

The silicone cushion layer in the middle is also relatively thick, which can effectively avoid the interference between the PCB board and the metal positioning plate, and play the role of cushioning and noise reduction.

As the core of the mechanical keyboard, the workmanship of the Duga K620W's PCB board should not be too faulty. Except for a power line and a 2.4G receiving line, there are no other flying lines on the entire PCB. If you observe carefully, you will find that the solder joints are very full at all soldering points, which can effectively avoid the failure of keys due to weak soldering and desoldering. On the back of the PCB board, we can also see that a small area is also designed with a sound-absorbing pad, which is full of details.

In addition to the silicone gasket we saw earlier and the small-scale sound-absorbing gasket on the PCB, there is also a whole piece of noise-absorbing pad on the bottom case. Through the design of adding silicone pads, cushioning sponges, and sound-absorbing cotton between these layers, the stability and noise-canceling ability of the Durga K620w are further improved. After a long period of use, we can feel the keyboard's input experience. , Excellent performance in noise cancellation.

On the bottom shell of Durga K620w, we can see a fixed battery. From the parameter information of the battery, we can see that the capacity of the battery is 3600mAh. In addition, this is a mechanical keyboard without RGB lights, which makes Durga K620w The battery life has been greatly improved. According to official information, on the basis of 8 hours of use a day, this battery can meet the battery life of Durga K620w for nearly a year. If you add rest, go out, and charge once a year, it is not a problem at all.

The most interesting part of the mechanical keyboard is that in addition to the customization at will, there is also some fun in restoring the keyboard after disassembling the whole keyboard.

After experiencing it for a period of time, I disassembled and restored the Durga K620W in an all-round way, so I believe that many friends already have their own answers to the question of whether it is worth buying.

But as far as my personal experience is concerned, I think it is recommended to start with. First of all, this Durga K620W is relatively simple in design, the overall texture of the keyboard is also very good, and the details and workmanship are in line with our expectations for a high-quality domestic mechanical keyboard. Secondly, in terms of function, three-mode, multi-device connection, and multi-system compatibility are one of the main selling points of this keyboard; moreover, the super endurance of Dujia K620W really adds a lot to this mechanical keyboard After all, forgetting to charge is something that many people often encounter; finally, from my dismantling of Duga K620W, this keyboard is not only very well handled in appearance, but also in internal structure, board selection and processing. It's pretty good.
