Dismantling and dismantling, all-round analysis of Dujia's mysterious new product K620W three-mode wireless mechanical keyboard

On the eve of the Dragon Boat Festival, the author took the lead in getting the new K620W three-mode wireless mechanical keyboard from DURGOD. It is reported that the new keyboard not only supports hot swapping, but also improves battery life, and also supports automatic recognition of Windows/Android and MacOS/iOS dual systems , and the exterior design is also quite bright. In order to let friends in the general peripheral circle have a more in-depth and intuitive understanding of this new product, this sharing will conduct a comprehensive analysis from the functional appearance of the keyboard, internal dismantling, and product highlights. I believe that after reading this article, you will Get acquainted with this dazzling new work of Durga.

Since the author got the internal test version, the outer packaging of the temporary labor package is skipped. Fortunately, all the accessories are fully equipped, including transparent plastic keycap dustproof cover, USB to Type-C charging data cable, receiver expansion adapter (USB female port to Type-C female port), key puller, puller Axis controller, 2.4G wireless receiver and Option and Command keycaps matching for MAC system.

First of all, in terms of appearance, the materials used are as solid as ever. The new "island" theme color scheme not only adopts a double-layer laminated body design with a more three-dimensional visual impression, but also the entire keyboard is matched with three colors for the keycap part alone. Compared with the traditional single-color keyboard, it is more agile, and its appearance is indeed higher. Personally, I think the "Island" color scheme is more rigid, while the other dark, light blue + white keycaps and the "Echo" theme color scheme of the panel are more refreshing. Of course, in addition to the smaller 87-key arrangement, there is still an option of 104 full-key arrangements.

As a three-mode wireless keyboard, Dujia K620W supports three different connection methods: Bluetooth 5.0, 2.4G wireless, and wired. The automatic identification of the Android system makes it perfectly compatible with electronic devices such as desktop computers, laptops, mobile phones, and tablets, and achieves stable applications with full-key no-click and drive-free.

The status indicators of the keyboard are still set above the familiar direction keys, providing uppercase and lowercase status, WIN lock status, custom configuration file calling status and battery indicator. In addition, the first 3 indicators also take into account the Bluetooth and wireless connection feedback prompts.

In addition, the switching power supply and Type-C interface of Dujia K620W are designed on the front left side of the keyboard. Among them, the Type-C interface takes into account both charging and wired modes. I believe everyone prefers this design of separating the keys and wires.

Looking at the back of the keyboard, the DURGOD brand LOGO in the center is quite eye-catching. Does it feel like something is missing? Because it is an internal test version, there are no label stickers in the area above the LOGO. Not surprisingly, rubber feet are designed on the four corners of the back of the keyboard. The two-stage design of the feet is the high-low combination double-foot structure that Dujia is familiar with. In other words, it provides three different use angles, fully satisfying different needs. The usage habits of the crowd.

In addition, beside the foot support on the right side of the bottom of the keyboard, there is also a hidden storage compartment for the 2.4GHz wireless receiver, which can effectively prevent the accidental loss of the pocket-sized wireless receiver.

This time, the keycap of Duga K620W adopts the mold similar to its own K330W and the original high-quality PBT material two-color keycap of better quality. In terms of damage, it is very good. Based on the design considerations that this version of K620W is also not equipped with a lighting system, opaque two-color injection molding and closed characters are used to ensure that the characters will not be easily worn out even after long-term use. However, the white keys The hat characters are slightly less visible. As far as the quality of details is concerned, the reinforcement of the keycap lining and the thickness of the edge of the keycap can also be affirmed.

As for the core switch, the K620W is equipped with a customized switch—Crystal Switch—cooperated by Dujia and Jiadalong, and the switch is also equipped with a hot-swappable switch seat, which is convenient for users to replace the switch later. use. It is worth mentioning that the crystal axis jointly customized this time belongs to Jiadalong's CAP axis family, but on the basis of it, the technology is optimized and the axis is fully automatic. Whether it is an optional customized tea axis, The silver switch, red switch or silent red switch is smoother and more comfortable to use, and has a service life of up to 80 million times.

This time the author has a custom-made red switch version with a linear feel. Its trigger pressure is 45±10g, and it can be triggered by pressing down 2.0±0.5mm. Since the key trigger is short and the pressure is low, its overall The hand feeling experience not only has the lightness and smoothness of the cherry red switch, but also takes into account the sensitive and fast response of the cherry black switch. The straight up and down linear output is very comfortable and comfortable for daily text input or for playing games. In addition, careful friends will find that the shaft at the space bar on the keyboard is pink. Although the relevant parameters are unknown, judging from the feel, its pressure in grams is greater than that of the red shaft, which is somewhat similar to the black shaft. It's not too meaty on the space bar, and the rebound is quicker and quicker.

It is not too difficult to dismantle the keyboard. After taking off all the keycaps, you will see that there are 3 fixing screws on the metal positioning plate. Layer on top.

What is worthy of recognition is that sound-absorbing cotton is added between the keyboard PCB board and the keyboard bottom case, and a silicone pad design is added between the PCB and the metal positioning plate. The above two detailed designs can not only reduce typing resonance. At the same time, it provides a soft and quiet feel experience, and can effectively eliminate the percussion cavity sound and noise, making the sound of the key switch more clean and pure.

In addition, it is worth mentioning that the Durga K620W has also improved in terms of battery life. It is not only equipped with a 3600mAh lithium battery, but it only takes 3 hours to fully charge it with a 5V/2A charging device. Moreover, on the basis of ensuring high performance, low delay and stable output, through further reducing power consumption design, it has achieved an ultra-long battery life of up to 360 days in Bluetooth mode under the condition of an average use of 8 hours a day. Choosing 2.4G wireless can also achieve a battery life of about 200 days.

In general, the newly released Dujia K620W still continues the panacea attributes of its own K series products, not only can perfectly support three-mode wireless with full keys and no punching, but also adds dual-system automatic identification function. The high-quality feel and ultra-long service life of the customized crystal axis cooperated by Jiadalong also support convenient hot-swappable axis replacement. In addition, the battery life has been increased to an astonishing 360 days. Therefore, on the whole, the Dujia K620W with high appearance, strong performance and good quality is a new peripheral tool with careful design.
