The hands of the bloody product seems to have been on the unusual route. This time, the second generation B840 gaming keyboard hits the optical axis again. Compared with the traditional mechanical keyboard, the optical axis is totally different in structure and performance, not only in performance but also in performance. Has a faster trigger response speed, very clear and accurate on the signal without noise, the optical component trigger theoretically does not wear, oxidation, dust, no card key. Since the optical axis is definitely different from the internal structure of a conventional mechanical shaft, in order to achieve a mechanical axis-like feel this time, the optical axis of the second-generation B840 is specially designed to produce crisp shots and artificial sound. In addition, the LK2 has a 3mm key design , faster triggering, and a 25% reduction in total keystroke . It is suitable for high-frequency tapping. The shaft body also uses a dust cover and dust-proof handle to better isolate dust. . The optical components of the structure have dust penetrating ability and can effectively prevent dust from affecting the mechanical shaft. Although the optical axis keyboard has reached the second generation, it still seems a little strange and abstract to me, so this speaker brings everyone an enjoyable dismantling test and takes off the axis.

Packaging is still the same as the traditional blood product style, red and black with the style, a big blood handprint, the product model is B840 , this time the shaft technology uses the LK2 optical axis second generation products.
The back of the package is an introduction to the technical advantages of the optical axis, such as the 0.2ms button response, the key process of 3mm down 1.8mm conduction, trigger fast. The hit life of hundreds of millions of hits is free of double clicks and the "sound of gunfire" touch. Shaft body has a waterproof wall design to avoid liquid loading, keycap characters wear-resistant, cool backlight, full-key no rush, in addition to the driver can download the control key book, in the game when you do a key kill, the total He said the highlight of the product is still a lot of B840.
The keyboard was designed with a narrow frame, and the front panel is a metal panel that looks lighter and has no bloated feel. The keyboard is a 104- key American layout that mimics the mechanical axis of the robot. It is also suitable for office and Internet access. This time there wasn't any ugly sticker like the B740 on the keyboard. Instead , the product letters were made directly on the metal panel.
The position of the keyboard indicator light is not in the upper right corner of the traditional keyboard, but in the position above the function key area. There is no backlight effect after the power is turned on, which is a pity.
The keys of the keyboard are arranged in a low, high and high ladder arrangement, with cool backlight designs on both sides of the keyboard, and the effect of backlighting in the darkness becomes even more cool.
B840 's keycap and body design are more uniform. The four corners of the keyboard have a polygonal, tough style design. The metal panel's fixed screws are also in this position. The four corners of the keycap are also beveled.
There is nothing special about the layout of the buttons, the left side is still the common WIN button
On the right is FN combination function keys and menu keys
FN+ up and down direction keys can also adjust multi-stage backlight brightness
The key cap is a light-transparent injection key cap, matte surface, and the inside is reinforced. The key cap has a good hardness and is very strong.
Pull down the shaft to see, B840 's LK2 second generation optical axis is completely different from the traditional mechanical axis, it looks like the shaft body appears to be a little thin, wide buttons are also different from ordinary mechanical keyboard, ordinary mechanical keyboard is not a satellite shaft support, If it is not a wire structure support. The B840 is distinguished by the fact that the clips on both sides of the bottom of the keycap grip the wire on the bottom circuit board to support it.
The space bar is different. Two springs are added between the clip groove and the shaft body.
Around the shaft, there is a 6mm convex wall waterproof wall design to prevent liquid splashing. The keyboard surface of the suspension design is usually easier to clean dirt.
Four non-slip feet on the bottom and two red anti-slip adhesives on the raised bracket
Keyboard line is relatively long, there is a tie, non-plug design, nylon wrapped, the outlet has anti-break design.
Orange backlight effect after power on, cool backlight effects on both sides, looks not monotonous
Well, the following began to take off the shaft, the first is to pull out all the keycaps, instantly see the local metal panel, you can see all the wide buttons have support design
Remove the metal panel and directly see the exposed circuit board inside. The circuit board is black, the shaft body is indeed smaller than the traditional mechanical shaft, and the waterproof convex wall will wrap around one shaft body.
Turn over and look at the back of the circuit board. People with intensive phobias will cry! The bottom of the shaft can be seen as a four-column structure. The shaft is fixed on the circuit board in a different way from the traditional keyboard. There is no fixed solder joint. Instead, the plastic clamp on the shaft is stuck on the circuit board. On, so the disassembly will be easier. This optical structure of the optical axis is much simpler in disassembly than the conventional mechanical axis (except for the keypad).
The support portion of the wide button at the bottom of the circuit board consists of a white plastic base and a metal wire on the top
The cool backlight on both sides is achieved through the light bar
There are two symmetry luminous tubes above and below the LK2 shaft body. When the keyboard is powered on, it is usually in the light-emitting state. Pressing the button will block it. Basically this principle is similar to the principle of the mechanical shaft, except that the mechanical shaft passes through the mechanical shaft. The metal contacts are spaced apart. In contrast, the optical axis should theoretically be better than mechanical in terms of response speed and life. In addition there is a led backlight above the position of each axis LED.
Finally, the shaft body was dismantled, and the LK font gravure was printed on the shaft body. The design of the shaft body was quite ingenious. After dismantling, it was mainly divided into four components: the blue shaft cap, the small spring of the shaft, and the shaft. , Large springs, shaft base, usually the small black plastic shaft that presses the middle button of the shaft rotates and simulates the crisp gunshot touch like a mechanical shaft, achieving similar mechanical feel. The actual feel of the Ghost Optic Axis II B840 gaming keyboard is somewhat different from that of traditional metal mechanical axes. However, the optical axis does simulate the effect of a traditional mechanical keyboard. It is very similar to the keyboard sense of the Green Axis Keyboard and the traditional mechanical key path. It is 4mm , press 2mm conduction, and B840 key is 3mm , press 1.8mm conduction, so fast when the efficiency is still very high.
