After the supply of Cherry control shaft body, the appearance of emerging manufacturers and shaft bodies on the market made the mechanical keyboard very lively. The most dazzling one is undoubtedly Kaihua Axis. Although there is still a gap between Kaihua Axis and Cherry Axis, obtaining the support of many manufacturers is also a successful step. Of course, the new axis is not just his family. The optical axis mechanical keyboard launched by the Bloody Hand Phantom is very special.

Blood Hand Phantom is not a new brand, and it can even be said that everyone knows it. Blood Hand Phantom is a high-end game peripherals brand under Shuangfeiyan. It was officially established in 2011, which represents Shuangfeiyan's ambition to enter high-end game peripherals. But I still have to complain that this bloody hand ghost still feels like a copycat manufacturer in terms of brand name and logo.

The Bloody Hand Phantom has already introduced a mechanical keyboard with the model of B540 and several game mice. Compared with its plain mechanical keyboard, its mouse has great characteristics and advantages, and has become a hot topic of discussion. Its mouse innovation in software and hardware is quite interesting. This time, its optical axis mechanical keyboard must be very interesting.

The concept of optical axis is relatively novel, which was put forward by the Bloody Hand Ghost himself, and it is also emphasized quite a lot in the packaging design. From the perspective of packaging design, we can find several key points of the optical axis, such as extreme response, zero wear, glare, etc., which we will leave to the handle of the axis.

The same selling points on the back and the characteristics of the optical axis are introduced. The Blood Hand Phantom B640 has rich features, such as multimedia keys, silicone keys, game mode, drive free combo, wrist rest and backlight. What's more interesting is its drive free combo. In fact, this function has a similar appearance in the mouse before the Bloody Hand Phantom. It can be called a hardware plug-in, quite invincible. Of course, the Bloody Hand Phantom B640 still has a strong domestic flavor in the outer packaging design, and I think the style can go up a lot if it is more concise.

In terms of accessories, such as operation guide, warranty card and key puller are necessary. The damage includes a simple silicone key cap, a noise reduction ring and a simple wrist rest.

The overall appearance of the Bloody Hand Ghost B640. If I don't tell you that this is a mechanical keyboard, you may really think it is a membrane keyboard with two flying swallows. Perhaps because of the birth of the brand, the Bloody Hand Phantom B640 and the previous B540 can actually be regarded as versions 87 and 104. On the whole, this kind of shape design really has the feeling of double swallow film.

View various details. The Bloody Hand Phantom B640 has set many multimedia keys on the key cap, and according to its brand characteristics, it also has various function keys such as lighting effect, drive free combo, etc. At least in terms of the functions of the keyboard itself, the Bloody Hand Phantom B640 is the largest number of mechanical keyboards I have ever seen, and has the largest range of coverage. The blood hand ghost B640 has a more angular border design. What do you think?

On the back are six anti slip pads and two foot stands, of which the foot stand is specially designed to open and close left and right. It is unclear whether the weight of the built-in steel plate is large or a design problem. The self weight of the Bloody Hand Phantom B640 is one third heavier than that of the common mechanical keyboard.

The label shows the symbolic characteristics of its optical axis.

In terms of wire material, the Bloody Hand Phantom B640 provides the HUB function, so the wire material is similar to Razer BlackWindle. The red and black woven wire material and the more sophisticated mold design are very impressive. However, as a high-end product, it's a bit unforgivable not to gild the interface. In addition, it's amazing to have to complain about the logo of the bloody hand ghost.

The Bloody Hand Phantom B640 provides extended functions of USB, headset and microphone.

In terms of key cap, ABS material and UV coating are actually used, and the words are transparent, so the workmanship is standard. More importantly, the bottom of the keycap of the Bloody Hand Phantom B640 is trapezoidal, which can effectively avoid the stabbing pain caused to the fingers during lateral pressure, which is a relatively interesting small improvement.

In terms of large key positions, the design of the Bloody Hand Phantom B640 is quite unique. In fact, the common mechanical keyboard has only two designs on the large key position, either the balance bar or the satellite shaft, which have no absolute feel. However, the satellite shaft has relatively low assembly costs and is difficult to adjust.

The Bloody Hand Phantom B640 combines the two. Do I call it the satellite shaft type balance bar or the satellite shaft type balance bar? In practical experience, it may be due to the reason of tuning, the hand feeling difference between several large keys is obvious, but it is relatively crisp in general.

When it comes to the specific feel, let's briefly introduce the optical axis. In terms of shaft body appearance, there is no obvious difference between the optical axis and Cherry axis. The same cross column axis makes the compatibility of key caps not a problem. The mechanical keyboard shaft body in the conventional definition is similar in structure, both of which are Cherry shaft structures. It realizes the difference of hand feeling through mechanical structure, and uses metal contacts to realize signal transmission.

The actual difference of the optical axis is actually in the signal transmission. The optical axis does not have metal contacts. It is actually realized by optical signals, which can be simply called infrared detection. As shown in the above figure, when in use, judge whether it is triggered by isolating the optical signal. That is to say, the principle of this optical signal has achieved ultra fast drying and hardening. Compared with the mechanical structure of the shaft, there may be a delay of 18~30ms, and the optical axis can be 1ms; In addition, in terms of service life, most of the metal contacts are between 30 million and 50 million, while the optical axis claims that there are 100 million times.

But just because of its triggering principle, it can not achieve the hand feeling diversity among the four axis bodies of Cherry axis: green, tea, black and red. It can only achieve the goal of going straight up and down, and can only adjust the force by adjusting the spring. It should not achieve the sense of paragraph. For friends who like the Green axis, they can basically choose to give up.

At present, the optical axis of the Blood Hand Phantom B640 has no loose axis and related actual axis body disassembly. Currently, the internal ones are all renderings. In terms of appearance, it has no change from Cherry, but in terms of LED, the square lamp it uses is larger than the common one, and the actual display effect and brightness also have certain advantages.

In terms of hand feel, I am not used to the optical axis. It may be because of the spring that there is a big difference between the shafts. Of course, this does not affect the use, but can be felt. Due to the structure, only Cherry red axis force is required for triggering, but with the distance to the bottom, the force increases significantly, and the knocking sound is loud. To be precise, when you hit the time axis at the beginning, it can be seen as Cherry red axis, and then become black axis. It may be easier to get tired when you first use it. Of course, it is still the same as mentioned above. It is a pity that the optical axis can not make the unique paragraphs of the green axis at present.

At present, the price of the Blood Hand Phantom B640 is about 680 yuan, which is also a relatively high-end price in the mechanical keyboard. In terms of appearance design, Bloody Hand Phantom has no great advantage. Compared with office film and domestic game style, many people may not like it. In terms of function, its unique drive free combo, HUB function, full backlight design and special key cap design can quite impress some game fans.

Speaking of the most critical optical axis, it may be the reason of the first product, but also the reason of its own structure. The optical axis is good enough in terms of technical completion, but the feel performance needs to be adjusted more carefully. In addition, its emphasis on 1ms response speed and zero wear is of little practical significance to most people. In the most critical hand feeling, its single choice is also easy to lose many consumers, which may be the biggest disadvantage of optical axis.
