4. 1: The tea axis is the most comfortable type, and the key stroke is also short
the black axis trigger bond is very short, but the physical bond is very long, and there is no sense of confirmation
green axis has a long key range (except for thunder snake black widow), but it has the most mechanical feel and is very straightforward to type
2: there is no difference between the game keyboard and the classic keyboard. It's just a non conflict technology as a gimmick. In fact, if you don't play the fighting game and the Jin band, there will be no conflict and basically no impact. Basically all the mechanical keyboards can achieve 6-key non impact, which is enough
3: the price is reflected in the workmanship, which is right. I have all the four brands you mentioned. Among them, filco is perfect in workmanship and good in feel. It's the one I recommend most. In fact, filco's price is not much. If I suggest, I won't regret buying filco
cherry's original factory is basically designed without steel plate, and its keyboard is very light, but it doesn't feel as good as filco's, and it always lacks a mechanical strength
in China, we can take advantage of the two keyboards, but to be honest, the introction of these two keyboards is OK. If you really want to play with machinery, the knoppoo with the same price is better than the PLU plus. Although the shaft of the PLU plus is original, there is still a big gap between the two keyboards and filco in terms of many small details. It's nothing to look at roughly, but it's uncomfortable to look at it carefully
4: ABS is the most commonly used key cap nowadays. It has a slightly granular feel and is easy to oil, but it has a good handle and long service life
POM has a kind of smooth feeling. Now there are few keyboards with POM keycaps
PBT is between two kinds of materials, which is the most expensive key cap. However, e to its poor plasticity, many PBT keyboards may deform after long use, but its oilless and delicate feel is the best in the key cap, which is rare now
5: the colored keycaps are not oiled, which is very difficult. If you have a set of PBT dip dyeing, you can find it on Taobao, but those are basically made by yourself. You have to investigate the process yourself. ABS dyed color keycaps are better than Kforce ones. I've bought three sets of them myself, and the quality is good, but ABS you know... Oiling is inevitable

5. Keyboard is the most commonly used and the most important input device. Through the keyboard, English letters, numbers, punctuation symbols can be input into the computer, so as to send commands and input data to the computer
today, the most commonly used input devices for personal computers are the keyboard and mouse
General 101 key or 102 key keyboard is named according to the arrangement of English letters, which is called QWERTY keyboard. Undoubtedly, it was born out of the English typewriter. Bill Gates once used this keyboard to illustrate the standard of "in fact": "the order of letters on English typewriters and computer keyboards is qwer

advantages

1. The most important part of mechanical keyboard is shaft. Mechanical keyboard has a longer service life than ordinary film keyboard, and a good mechanical keyboard has a service life of more than 10 years or even more than 20 years

2. After mechanical keyboard has been used for a long time, the change of key feel is very small, but the film can not achieve

3, The film has a single touch

4. The mechanical keyboard can achieve more than 6 keys without impact, and some mechanical keyboard can have full key without conflict, while the film keyboard with more than 6 keys without conflict is less

5. You can change the key cap by yourself, which is convenient for personality DIY

1. The price is on the high side. Because of the high cost, most of them are 400-800 yuan in the market, and it's not surprising that there are more than 1000 yuan

2 Although the keyboard has a long service life, it is poor in water resistance, so you need to be careful when using it

ABS

chemical name: Chemical Name: acrylonitrile butadiene styrene plastic

English Name:

ABS plastic (resin) is a terpolymer of acrylonitrile, butadiene and styrene (a stands for acrylonitrile, B for butadiene, s for styrene). It should be the most widely used material in the PC instry, such as chassis panel, monitor shell, keyboard and mouse, etc. it can be seen in almost all places. It has the characteristics of tasteless and non-toxic, can be used at very low minus 40 ℃, melting temperature as high as 217 ℃ (thermal deformation temperature is 93-118 ℃), strong shock resistance, not easy to deform, and good insulation, not easy to be affected by humidity and frequency

The key caps made of ABS are the most in all materials. Of course, the main reason is that the technology is mature and the price is cheap. From ordinary keyboards with tens of yuan to high-end procts with thousands of yuan, you can see ABS key caps. ABS keycaps are of various colors and can be made translucent to meet the needs of backlight, which is beyond the reach of other materials. The key cap made of this material is softest, not very hard, mild to the touch, and has a certain anti oiling ability, but not as good as POM and PBT

POM

chemical name: polyoxymethylene

English Name: polyoxymethylene

POM material is also known as saigang or Trane, which shows its hard texture. It can work stably between minus 40 ℃ and 100 ℃. Compared with ABS, it is not stable enough. It will decompose when it reaches 240 ℃. However, it can't exceed 100 ℃ for keyboard key cap. You don't have to worry about it at all, as long as you don't take cigarette ends to iron it. POM is a kind of linear polymer with high density and high crystallization, so it has excellent wear resistance, high strength, insulation and wear resistance. It has strong anti-oxidation and anti-corrosion ability. Resistant to hydrocarbons, alcohols, aldehydes, ethers, gasoline, lubricating oil, weak base and other organic solvents

The key cap of POM material is less than that of ABS, so it is most common in the original keyboard. It is a rable and simple material. POM is better than ABS in terms of rability and firmness, and its anti oiling ability is doubled. It will not cause oiling problems for at least two or three years (oiling varies from person to person). The handle is between PBT and ABS

Chemical name: polybutylene terephthalate (PBT)

English Name: polybutylene terephthalate (PBT)

PBT is a better material, which is harder than POM, and the whole material is like stone. High strength, fatigue resistance, deformation, high temperature is not easy to change, anti-aging effect is very good, so it can be said that it is the most stable key hat material. Good insulation

PBT is relatively rare, but it is often mentioned in the mechanical keyboard circle. It should be the most reliable and excellent key cap material at present. It is first-class in terms of oiling resistance and hardness, and has excellent anti-corrosion and anti-oxidation effect. It is said that it will never oiling. In addition, it is easy to decompose when it meets water in high temperature environment. It is precisely because of this characteristic that some shops specially use water to color PBT keycaps. The color of dyed keycaps does not fall off, which is natural and beautiful. Of course, the price is also very expensive. A set of 37 rainbow color keycaps in the main key area costs about 100 yuan

nylon

this material is widely used in automobile, electrical equipment, mechanical parts, transportation equipment, textile, paper machinery and so on. The most common is silk stockings, whether it's a gentle beauty or a fierce robber. Keycaps made of this material are not mainstream, but they are also sold in mechanical keyboards. They feel warm and moist, especially like jade

computers are developing and progressing. Similarly, as consumables, the relationship between peripheral procts and users is becoming closer and closer. Especially the keyboard has become the most frequently used input device. Keyboard structure has experienced the development process of mechanical type, plastic film type, contactless electrostatic capacitance type and conctive rubber type, and the printing method of characters on keyboard has also made great progress and improvement

a group of non engraving keyboard enthusiasts in the United States specially look for cherry company's customized procts and ask cherry company not to sell them to other regions within one year. This keyboard has a fatal attraction for many IT media editors who know how to read. On the contrary, many buyers who don't know about the keyboard feel puzzled about the non engraved keyboard. If you know the history of keyboards without engraving and like their pure color feeling, then they must be your best choice

laser etching

the so-called laser etching is to use laser lettering technology to burn black grooves on the keycap. Because the trace is linear, so the common laser etching keyboard arrows are hollow

many white keyboards on the market basically use this key cap technology. The main reason is that manufacturers take a fancy to its low cost. Although its proction line is expensive, its daily output is more than ten times that of other printing methods. Moreover, because it is burned and engraved handwriting, it can have very clear and firm handwriting without any other measures. Another reason for its large-scale proction is that it is environmentally friendly and will not proce harmful procts

However, laser etching also has several fatal defects, which determines that it can not be used in the proction of high-end keyboard. First of all, because laser etching belongs to etching, and does not use ink, so only a single black font can be printed, so the multi-color overprint design often used on high-end keyboard can not be achieved; Secondly, for the needs of appearance design and rability, most high-end keyboards use non white color design, and add wear-resistant fillers in the material of keycaps. However, e to the characteristics of laser etching, it can not etch the ideal clear handwriting on the non white and other fillers; Finally, the structure design and programming mode of laser etching machine make it best used to manufacture keyboard with standard key position design, ergonomics and other non-standard structure procts, which are difficult to be printed on ordinary laser etching machine. Because of this, laser etching is only used in medium and low-grade proction lines in large factories to take advantage of its advantages of high proction speed and low cost; In the proction line of high-end procts, e to higher printing quality requirements, we can only continue to use the traditional high-cost ink printing method

pad printing method is to use a group of letter type as the original font, brush the ink on it by automatic machine, and then press a group of soft rubber blocks on it, so that when the rubber block is lifted, the ink will be transferred to the rubber block, and then move the rubber block to the blank keyboard, once the rubber block is pressed, the ink will be printed on the keyboard

Before the advent of Phototypesetting Technology, books, newspapers and magazines were printed in this way. Compared with laser etching and screen printing, pad printing has no restrictions on printing conditions, and can be used to print any form of keyboard. But the disadvantages of pad printing method is also obvious, its printing speed is very slow, printing a keyboard time can make more than 10 laser etched keyboard down the proction line. Therefore, except for those small factories that can't afford laser etching machines, they have no choice but to use this printing method without any technical requirements. Large keyboard manufacturers generally only use it to print high-end procts regardless of cost. Secondly, e to the influence of its printing process, it is much more difficult to film the keyboard printed by pad printing than screen printing. Therefore, many keyboards printed by pad printing are not coated. Instead, the life of keyboards is enhanced by studying the composition of ink to improve the firmness of printing

screen printing

its principle is to cover a special screen on the blank keyboard, where the handwriting is hollowed out, and then scrape the ink from above, so that the handwriting will be printed on the hollowed out part

the feature of screen printing is that a layer of plastic can be coated with a special screen brush after printing. After drying, a layer of plastic protective film covering the printed handwriting will be formed, which can prevent the abrasion of the handwriting after long-term use. This is commonly known as the key disc laminating technology. Compared with laser etching, screen printing can print a variety of colors freely through repeated overprint of multiple screens, and there is no requirement for keyboard materials. However, e to the limitation of its printing method, it is still impossible to print the keyboard with too complex shape

immersion printing

immersion printing (also known as thermal sublimation method), is a different printing method from ordinary ink printing, which uses solid resin ink instead of common liquid pigment ink. This kind of ink will sublimate into a gaseous state at high temperature, infiltrate into the surface of permeable printed matter in the form of gaseous molecules, and then condense, thus forming a whole with the printed surface on the physical level, rather than just sticking to the printed surface like ordinary pigment ink, so its printing fastness is very high. And resin ink congenital in gloss, shape and other aspects of more excellent

the most common service of immersion printing is the "baking printing" of ceramic cup. When immersion printing is used for keyboard printing, the ink will completely "Penetrate" the PBT and ABS plastic inner layer of the key, so it is almost impossible to be worn off, and the text of immersion printing is highly three-dimensional and glossy. But the process of immersion printing is more complex than ordinary pigment ink printing, and the cost is very high, so only realforce keyboard uses this printing method

laser filling method

the principle of laser filling method is a bit similar to "tattoo", tattoo is to use a needle to make fine lines on the skin, and then fill with pigment, so that the color will penetrate into the skin lines, and will not be washed off or worn off later. The same is true of laser filler technology. First, print the text with laser etching technology (but it is lighter than the usual laser etching technology to ensure the smooth surface)
