① 100% collocation: 104/ 108 key; ②80% matching: 87/86/84 bonds; ③60% arrangement: 6 1/66/68/7 1 key, whether it needs convenient storage or office use, whether it needs a numeric keyboard, you must pay attention when choosing, don't blindly buy big names, and choose according to practicality.
ABS: Skin-like material, which feels good, but it is easy to get oily (look at your notebook keyboard);
PBT:PBT material is more durable, has a matte texture, and is not easy to produce oil; However, the manufacturing process is easy to deform and the cost is high.
Common keycap heights are: original factory, OEM, SA, DSA, XDA, etc.
Most mass-produced keyboards use original factory and OEM height keycaps, and a few also use high flat-chested spherical caps such as QX 1, XDA and DSA.
Key cap character engraving, engraving, engraving.
Orthographic lettering: lettering on the front of the keycap is the most common way;
Side engraving: the characters are engraved on the lower side of the keycap, which is quite simple from the front, and can avoid the wear problem of laser engraving or mimeographed characters;
No lettering: there are no characters, which are generally common in customization and suitable for blind typing and high play.
Common ones are: laser engraving, screen printing, two-color injection molding and thermal sublimation.
Laser laser engraving: The main advantage of using high energy density laser to irradiate the workpiece locally is low cost, and the key cap carved by laser may be worn, which can be avoided if it is carved on the side.
Screen printing: Cover a blank keyboard with a special screen, where the handwriting is hollowed out, and then scrape off the ink on it, so that the handwriting will be printed on the hollowed out part.
Two-color injection molding: made of two plastic materials with different colors. Make the characters in the keycap first, and then inject the complete shape of the keycap to the outside, so that the characters are not easy to disappear.
Thermal sublimation: using solid resin ink, the printing is very firm, the text is not easy to disappear, and smooth color effect can be made. It is difficult to use this process for ABS, and the characteristics of PBT material are more suitable.
Clarity: laser engraving > thermal sublimation > mimeograph > two-color injection molding;
Exquisite: thermal sublimation >> laser engraving = mimeograph > two-color injection molding;
Wear resistance: two-color injection molding > thermal sublimation > laser engraving >> mimeograph;
Cost: thermal sublimation > two-color injection molding > laser engraving > mimeograph;
The key structure consists of rubber cap and trigger switch. The rubber cap is located under the keycap and is generally made of silica gel, so the touch of the film button is generally soft and easy to collapse. Below the rubber cap is a trigger switch, which consists of three layers of films: conductive layer, insulating layer and conductive layer. Each key has a corresponding hole in the insulating layer.
When the button is pressed, the upper and lower films will contact through these holes to generate an electrical signal, so that the main control chip can know which button is pressed. Because the manufacturing process is simple and the material cost is low, the biggest advantage of the membrane keyboard is that it is cheap, the replacement cost is low and it is not afraid of flooding. If you accidentally get water, you can immediately cut off the power to dry, and the keyboard can still be used. If you don't have too much pursuit for the keyboard, choose a brand film keyboard with solid workmanship.
For example: Logitech K380
Each key of the mechanical keyboard is an independent mechanical structure, and there are many mechanical designs with different handfeel. Therefore, manufacturers will use colors to name and distinguish shafts with different handfeel, which reduces the cost for buyers to choose shafts.
Each key of electrostatic capacitance keyboard is an independent capacitance switch. When the key is pressed, the capacitance of the capacitive switch will change to generate a signal. The touch of the keys of the electrostatic capacitance keyboard has nothing to do with the way the keys generate signals, that is, the touch of the keys of the keyboard will be completely determined by the adjustment of the manufacturer.
Electrostatic capacitor shafts can be divided into three categories: Japanese Topray shaft, Topray shaft and mechanical shaft.
3.3. 1 Japanese gyro axis
Because the patents of capacitive switches are in the hands of Japan's Topre company, the Topre axis is the most traditional static capacitive axis. If you want to describe the feel of Topre axis, it is the feel of black axis+film, and the experience is very special. At present, only Topre's keyboard brands HHKB and RealForce are equipped with the Topre axis.
Top axis
Topre-like shaft is a kind of electrostatic capacitance shaft with similar structural design to Topre shaft, but it is obviously different from Topre shaft in fact, and it is different in the design of metal plate, push rod, base and other parts. At present, Ning Zhi is the representative of Topre axis.
mechanical axis
The mechanical shaft structure design refers to the electrostatic capacitor shaft of the mechanical shaft structure, so the actual feel is closer to the mechanical shaft, and it can also achieve a sense of paragraph that the Topre shaft can't do, which can be said to be an enhanced version of the mechanical shaft. At present, both Amilo and Daryo have introduced this kind of mechanical electrostatic capacitor shaft, which belongs to the least number of key shafts.
Most wireless technologies have a certain delay problem, which is not suitable for playing fps games, and the wireless version is definitely more expensive than the wired version under the same configuration.
In wired keyboards, many keyboards will adopt the design of separation of keys and lines. The advantage of this is that even if the computer does not have a USB-A interface, it can also use the connecting cable of the corresponding interface and wirelessly use an adapter to transfer the interface, which is more convenient.
However, when the keyboard is used with projection, tablet, mobile phone and other scenes, the portability and placement flexibility brought by wireless are reflected, and the wireless keyboard has qualitatively improved the cleanliness of the desktop.
At present, wireless technology can be divided into three categories: Bluetooth, ordinary 2.4 G and e-sports wireless technology.
4.2. 1 2.4 G is more stable than Bluetooth.
4.2.2 Bluetooth can connect multiple devices at the same time, with lower power consumption and each has its own advantages.
However, both Bluetooth and ordinary 2.4 G have some delay problems, which are not suitable for game enthusiasts.
4.2.3 E-sports wireless refers to Logitech LIGHTSPEED, Razer HyperSpeed and other low-latency wireless technologies, which have the characteristics of strong anti-interference ability and the delay performance is comparable to wired connection.
A general wireless keyboard supporting Bluetooth or 2.4G wireless is enough; If there is a need to play games with high response requirements such as fps, then either choose a wireless keyboard that supports e-sports wireless technology or a wired keyboard.
