What are the main production process steps of metal pc keyboard? Keyboard is an instruction and data input device used to operate computer equipment, and also refers to a set of function keys arranged by the system to operate a machine or equipment (such as a typewriter, computer keyboard). The keyboard is also a part of the keyboard instrument, and can also refer to the instrument that uses the keyboard, such as the piano, digital piano or electronic organ, and the keyboard helps to practice typing.
First, laser etching
The so-called laser etching is the use of laser engraving technology to burn black grooves on the key cap. Because the marks are linear, the arrows on common laser etched keyboards are hollow.
However, laser etching also has several fatal defects, which also determine that it cannot be used in the production of high-end keyboards. First of all, because laser etching is an etching, and no ink is used, it can only print a single black font, so that the multi-color overprint design that is common on high-end keyboards can not be done; Second, high-end keyboard for the need for appearance design and durability, ergonomic and other non-standard structure of the product is difficult to print in the ordinary laser etching machine.
Because of this, in the production line of large factories, laser etching is only used in the middle and low grade production line to take advantage of its fast production speed and low cost; In the high-end product production line, due to higher printing quality requirements, it can only continue to use the traditional high-cost ink printing method.
Second, pad printing method
Pad printing is a very old key cap printing method, because it is not very practical and inefficient, no longer used. Pad printing method is the use of a group of letters as the original font, through the automatic mechanical brush on the above ink, and then a group of soft rubber block on it, so that when the rubber block is lifted, the ink will be transferred to the rubber block, and then the rubber block is moved to the blank keyboard, the rubber block is pressed, the ink is printed on the keyboard.
Three, screen printing (a common way in ink printing)
The principle is to cover the blank keyboard with a special screen, where the writing is hollowed out, and then the ink is scraped from the above, so that the writing will be printed on the hollow part. Screen printing is characterized by a layer of plastic that can be printed with a special screen brush after the printing, which will form a layer of plastic protective film covering the printed script after drying up, which can prevent the wear of the script for a long time, which is usually referred to as the keyboard laminating technology.
Compared with laser etching, screen printing can freely print a variety of colors through repeated overprinting of multiple screens, and there are no requirements for keyboard material restrictions. However, due to the limitations of its printing method, it is still not possible to print keyboards with too complex shapes.
Four, including immersion printing (also known as thermal sublimation)
Immersion printing is a printing method that is completely different from ordinary ink printing, and it uses not the common liquid pigment ink, but solid resin ink. This ink will sublimate into a gas at high temperature, in the form of gaseous molecules into the permeable print surface after condensation, so as to become a whole with the printed surface on the physical layer, rather than just like ordinary pigment ink as “stick” on the printed surface, so its printing firmness is very high. Moreover, resin inks are more excellent in gloss and shape.
Five, laser packing method
The principle of laser packing method is somewhat similar to “tattoo”, tattoo is to use a needle to tattoo thin lines on the skin, and then fill with paint, so that the color will penetrate the skin lines, and later will not be washed off or ground off. The same is true of laser filler technology, first print the text with laser etching technology (but it is shallower than the usual laser etching to ensure the surface is smooth), and then use ink printing for secondary printing, so that the cured ink will penetrate the laser left by the score and remain in it, and will not be easily ground away.
The keyboard printed with laser filler technology, due to the secondary printing of ink, makes up for the laser etching font is not good and can not print color defects, and because of the laser scoring as the basis, its firmness is much higher than the simple ink printing. Personally, this keycap treatment method is a combination of laser etching and ink printing.
Six, hollow printing method
First of all, this method is almost all printed in this way on the keyboard of the phone. And only some of APPLE’s laptop keyboards use this printing method. This printing method is very simple to say, in fact, the main purpose of Apple computer to use this printing method is not to write firmly, but for beauty.
Because this hollowed out font is “engraved” out, it is more clear and bright than ink printing, and like a mobile phone keyboard, the backlight circuit can be installed below the keys of the hollowed out text, making the laptop keyboard like a mobile phone keyboard with excellent backlight effect.
Seven, two color forming
Two-color molding is the use of molds to combine two different colors of plastic together, using the difference between the two plastic colors to display the font. The advantage of two-color forming is that the font color is bright, the durability is high, and it is not easy to drop the word. If the manufacturing technology is good, the tactile performance of the key cap will be very good. The disadvantages are that it is difficult to show finer text, the color types are monotonous, the stroke complexity is low, and the fixed cost of its manufacture is expensive.
Eight, radium carving
Radium carving process has the characteristics of never fading and clear line.
How to find a good medical keyboard
How to find a good medical keyboard
In hospitals and clinics, doctors and nurses use computers, keyboards and mice to enter data at their workstations. Such items will be in direct contact with doctors and nurses, especially as we have not fully overcome the new coronavirus state, it is more important to use professional medical keyboards and mice, which can be easily disinfected, cleaned, and have a good typing experience.
Medical silicone keyboard, obviously the surface material of this keyboard is made of medical silicone. The medical silicone keyboard provides a comfortable and lightweight typing experience without causing any pain or wrist soreness, and typing without any sound. The one-piece silicone sheet has no cracks, so it can be thoroughly cleaned by flushing and can be sterilized with medicinal alcohol. The internal keys of the keyboard have silicone carbon particles and scissors feet can be selected, feel light, providing a very pleasant typing feeling. We make them white, and once the keyboard is dirty, it is easy for users to realize that the keyboard should be cleaned, because dirt and blood are easily found on the keyboard. Functions are similar to traditional plug-and-play keyboards. Different languages can be customized according to the need. Doctors and nurses will undoubtedly wear medical gloves all the time, so our medical keyboard is designed to be operated with gloves and wet hands. Simple and fast.
