I bought this keyboard in the United States with 4725 last year. The selling price in the United States is 149$, which is more expensive.……
When I first saw this keyboard, there was a strong sense of familiarity. Oh, yes, you can also see that this key layout and shape are almost exactly the same as CHERRY’s limited-production G80-5000. There are too many similarities between them. I also saw this keyboard picture when I googled 5000 and I was very interested in him.（Mainly interested in whether it can be changed into a mechanical keyboard, HOHO, copycat G80-5000HPMUS）, I bought this keyboard and another IBM brand new boxed keyboard when I was shopping together. Expensive…… really rice……
I didn’t expect much from him before, but I was more interested in his structure and appearance. I tested it on the computer as soon as I got it. The results really surprised me. The full keyboard is conflict-free. The appearance, structure and performance are the same as MX5000……
Maybe everyone is not very clear, but if you want to achieve keyboard conflict-free, it is not difficult, but the cost will be high. There are currently two ways（I don’t have much knowledge, I only know two kinds. Those who know other methods don’t hesitate to enlighten me.）, The first is the coded keyboard, and the second is to use diodes in the keyboard circuit like CHERRY to constrain to achieve a conflict-free effect. In fact, there is another one used by RealForce, but I really don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t know its principle.
But I haven''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t studied this in depth. I took a look, took 3 photos and put them away. Recently, a JS asked me to write about it. . . I''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''ll just write it on request.

If you want to know his working principle, the first choice is of course to dismantle. Only hands-on can have the truth. I want a certain mechanical keyboard of a certain brand. The appearance is really beautiful. Only when you disassemble can you know the workmanship inside. It’s not better than a handicraft workshop, where it is worthy of his price and market positioning.

 

This is the keyboard packaging. It is a very simple carton box with instructions and non-slip mats attached.（Buying separately means adding money）, Connecting line



See me change! It can be broken, this is just the first step

It can also be supported, MAXIM supports two high tilt angles, so that it is comfortable to use

The hand rest is detachable, and there are adjustable feet on it, suitable for different heights and angles

The first step is to remove the hand rest. The whole keyboard is fixed by bamboo shoots. The whole keyboard has only two screws. Sophisticated design!

Please note that this keyboard has a lot of moving parts and several sets of occlusal separation parts. The whole keyboard is composed of three parts, and there are complicated designs such as track and positioning. In this regard, the mold and the product The combination requires a lot of design and experimentation. The other parts of the keyboard that support the shell are the upper and lower covers of the two molds. The parts of this keyboard are subdivided and there are no more than ten or twenty parts that cannot be assembled, and there are also materials There is a big difference. ABS, nylon, and silicone are all used. If one of them has a problem, the keyboard will be over. So I said he has excellent design and excellent workmanship.

On the back part, the entire keyboard has a chassis（Not a car……）, Rails, brackets, upper and lower parts of the keyboard, where is the only two screws in the middle

The first step of disassembly is to remove the only two six-lobed screws, and remove the entire chassis, bracket, and rail.

The disassembled keyboard part is fixed by upper and lower card bamboo shoots. The connection in the middle is not plugged and unplugged. If the keyboard is broken, it is useless.

After disassembling the keyboard, the keycaps and upper cover are assembled together, which is more convenient to disassemble~~~

At this point, I was really surprised. In my day, I actually saw a conductive rubber membrane keyboard ……BTC. It was the first time I saw another manufacturer.

When it is deformed, the film circuit below is like this. It is very worrying about the life span. Fortunately, the angle of movement is very small and can be ignored.

The keyboard adopts a pluggable connection line, and there are two versions of PS2 and USB. The interface adopts RJ11 4-core crystal head. Will the blacked-out 6 channels be the USB interface part? Pure speculation, by then you will know if you disassemble it, or is it also applicable to the current interface, with USB support on the chip, just like the popular PS2+USB? I think the latter is very likely.

Note that the components next to the interface are light-emitting diodes, that is, keyboard lights. This is the first time I have seen circuits made on the film, and there is no need for soldering.

Close-up of the conductive rubber, if it is broken, you can replace it with the conductive rubber in the remote control.（Just kidding~）

This is roughly the principle. The conductive rubber touches the double E on the circuit to connect the two poles to create a starting point. The principle is extremely simple.

A close-up of the double E on the film. The BTC is printed on PCB. This film undoubtedly saves a lot of cost, but the color is somewhat different from the general film. I wonder if it is because of the high requirements and the good use of materials? In addition, there is a dark thing next to each electric shock, I don’t know what it is.（Is it a semiconductor?）. Moreover, this film is also a two-layer wiring, which is very similar to a double-sided PCB in a PCB, with a metalized perforation connection. It''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s just that his wiring has become film printing, and the metalized perforation has become two films that fit tightly.

I don’t know the so-called label……

I wanted to infer his principle based on the model of the chip, but it went bankrupt now. . . Asphalt package, there is nothing, and I don’t know the model or anything.

Others are soldered chips on the PCB, and the film is connected to the PCB through the PCB for keyboard control. MAXIM is very good at sticking the chip to the film directly. Yes, you are not mistaken. It is glued to the film. , Pay attention to the two hot melt adhesives on both sides. . . Sturdy~~~

Finally, I can see that the RJ11 interface can be removed. It is tightly attached to the film through the fixing on the shell. The design of the cow fork is very delicate.
