American Iai? ——Royal Ax Y87 three-mode hot-swappable mechanical keyboard unboxing experience

The box of Yufu Y87 three-mode hot-swappable mechanical keyboard is relatively long, and it will give you the illusion of a full-size keyboard in your hand.

After opening the box, you can see a diagram illustrating the connection method. There are 4 TTC quick silver switches v2 on the left side of the box, and the keyboard accessories are in the small box on the right side. So the entire keyboard box appears relatively long.

The included TTC quick silver switches can be seen as soon as you open the box. On the one hand, it is to show the appearance of the switch on the keyboard. On the other hand, if there is a problem with a certain switch, you can use these 4 spare switches to replace it.

Accessories: high-size support feet, key puller, shaft puller, 2.1m long aviation plug USB-C cable.

Yufu Y87 is a three-mode mechanical keyboard with 87 keys. The keyboard is matched with red and blue colors. The overall size of the keyboard is 369*143*37mm, and the weight is 1415g. It feels very heavy in the hand and is the best for daily desktop use. Good, but really inconvenient if you want to be portable.

The keycap of the keyboard is made of PBT material and adopts a two-color injection molding process. The characters on the keycap are thin and opaque. The keyboard is equipped with TTC’s Kuaiyin switch v2. This switch is an upgraded version of the Kuaiyin switch, so the suffix is ​​marked with v2. The Kuaiyin switch is a linear speed switch, and the life of the switch can reach 100 million times. The keyboard supports hot-swappable switches, and is compatible with 3-pin and 5-pin switches, as well as various types of RGB switches. This is the most convenient for players who like to use different shafts. Not only that, if there is a problem with the keyboard shaft, they can also be replaced and repaired by themselves.

Yufu Y87 three-mode hot-swappable mechanical keyboard comes with RGB lighting, and supports multiple lighting modes that can be set in the driver. The built-in 4000mah lithium battery of the keyboard can last for about 14 hours when the light is turned on, and about 350 hours when the light is turned off. If you want to achieve long battery life, it is best to turn off the light to use. The keyboard has a full-key conflict-free design, so gamers can use it with confidence.

Removable support feet

The support feet that come with the keyboard can be used on both sides, and can switch between 2 heights. With the included support feet, you can switch between 3 heights.

The gaps between the upper and lower shell edges are handled very rigorously, and there is no problem of different widths.

The keycaps are matched with red and blue. The PBT two-color injection keycaps are more wear-resistant, but the characters on the keycaps are opaque.

The surface graininess of the keycap is slightly thicker than the graininess on the side. I don’t know if this is intentionally designed like this.

From the bottom of the keycap, it can be seen that the small keycap has a slight burr problem, which feels a little bit harsh.

The problem of burrs on the nozzle part of the large key will be more obvious.

The large key position adopts the scheme of the satellite axis.

All the big keys on the keyboard are tuned very well without any sensual problems.

TTC fast silver shaft v2

TTC Quick Silver Switch v2 is a linear speed switch. The total stroke of the button is 3.4mm, the trigger stroke is 1.08mm, the trigger pressure is 45gf, and the life of the button can reach 100 million times. The speed shaft is characterized by a light actuation pressure and a very short actuation stroke. When I first got started, I had the feeling that it could be triggered by just a touch of water, and it was accompanied by a sense of rapid rhythm. After about 2-3 days of adaptation, I could fully adapt to the trigger rhythm of the fast silver axis. The shaft is factory-lubricated and the up and down process of the shaft is very smooth, and the bottoming is relatively solid.

After unplugging the switch body, you can see the internal space where the switch body is installed. The keyboard supports 3-pin and 5-pin switch bodies. The LED lamp beads are attached to the back of the PCB, and the height does not exceed the surface of the PCB, so it is compatible with any RGB or non-RGB. shaft.

The pins of the shaft body are sealed with glue to prevent high-temperature steam from penetrating into the shaft body during wave soldering.

The light-transmitting part of the shaft body is designed as a convex lens

The left side is the TTC fast silver shaft v2, and the right side is the TTC fast silver shaft. The main difference between the two shafts is the color of the shrapnel and terminals. The shrapnel and terminals of the TTC fast silver shaft v2 are silver-plated, so the surface is Silver, and the TTC fast silver shaft is common and alloy copper shrapnel and terminals, and the difference between the two can be seen through visual inspection. The main purpose of silver plating is to increase the durability of the shrapnel and terminals to prevent corrosion.

On the left is the TTC quick silver switch v2, and on the right is the TTC quick silver switch. The bottom of the switch body can also be seen that the mold is slightly different, and the degree of fineness of the rubber seal is also different.

Because the keycaps are opaque, the lighting effect of the keyboard is greatly reduced, and the light can only be reflected from the gaps in the keycaps. Nowadays, the keycaps of many small factories and the overall color scheme of the keyboard use opaque character keycaps, which makes the RGB lighting look a bit tasteless, but they are reluctant to give up this function. After all, it is still possible to change the translucent keycaps later. Lighting effects, but this ruins the overall color scheme of the keycaps and keyboard.

Summarize

The overall workmanship of the Royal Ax Y87 three-mode hot-swappable mechanical keyboard is good. The built-in double-layer silicone pad in the keyboard reduces the cavity sound generated by keystrokes and ensures the original knocking sound of the shaft body. The three-mode connection method has become the standard solution for small-sized keyboards in small factories, and it also greatly facilitates the user's connection switching between terminals. The keyboard has a built-in 4000mah lithium battery, which can last for about 350 hours without lights. If the keyboard is used for 3.5 hours a day, it can be used for at least 3 months. The design of the keyboard is still a customized solution. The keycap color matching and keyboard color matching are well integrated, but this makes the RGB lighting lack a stage for display. The keyboard supports hot swapping of the shaft body, which greatly facilitates the user to replace the shaft body by himself, and facilitates the operation of personalization and maintenance. The keyboard is equipped with TTC fast silver switch v2, which greatly improves the input speed of game players. It is like drawing a gun is always faster than drawing a knife. The shorter the process, the faster the speed. Comparing the American Iai with the Draw Sword Iai, the American Iai is the fastest within seven steps, and the American Iai is faster and more accurate within seven steps. Finally, let’s talk about the shortcomings of the keyboard. The workmanship of the keycaps is relatively rough, and the edges are not finely processed. For veteran players who pay attention to details, this is a pain point on the keyboard. I hope that the later products can improve the accuracy of the keycap mold.
