Now everyone is watching the big screen shocks, the traditional TV is also getting bigger and bigger, even more than a hundred inches, but the installation and the price of the two sides to make many people discourage, so in recent years the competition in the projection market has become more intense, users The viewing habits are slowly being changed, the price is relatively cheap, and it is easy to project projections of more than a hundred inches, which are more favored by users. In this projection market, nut projection has always been a stylish new appearance, high hardware performance, well received by users. The recent rate of new production is also amazing. In the physical resolution of 1080P, the Nut J6 was released shortly afterwards, and the Nut C6 was newly introduced. Whether the new products are as good as they always are, let's experience it with me. 
Eight-layer PCB can be used to add two additional layers, or two planes can be added to improve EMC performance. Most eight-layer circuit boards are superimposed to improve EMC performance, rather than adding additional wiring layers. Compared with 6-layer circuit boards, the cost increase percentage of 8-layer PCB is less than that of 4-layer PCB to 6-layer PCB. Therefore, in order to improve EMC performance, the cost increase is reasonable. Therefore, most 8-layer boards consist of four wiring layers and four planes.
In short, 8 layer PCB are usually used to improve the EMC performance of circuit boards, rather than increasing the number of layers.
No matter how you decide on the stack layer, it is not recommended to use an 8-layer PCB board with six wiring layers. If you need six routing layers, you should use a 10 Layer PCB board. Therefore, the 8-layer board can be regarded as the six-layer board with the best EMC performance.
All signal layers are adjacent to the plane, and all layers are tightly coupled. High-speed signals are buried between planes, so planes provide shielding to reduce the transmission of these signals. In addition, the circuit board uses multiple grounding layers to reduce the grounding impedance.
The 8-layer prototype FR-4 PCB is an 8-layer circuit board, which is firmly stacked together with predefined and reliable interconnection between layers. The 8-layer FR-4 PCB has more complex structure. JHYPCB is a large enterprise located in Shenzhen, China, which can manufacture 8-layer prototype PCB.
JHYPCB can provide you with multi-layer PCB board in accordance with RoHS standard. With laminated material, it can match high temperature in assembly process. Importantly, some lead-free assembly processes will require laminated substrates to withstand temperatures exceeding 260 degrees Celsius or 500 degrees Fahrenheit over a longer period of time. To solve this problem, we have high temperature laminates in stock, so that our customers can meet the higher temperature cycle requirements of some lead-free assembly applications.
[excellent appearance]
For a digital product, everyone will be more concerned about the appearance and function, so out of the box will not do anything, go straight to the theme. The appearance of the nut C6 is similar to that of the previous G series. It is not only a lot smaller than the J6 that was released earlier, but it is only 194.5*48mm in size, and it is also very light. It is convenient for a machine to use in different areas such as a bedroom, a living room, etc. at home. .
Nut C6 uses a high-quality light machine, brightness up to 700ANSI lumens, compared to G1 increased by 150%, a resolution of 1280 * 800, during the day will also be excellent viewing results.
In the projection ratio, the nut C6 uses a short focal point of 1.2:1. It can project a hundred-inch screen without a distance of 3 meters. This is very suitable for users who are experiencing high house prices and small household sizes. Of course, if the conditions allow, nuts C6 can project a maximum of 300-inch giant screen, at home can experience the theater giant screen-like shock.
Behind the fuselage rich interface, from left to right are: S / PDIF OUT audio jack, HDMI interface, USB3.0, DC power interface, USB2.0, Ethernet interface, and a remote control signal receiving window. The rich interface guarantees the extensibility and playability of Nut C6, allowing it to show off in more places.
In terms of sound, two 5W speaker units are built in the compact body of the nut C6. Symmetrical HIFI sound design is used, and three-frequency dynamic tuning technology is adopted. The sound quality can be adjusted for up to six months and the three-dimensional sound is enhanced. Surround sound effect.
The sound effects actually confirmed the nut's contribution in these years. Compared to other brands in the home, the sound quality of the nut C6 is very shocking, and there is no need to pick up a good Bluetooth stereo. Of course, if you are an audiophile, you can get better audio equipment.
Nut C6 is covered with hollow holes made by CNC finishing in a circle on the body. In addition to being a speaker hole for pronunciation, it also has a heat dissipation function. The built-in cooling fan sucks wind from one side and the other side winds. , greatly improved the cooling effect, to ensure the machine has a longer life.
In the top of the nut C6 also hidden a power button, using a touch-type design, only after the power is turned on that circle of red LED light will be found, touch boot turned white, the device running status at a glance.
There are several small designs at the bottom of the fuselage, and long strips of arc-shaped non-slip mats have greatly ensured the stability of the nut C6 on the tabletop; two circular pads on the front end can be screwed out to raise the projection angle. Do not need to use other things to uplift; in the middle of the 1/4 international standard screw holes, the projector can be mounted on a tripod, or can be equipped with optional accessories for lifting.
For a small remote control, nuts are also joined with its unique design, full of sense of technology. Compared to ordinary remote controls, the two focusing keys on the lower left are particularly noticeable. When moving over the projection, manual focusing is required, which is more convenient than some focusing buttons on the body.
ã€JmGO OS System】
The reason why projection is popular nowadays is closely related to its own system. Nut C6 is equipped with a new JmGO OS system based on Android's deep customization. The interface is clear and concise, functions and contents are clear at a glance, and it is as easy to use as an Android phone. Convenience.
In terms of content resources, the nuts C6 are refined to 26 channels, and in-depth cooperation with the giant iqiyi of the video supply industry to create a super video library, whether it is popular TV dramas or front-line movies will be updated. Of course, it also supports the expansion of the download and installation of Youku video, Sohu video, Tencent video and other audio and video software.
In terms of projection image settings, digital zoom and keystone correction are supported in addition to brightness, aspect ratio, hoisting mode, and rear projection mode. In short, the system content and various settings of nuts C6 are reasonably distributed. It takes a few minutes to reach the machine and it is easy to get started.
[sharp and delicate projection effect]
So how is the projection effect of the nut C6? First, compare several projections with the real picture in the computer. From the comparison chart, you can see the color reproduction ability of the nut C6. It is basically close to the original picture, no color is too bright or the image is panned. White situation.
A separate projection diagram will not produce a large-screen shock effect. Although the nuts C6 can cast a maximum of 300 inches, the average family does not have such a large wall. The size of the projection on the map is about 120 inches. After adding people to the reference object, it is enough to see the size of the traditional TV screen. Some people here may say that there are also 100-inch LCD TVs, but the price of tens of thousands of dollars is not affordable for ordinary families. It is necessary to know that the price of nuts C6 Taobao raised only 2599.
If you project such a large picture, will you be very grainy when you look closely? Measured close to the shooting not only did not feel obvious particles, but the details look more clearly, after all, the resolution of the nut C6 also reached 1280 * 800. Of course, if you look close to the wall, you can still see the pixels of the square. This is even if the TV is the same.
Then the projection of 700 ANSI lumens will affect the viewing in the presence of light. The above is a comparison of the actual effect before and after turning on the lights. It is clearer and more intuitive to use the same picture. It turns out that although the picture is whitened, it has not been affected much. I am still under the direct lighting of the downlight on the side. If it is The chandeliers in the middle of the living room have less impact.
As a projection, everyone's primary goal is to watch movies. In fact, playing games during leisure time is also very good. Especially if you have children at home, you can download simple games that the remote control can control. For adults, Nut C6 is equipped with a quad-core processor, a 4-core GPU, a 1GB RAM, and a 16G ROM memory combination. Some ordinary mobile games don't have a problem basically, and they have a USB interface to support the mainstream of the market. Gamepad to control.
to sum up:
For this new C6 nut, the appearance of the basic or continuing the classic appearance of the G series, stylish and full of sense of science and technology. The design of 700 ANSI lumens, with a pricing of less than 3,000, enriches the nut products, giving users more options, and with regard to the current market, the brightness of nut C6 within 3000 should be the highest. Through the actual experience, all aspects of the performance of the nut C6 are not disappointing, if you also want to experience a large screen, leaving the home without a cinematic viewing effect, then the nut C6 is indeed a good choice.
