"With Android With the popularity of 4.0 system, domestic tablet computers have gradually transitioned to the latest system. Benyi M8 (cloud Deluxe / 8GB), as Benyi's First Android 4.0 product, has attracted the attention of many consumers since it was launched in 2012. This product is equipped with Quanzhi A10 chipset, which has a good reputation in the industry. Not long ago, Benyi officially upgraded this classic product by a small margin. The new product has increased the available space. At the same time, there has been no small progress in the body material. This product is currently Benyi's main M8 (cloud luxury version / 16GB). This time, we got the real machine of Benyi M8 (cloud luxury version / 16GB). Through disassembly and evaluation, we can make everyone more clearly understand the internal structure of this tablet.
Benyi M8 (cloud Deluxe / 16GB) tablet
Before product disassembly, the author first introduces the main improvements of 16GB version compared with 8GB version.
Improvement 1: the ROM space is increased to 16GB.
This upgrade doubles the capacity on the basis of 8GB, and users enjoy more space to meet the needs of high-capacity users. Of course, users can also expand capacity by accessing TF card to achieve the purpose of capacity expansion.
Improvement 2: the shell is made of frosted plastic to enhance the feel and make it lighter.
Another major improvement of Benyi M8 (cloud luxury version / 16GB) is that the shell of the whole machine is changed from alloy material to frosted plastic material. The advantage is that the weight of the whole machine is reduced a lot and the machine won't feel too tired when holding it in your hand. In addition, the metal shell is easy to slip when the palm is sweating, and the frosted material can solve this problem.

The test results show that Benyi M8 (cloud Deluxe / 16GB) supports five touch at most and is still the mainstream level.
Start of formal disassembly
In the early stage of dismantling, because the author had not found a breakthrough point, it was almost violent at the beginning, resulting in the rupture of the screen at the top of the fuselage. If ordinary users need to dismantle the machine, they must make preparations. Common tools need to be in place. It's best to consult the dismantling tutorial on the network.

The correct disassembly method is to separate the top glass from the main board frame with a hard plastic sheet from the frame on the front of the fuselage. The two are fixed together by double-sided adhesive tape, and the bonding is relatively stable. Therefore, when removing here, pay attention to appropriate force, otherwise it is easy to break the top glass. When removing the top glass, pay attention to one end close to the camera.
Step 1: remove top glass
Because here, the touch sensing screen and the glass screen are bonded together. The cable of the touch sensing screen is connected with the motherboard. If the force is too large, it is easy to tear the cable.

After removing the outer glass, the rest of the work is relatively simple. We clearly see that Benyi M8 (cloud Deluxe / 16GB) fixes the display screen and the motherboard together through small screws, so we should remove these screws in the next step. It is very easy to find the right tool for disassembly. In the last step of screen removal, pay attention to the removal of cable arrangement, and do not be too hasty.
Disassemble the screen
After the display screen is removed, we can see that the internal layout of Benyi M8 (cloud luxury version / 16GB) is relatively clean, with few connections, which is neat. The battery, motherboard, WiFi module, speaker and other components are arranged in a rank. Of course, this is mainly beneficial to the high integration of the motherboard, and other components are basically no longer needed. Next, a few simple steps of disassembly can completely disassemble the whole machine. The following is the introduction of each part.

The first is the LCD screen. From the code on the display screen, we can find that this screen is from Chimei, the model is hl080na, and belongs to LCD, with a size of 8 inches and a resolution of 1024 * 768. The point distance is 0.05275 * 0.15825 (mm), the visual angle is 75 °, the color is 16.2k, the contrast is 700:1, and the response time is 10ms.

Next is the battery part. We can intuitively see that the built-in Benyi M8 (cloud Deluxe / 16GB) is a 4000mAh battery with a voltage of 3.7V. The battery adopts soft packaging, which can save cost and reduce occupied space. According to the official introduction, this battery can provide a maximum endurance of 220 hours (theoretical maximum) in the dormant state; The maximum duration of audio playback is about 45 hours, and the maximum duration of video playback is about 10 hours.

Here, the whole disassembly of Benyi M8 (cloud luxury version / 16GB) has been basically completed. Let's summarize and conclude the full text.
Disassembly summary:
In the early stage of the dismantling of Benyi M8 (cloud luxury version / 16GB), due to the insufficient preparations made by the author, it was impossible to start at the beginning. After dismantling the machine, we can see that the whole internal structure of M8 has been very simple. The main components inside the fuselage are integrated on a motherboard, and even wiring in other places has been saved. The author believes that this is mainly due to the good foundation laid by Quanzhi A8 chip during development, which not only makes the later development easier, but also makes the whole motherboard more integrated and reduces the accumulation of scattered parts. After disassembly, we found that, in fact, the composition of the tablet is not too complex, and there is still some residual internal space. Under this volume advantage, the author believes that the tablet can add more hardware to achieve more extended functions. Perhaps this is also one of the ways for the tablet to find its irreplaceable“
