Huawei's "MATE high-end series" finally occupied a place in the flat panel through Matepad Pro. The previous box also took the friends to enjoy its value. That is today, it is to see this MatePad Pro's internal world.
E analysis
As a flat panel, Haisi chip naturally accounts for the main position. How much is it?
EWSETECH engineers naturally also have a preliminary analysis of the cost of the tablet. Let's take a look at the cost of cost.
In the entire MATEPAD PRO:
China's cost is 71%, mainly region is the main control chip, non-electronic device, connector and screen
South Korea cost is 15.7%, mainly region for flash memory chip
Japan cost is 4.6%, main zone in the device, front camera sensor
US cost is 4.6%, main area in power RF assist IC, rear camera sensor
In these 1411 components, the cost is the following five components.
How many components are placed in this tablet? Let's take a look at the dismantling steps.

The Carto of the MatePad Pro Wi-Fi is located below the top left of the tablet, and the entity button is located on the left side and top of the camera. Carto uses metal materials for dual NANO card design, with a front end card supports a maximum of 256GB of NM card.
The rear cover is glass fiber, and white sealing adhesive is used around, and large-scale black graphite is used for heat dissipation. A total of 7 bubbles were posted at the four speakers. While these places are fixed, they can also have some buffering effects when the back cover is squeezed.
Since MatePad Pro supports wireless charging. Open the rear cover, the wireless charging coil is fixed in the middle of the battery by a long strip of radiant graphite sticker.
The BTB interface of the coil is fixed on the steel sheet, and the steel sheet is fixed by a screw, and the surface has a yellow insulated sticker. The whole machine is used for a total of 55 cross screws to fix each component. The internal integration of the tablet is very high, there is almost no remaining space.
MatePad Pro uses two tandem lithium polymer batteries, two batteries take up two-thirds of space, and the battery is secured with strong viscosity and is not easy to disassemble.
The total capacity of the battery is 7150mAh (rated capacity), the model is: HB27D8C8ECW-12, the battery cell is provided by ATL, manufactured by Shunda Electronic Technology.
The display and USB TYPE-C interface board is connected to the MatePad Pro battery with two FPC soft boards. The top has a microphone array with a microphone array FPC soft board. There are three microphones on the soft board.
The black fpc softboard is one end of the BTB interface and the other end is connected to the display using the ZIF interface. The interface is fixed with a thicker foam glue.
When the camera was taken, it was found that there was a metal bracket above, and a soft and hard bond sheet was fixed with double-sided adhesive.
The board is integrated with a power button, a volume control button, an LED flash, and a two microphone.
The camera is not special, so the shooting is not very good, only for everyday use.
13 megapixel rear camera uses Omni Vision Ov13855 CMOS photosensitive components, F1.8 aperture, and modules are produced by tilation.
8 megapixel front camera uses Sony IMX179 CMOS photosensitive components, F2.0 aperture, and credit international production module.
Four speakers certified by Harman Carton are fixed to the left and right sides of the flat plate, and the contacts are connected to the main board. There are foam glues in both sides of the speaker, and there is dustproof net and dust-proof cotton.
There are digital numbers on the surface for distinguish. Among them, the top 1 speaker has an FPC antenna.
The MATERPAD Pro uses a total of 5 PCB boards, which are motherboards, cardboard, two antenna plates, and USB interface boards.
The motherboard and the card slot plate are connected to the FPC soft board, and the motherboard is connected to a radio frequency coaxial between the motherboard, and the other antenna plate or the reserved plate is not connected to the other 4 PCB plates. The 4 metal shrapnels on both sides of the BTB interface of the USB interface board are connected to the right side of the tablet.
The screen and the middle box are fixed with a foam, and the bottom of the screen has a graphite heat, and the blockbusted cotton material and graphite sheet on the front of the block are used, and the screen is used to use the Tettop Technology GT7382 touch scheme.

MatePad Pro uses a 10.8-inch IPS tub full screen, resolution 2560x1600, screen is provided, model: TS108QDMAH0.
Summarize
Although Huawei MatePad Pro can be filled with parts, most of the space is occupied by the battery. The motherboard is also disassembled into 5 PCB boards, which will be independent of the antenna, the main control, and interface functions.
Many cross screws and foam adhesive are fixed internally. The heat dissipation is mainly through the surface of the body housing and the large area graphite material on the back of the screen. There is no such as copper foil and liquid cooling heat.
