From Huawei's product line, the high-end market has been adhering to the dual flagship strategy, Mate series and P series, and the Mate series is the flagship flagship. On November 14th, Huawei held a grand new product launch conference in Shanghai, officially releasing its large-screen flagship products Huawei Mate 9, Mate 9 Pro and Mate 9 Porsche Design for the domestic market. The Mate 9 Pro and Mate 9 Porsche Design are designed with a front and back hyperbolic design. The screen is 5.5 inches + 2K, the fingerprint button is on the front side, and the Mate 9 is 5.9 inches. The surface design is eliminated and the fingerprint is still on the back.
Huawei Mate 9 Dismantling: Multi-protection, flawless, secure and fast charging The Huawei Mate 9 series released this time, in addition to the changes in design, the performance configuration has been greatly improved again, equipped with Kirin 960 processor and Leica that can compete against this year's flagship platform. The second-generation camera's 2x dual-camera zoom, SuperCharge fast charge, and artificial intelligence learning create an 18-month slow-changing experience. Regardless of the ultimate performance or experience, Huawei Mate 9 is once again eye-catching.
Negative LCD screen
Huawei Mate 9 normal version uses the same negative LCD screen as Mate 8, although it does not use non-curved screen design, but covers 2.5D curved glass, curved glass curve and body frame natural transition, arc R angle, arc The face frame and curved back cover make the entire phone feel comfortable. The normal version of Mate 9 uses a virtual Android button built into the screen. The button position is very concentrated and the operation is very convenient. The top of the screen is still the design of the earpiece, the light opening, and the front camera. The front view of the whole machine is very integrated.
Middle frame adopts metal wire drawing process
The middle frame of the fuselage adopts the metal wire drawing process, and the metal chamfering process polished by the CNC drilling and cutting edge process can effectively improve the face value of the machine while ensuring the hand feeling. The back is still a classic three-stage structural design, the overall treatment with sandblasting technology (ceramic white plate sprayed a smooth white coating on the metal surface), cut a knife up and down, using plastic hidden antenna plus the overall sandblasting effect will be " The three sections are integrated into one. Huawei Mate 9 follows a symmetrical design style. The Leica dual camera is centered vertically, and the flash and laser focus components are separated on both sides.
Huawei Mate 9 detail design
It is worth mentioning that the Huawei Mate 9 regular version of the back shell is designed with a curved shape, which brings a more superior feel to the machine. Of course, it also poses a challenge to the production process. Because the arc of the back shell is designed, it is not in the same plane. This requires the CNC machine to have a very high grinding precision to ensure that it can be ground in a three-dimensional space with high-precision chamfering. From the final effect, Huawei once again makes us feel the hard process.

Knowing so much, you can see that Huawei Mate 9 is amazing enough in appearance, performance, etc., then will its internal work be equally excellent? Next, let's take a look at the disassembly. (This dismantling model is Huawei Mate 9)
The first step: Shut down and start disassembling. First, you need to shut down. After the phone is completely shut down, remove the SIM card slot. Huawei Mate 9 adopts the design of single card tray and two card slots. The two upper card slots are Nano-SIM card slot and "or or card slot". In terms of network standards, the two card slots of Huawei Mate 9 support the full Netcom network standard.
Part 2: Remove the SIM card slot
Thanks to the support of the Kirin 960 with a new self-developed full-mode modem, Huawei Mate 9 supports LTE Cat.12 and four-carrier aggregation (4CC CA) for the first time in the industry. The peak download rate is up to 600Mbps, the Internet speed is faster, and the network signal is more. it is good.
Remove two five-pointed plum screws
After removing the SIM card slot, carefully observe the surrounding of the fuselage. There are two five-pointed plum screws at the bottom. At present, most mobile phone products are designed with two screws for fixing the rear shell at the bottom, and two five-pointed plum screws are decisively removed.
Exploratory separation using suction cups
Then, I chose to use the suction cup to tentatively separate the screen body part from the back shell. At first, I just carried out a simple â€œpullâ€. After several attempts, I found that the Huawei Mate 9 is very fixed. It seems that some need to be added. Strength, repeated attempts to separate, it can be said that it took a lot of effort to separate a small gap, decisively insert the crowbar, and then use the plastic blade to try to insert the screen cover and the back of the fuselage from the bottom of the fuselage The gap between the shells.
Crowbar + smashing piece
The smashing rod combined with the swaying piece, separated from the bottom of the fuselage at a little bit, and it took some effort. With the "squeaking" of the buckle trip, the screen body part was finally separated from the back shell.
Fingerprint identification module cable should pay attention to
One thing to note here is that in the mobile phone with the rear fingerprint identification scheme, when separating the back cover, be sure to pay attention to the fingerprint identification module to connect the cable. After opening the back cover, first disconnect the battery cable, then use the smashing rod to break. Open the fingerprint to identify the connection between the cable and the motherboard.
Back shell interior design
The fingerprint identification module, the flash, the volume addition and subtraction keys, and the power key on the back shell are integrated on one of the cables to be connected to the main board. Heat-conducting foam is designed in many parts of the entire rear shell to further enhance the heat-dissipating area, so that the body is always at a suitable temperature to ensure the user's experience.
The back shell is thickened by injection molding to prevent falling
On the back shell of the fuselage, the corners of the most easily bumped are thickened by injection molding, and the body of the screen is designed with metal buckles, which is why Huawei Mate 9 is so difficult to remove. In fact, such reinforcement processing is rare in smartphones, and Huawei is one of them. The surface of the antenna at the top and bottom of the rear case is gold-plated to ensure long-term use of these locations is not easily corroded.
Huawei Mate 9 motherboard true face
Now, I finally see the true face of Huawei Mate 9 motherboard. The inside of the fuselage is a three-stage structure. The top is the motherboard, the middle is the battery, and the bottom is the small board. The interior of the fuselage is very tightly designed to take full advantage of the space inside the fuselage. In addition, all cable connectors and chips are protected by a metal cover to ensure that they are not detached from the motherboard under impact.

Next, remove the main part of the fuselage - "board". Before removing the motherboard, you need to disconnect the power cable first. Before then, remove the graphite sticker. The power cable is protected by the metal baffle. There is a screw fixing. The surface of the metal baffle fixing screw is affixed with a white tamper-proof sticker. Deleting it means Will lose the warranty, so the friends should not arbitrarily disassemble, otherwise they will lose the official warranty.
Disassemble the motherboard process, first power off
Disconnect the power cable, and then disconnect the other two long cables, one is used to connect the bottom PCB motherboard, the other is the connection screen and the touch screen module, the same applies to the insulation rod to prevent the electricity Hardware failure.
Remove all fixing screws
Continue to remove all the fixing screws on the motherboard.
Starting from the P9 series, Huawei began to cooperate with Leica to adopt a dual camera solution, using black and white + color two cameras to achieve better imaging performance than traditional single cameras. This time Huawei brought it to the Mate series. This program is called the â€œSecond Generation Leica Dual Cameraâ€. Next, take down this group of cameras and find out.
Disassemble the rear camera
The cable connection of the main camera is still fixed by the metal baffle and the screw. The same method is used to remove the camera and remove the camera. The camera on the top is Monochrome black and white camera, the bottom is a color RGB camera, a combination of 12 million pixels + a 20 million pixel, the maximum aperture is f / 2.2, focal length 27mm. From the removed lens module, you can see the text LOGO of LEICA CAMERA AG, which may be regarded as the smallest lens of Leica.
Leica double shot close-up
Among them, the color camera uses a traditional RGBG Bayer array to record color information in the picture. The other camera, called Monochrome, removes the dichroic filter on the CMOS, and the amount of light entering is several times that of a normal Bayer array CMOS. All incident light is transmitted directly to the sensor and captured, so the pixel details can be effectively improved. The Huawei Mate 9 has increased the number of pixels of this black and white lens to 20 million, and the detail performance is worth looking forward to.
Leica double shot close-up
In addition to the lens and CMOS, the Kirin 960 is optimized for dual-camera, using Hybrid hybrid focusing technology, which can select the most suitable focus mode according to the camera environment. The upgraded PrimISP 2.0 has built-in HD HD hardware depth graphics processor and enhanced optics. Zoom effect, support 4K video anti-shake; also supports black and white dual camera real-time processing technology to capture more details.
Disassemble the front camera
After the rear camera is disassembled, let's take a look at the front camera. The front camera does not have the design of the metal baffle and the set screw, so it can be removed directly using the pry bar. The front camera of the machine is 8 million pixels, F1.9 aperture, auto focus.
Remove the motherboard process
After removing the front and rear cameras, you can remove the motherboard. The last obstacle before removing the motherboard is the coaxial cable in the lower right corner of the motherboard. The coaxial cable is removed and the motherboard can be easily taken down.
Product: Mate 9 (MHA-AL00/4GB RAM/All Netcom) Huawei Mobile Phone 4 Introduction Motherboard: Kirin 960
The motherboard is the root of the entire mobile phone, responsible for the operation of the entire mobile phone. Huawei Mate 9's motherboard design is simple, the main chip on the motherboard has a metal shield cover, the reason for this on the one hand to protect the role, on the other hand through the thermal grease connection can play a role in heat dissipation.
Main board front
The motherboard of Huawei Mate 9 can be divided into 2 parts on both sides of the camera opening. The processor part and the baseband part can be considered. The front of the left half is the power supply part of the motherboard, and the back of the left half is the processor and flash memory. The front part of the right half is the power amplifier part, and the back of the right half is the card slot and the RF part.
Back of motherboard
In order to make the phone work better, heat-dissipating silicone grease is added to the CPU for heat dissipation. The processor used by Huawei Mate 9 is the eight-core architecture of Kirin 960, 4*A73+4*A53, and the Mali G71 eight-core GPU processor, which has 180% higher performance than the previous generation graphics processor, combined with UFS2.1 high-speed flash memory. Equipped with 4GB/6GB of large-capacity storage, the running speed is extremely smooth.
Remove the widget such as the handset
Continue to remove the top microphone, distance/light sensor, and handset.
It is commendable that the Huawei Mate 9 uses an aluminum alloy roll cage. The anti-roll frame originated from the racing field. It means that the shape of a car is built inside the car through special steel pipe components. When the car suddenly suffers from external impact, the inner frame can withstand more impact, thus protecting the safety of the racer. .
Huawei Mate 9 adopts aluminum alloy roll cage, which is not common in the mobile phone market.
The earliest introduction of roll cage design into consumer electronics is high-end business notebooks. The pioneering design of this structure makes the notebook more effective against external forces, thus reducing the damage of the notebook due to accidental drops and shocks, and protecting data security. Therefore, the roll cage has become an important symbol of many high-end business notebooks.
Metal roll cages are used on smartphones. Although the roll cages can increase the strength of the products, because of the increased cost and manufacturing process difficulty, the use of the roll cage also makes it difficult to control the weight and thickness of the product. For reasons such as the comfort range, most manufacturers will not adopt the design of the roll cage, and Huawei is not easy to do this.

After the upper part of the fuselage is analyzed, continue to remove the bottom PCB motherboard, first remove all the screws. Then use a pair of tweezers to remove the metal baffle, use an insulating pry bar to pry open the connecting cable on the bottom PCB main board, and then use the tweezers to clip the bottom PCB main board. Below the bottom PCB, a vibrator is hidden, which is connected to the PCB through contacts. From the actual vibration experience, the vibrator should be a rotor vibrator.

Then disassemble the speaker, in the process, using the crowbar to try to find that the speaker is fixed very strong, in addition to the buckle, guess the bottom may have double-sided adhesive fit, decisive use of metal tweezers for disassembly. The bottom PCB motherboard partially integrates speakers, microphones, USB ports, signal antennas and other parts.

Then disassemble the battery. In the upper left corner of the battery, a piece of easy-pull tape was found. After removing the easy-pull glue, it was found that the battery could not be removed directly. At the bottom, there should be glue to fix it, and use a pry bar to pick it up slowly. After a few minutes of repeated "æ’¬, æ’¬, æ’¬", the battery was separated. Sure enough, there is a thermal asbestos sticker under the battery to fix it.
Pull out the rubber
In order to ensure daily continuous use, Huawei Mate 9 inherits the Mate series of DNA, built-in 4000mAh large battery, equipped with HUAWEI SuperCharge fast charging technology, super fast charge supports 4.5V/5A, 5V/4.5A two high specifications, maximum power Both are 22.5W. A dynamic voltage algorithm is added to this high power to automatically adjust the optimal output value instead of a fixed output value, allowing automatic monitoring of voltage, current and temperature.
Remove the battery
Compared with the common high-voltage fast charging scheme on the market, Huawei SuperCharge fast charging technology allows the charger to directly output low voltage to Mate 9, avoiding the high heat generated by the "high-voltage to low-voltage" conversion inside the fuselage, so the whole machine is charging temperature. Lower and lower heat also contribute to the increase in charging rate.
Thermal adhesive under the battery
In addition, in the actual charging process, the SuperCharge charger will automatically adjust the output voltage of the charging head from 3.5V to 5V according to the temperature of the Mate 9 chip, battery power, etc., to ensure the fuselage heat and improve the charging efficiency. In terms of charging speed, Mate 9 is only 5 minutes full of 10% power, and 58% of power is only 30 minutes, that is, waiting for coffee at the coffee shop, waiting at the station, airport In a short period of time, you can make up the amount of power used by Mate 9; it charges 5 times faster than the iPhone.
Huawei Mate 9 battery
At the same time, in terms of security, Huawei Mate 9 also has a lot of work, HUAWEI SuperCharge has five security points, in addition to SuperCharge charger, type-c connector, battery with protection points, built-in smart charging chip on the motherboard And shunt gates are used for safety protection. Each protection point has three layers of protection nets, forming 15 layers of safety protection mechanism, 5 layers of safety voltage protection network, 5 layers of safety current protection network, and 5 layers of temperature monitoring protection network. Each protection point monitors voltage, current, and temperature in real time.
Five security protections
Working together from two aspects of voltage and current, not only guarantees the safety of the charger, but also guarantees the safety of the mobile phone battery, and eliminates the safety hazard in the charging process in an all-round way. This design also guarantees the battery to the greatest extent. The service life is such that the battery is not particularly disabled after the mobile phone has been used for a period of time.
Huawei SuperCharge charging head
In the traditional charging scheme, the output voltage of the charger is constant, but the voltage of the battery is gradually rising during the charging process, so it is necessary to perform a voltage conversion in the mobile phone to adapt to the battery demand. Every time you do a voltage conversion, nearly 10% of the energy is converted into heat, so the biggest problem with the traditional fast charge program is that the phone will be severely heated when charging. Huawei's SuperCharge charger will adjust the output voltage and current according to the needs of the battery, eliminating the need for voltage conversion in the phone, reducing heat by at least 50%.
Huawei SuperCharge charging cable
In addition, before the mobile phone is charged, Huawei Mate 9 will check the type and impedance of the charging cable together with the charger. According to the carrying capacity of the charging cable, the maximum charging current is 5A, 3A or 2A to prevent abnormal heating of the charging line. The 5A data cable USB plug is assigned a purple color, and the word 5A is marked on the end of the line to prevent the user from mixing. Huawei Mate 9 supports Huawei 9V2A fast charging protocol and supports USB PD fast charging protocol.
Through this dismantling, Huawei Mate 9 not only excels in appearance and configuration, but also excels in internal structural design, with fine workmanship, firm structure, and full use of internal space. In addition, the internal heat dissipation design is equally good, in addition to the use of thermal grease and heat-dissipating stickers on the motherboard, the battery also uses a heat-dissipating asbestos sticker and cooling foam, the heat dissipation effect can be seen.
Huawei Mate 9 Family Portrait
Although many users nowadays pay more attention to mobile phone performance and system experience when purchasing mobile phones, the internal design and workmanship of the fuselage should not be underestimated. A well-designed, well-crafted product that not only extends the life of the phone, but also enhances the experience.
Whether it is charging or daily use, the security of smartphones is the first consideration. If we use mobile phones that are not quality enough, not only will the experience be poor, but security may also be threatened. It is for this reason that Huawei Mate 9 uses a low-impedance design and dynamic voltage algorithm to automatically adjust the optimal output value for fast charge safety. It also automatically monitors voltage, current and temperature through a five-layer temperature monitoring protection network. While ensuring the safety of the charger, it is also committed to ensuring the safety of the mobile phone battery. It can be said that it is a safety hazard in the charging process. All in all, Huawei Mate 9 not only has the performance flagship, but also fast-filled security is also the name of the flagship.
