In recent days, the attention of Huawei P30 Pro has continued to rise, from photographing the moon to being questioned about P moon (details: is the moon of Huawei P30 Pro p?), When the skeptic was fired, the great drama made netizens call it wonderful.
The above topic focuses on the "telescope" effect of Huawei P30 Pro "equipped with super sensitive Leica four cameras, supporting 50x digital zoom and built-in periscope telephoto lens".
Not much to say, ifixit, a well-known foreign maintenance team, disassembled Huawei P30 pro to see how this mobile phone achieves the "telescope" effect.
Before disassembly, let's review the configuration parameters of Huawei P30 Pro:
The fuselage is 158mm long, 73.4mm wide and 8.41mm thick;
6.47-inch OLED display with FHD + (2340 * 1080) resolution;
Eight core Huawei Qilin 980 processor, equipped with dual neural network processor and mali-g76 MP10 GPU;
8GB ram + 128GB ROM storage (up to 512gb);
Rear Leica four camera, 40 megapixel super sensitive camera (wide angle, f / 1.6 aperture, OIS) + 20 megapixel super wide angle camera (F / 2.2 aperture) + 8 megapixel super zoom camera (F / 3.4 aperture, OIS) + Huawei time of flight (TOF) camera;
A new earphone speaker technology called "acoustic display technology" and a display fingerprint sensor;
Usb-c charging port (but no headphone jack);
IP68 waterproof / dustproof grade
More integrated appearance
Compared with the previous P-Series flagship Huawei P20 professional, the P30 Pro is 3mm higher, 0.61mm thick and 0.5mm wide than the previous one, but the weight is less than 15g.
In terms of appearance, the P30 Pro screen has a larger display range because it deletes the entity home key; At the same time, the left and right sides of the fuselage are designed with curved surfaces, making the hand feel more slender and thin. Behind the fuselage is the logo of P30 series - Leica four photos. The rear fingerprint identification has also been replaced by off-screen fingerprint identification technology, which makes the whole machine more integrated.
Along the bottom edge of the phone, we can see that the usb-c port still exists, and the two symmetrical speakers have been cut in half, leaving four microphone holes, mainly to make room for the SIM card slot.
Fuselage fixed with a lot of glue
Ifixit said that the whole disassembly process of P30 Pro is difficult, because the gap between the body frame and the rear glass is very close, and a large amount of glue is used to fix it, so the gap can hardly be seen by the naked eye.
However, these glues provide Huawei P30 pro with IP68 waterproof and dustproof standards. The back cover of the fuselage is made of glass, making wireless charging possible.
After opening the fuselage, you can see that the internal space layout of P30 Pro is very compact and reasonable. It can be disassembled with only a cross screwdriver.
Wireless charging coil
The first thing that comes into view is the wireless charging coil. It is connected to the motherboard, with some antennas and an orange flexible cable for connecting two contacts.
This charging coil not only supports wireless charging of mobile phone, but also reversely charges mouse, electric razor or toothbrush.
It seems that reverse charging is becoming one of the standard configurations of 2019 flagship mobile phones.
Beautiful optical technology
With the P30 Pro fully turned on, we went straight to the camera. The first is the new periscope camera module, which is said to achieve 50x zoom.
Interestingly, the module does not protrude like other cameras, but rotates 90 ° from the aperture and is placed flat in the mobile phone. The prism refracts the light onto the sensor.
Overall, the P30 Pro has five cameras. There are four rear cameras on the left, from top to bottom: 16mp ultra wide-angle lens (F / 2.2 aperture), 40mp wide-angle lens (F / 1.8 aperture), 8mp long-range lens (F / 2.4 aperture, OIS) next to it, and periscope camera module at the bottom. The front camera is a 32 MP, f / 2.0 aperture single lens on the right.
pcb
After the camera module was removed, we saw the most critical PCB motherboard.
In terms of shape, the circuit board of P30 Pro is very irregular. The largest hollow in the middle is the position of the camera module, accounting for nearly one third of the board space.
The circuit on the whole PCB is very compact, showing a state of multiple stacks. Ifixit guessed that this motherboard is most likely a high-rise multi-layer PCB or a stacked design, that is, two PCBs are stacked together.
In order to further understand the information of the motherboard, let's look at the core components on the PCB one by one.
The first is the front of the motherboard. The orange one is Meguiar jz064 mtfc128gaoanam-wt 128 GB flash memory; The red one is skhynix h9hknnnfbmau lpddr4x memory, which is stacked above Huawei Kirin 980 processor through pop process; The yellow one is Hisilicon hi6405.
The second is the reverse side of the motherboard. The green one is Hisilicon hi6363 gfcv100 RF transceiver; Sky blue is the front-end module of skyworks 78191-11 for WCDMA / LTE; The dark blue is the qorvo 77031 front end module.
Screen speaker
From banged screen to dripping screen and Pearl screen, the key is how to deal with the traditional front earpiece. P30 series adopts "screen sound technology", which embeds the vibrating speaker module into the mobile phone to reduce the space of "bangs" on the screen.
This is almost like an "ordinary" speaker, but it does not generate sound waves by vibrating the diaphragm, but through vibrating the rigid surface (glass screen), which is equivalent to converting the screen into a speaker.
The driving part of the module includes a coil with a magnet in the middle, which is connected with the part of the vibrating screen, and the screen is adhered to the back of the display.
Components at the bottom of the fuselage
Next is the type C interface and the cables connected to it. If you choose to use wireless charging, I believe the wear of type C interface should be greatly reduced.
It is separate from the daughter board and SIM card reader.
The traditional speaker module at the bottom is also extracted.
Off screen fingerprint sensor
Finally, the Chinese people are proud of the off-screen fingerprint sensor, which is installed near the bottom edge of the mobile phone. It is GOODIX gm185 from huiding technology.
GOODIX gm185 has been used in one plus 6T, Xiaomi 9 and vivo nex s. It can be seen that the off-screen fingerprint identification function has also become one of the standard configurations in domestic high-end flagship machines.
Battery
In terms of battery, there is a convenient pull ring next to it, which continues the design of mate 20 pro.
This battery has a capacity of 16.04wh (4200mah, 3.82v), which is equivalent to mate20 pro, and beats 15.79 wh of Galaxy S10 +, not to mention 12.08 wh of iPhone XS max.
screen
After separating the screen, we can see that another part of the screen sound module is tightly bonded to the back of the screen.
Similar to the back cover, the gap between the frame and the display is almost invisible to the naked eye. Ifixit is very sure that this display is completed after heating, cutting and prying.
"The strong adhesive line between the frame and the display is against us like spider man trying to reassemble the ship." Ifixit said humorously.
At the same time, they are very worried about whether the "screen sound technology" speakers bonded to the screen will have problems such as sound distortion and failure to operate when the screen is broken or damaged.
To sum up, the internal structure of Huawei P30 Pro is more compact, especially the bonding between core devices, PCB customization and a large number of glue fixation, which has greatly improved the internal and external integration of the whole mobile phone.
As a high-end flagship machine focusing on "future photography" technology, the four camera modules of P30 Pro are distributed in a disordered manner, and the design is not disordered due to the increase in the number of modules.
Finally, ifixit gives a repairable score of 4 points (the total score is 10 points. The higher the score, the easier it is to repair).
