High refresh rate is a great hot word in this year's mobile phone market, and the screen refresh rate becomes a critical measurement of mobile phone configuration. If the 5G mobile phone is already popular, the overall price is lowered, so how high brush + 5G does it? I explored 120 Hz iQOO Z1X internal structure. Today, let's take a look at the secrets of Oppo A92S.
The main configuration information is as shown in the figure, which is about to be disassembled as: 6GB RAM + 128GB ROM.
Dismantle
OPPO A92S uses parallel dual nano-sim cartoons, and there is no waterproof design on plastic trapping.
The rear cover is fixed using the foam, and there is a buffer camp, the upper end of the fuselage and the bottom speaker position are filled with graphite.
OPPO A92S has a rear end cap and a 20 cross-screw fixation method is used in a snap. There are 6 FPC antennas on the inside of the assembly. The rear end cover corresponds to the front and rear camera positions with the foam material for protection. There are also bubbles and dustproof nets in the speaker.
When dismantling, it is necessary to pay more attention, side key fingerprint sensor and power button together with a black plastic card on the right side of the rear shell and connected to the motherboard by the soft board.
Then, the buttons, fingerprint recognizers, power button soft plates, and rear camera protective cover on the rear end cover.
The A92S body is in the body of a conventional three-segment layout, the motherboard shield surface and the front camera on the back side of the front camera have a heat dissipation copper foil, and the rear camera is 4 independent camera components, and there is no anti-roll.
Remove the main panel connection soft board and bottom speaker, a red laminator is used for waterproof, and the semi-closed speaker module has a foam material in the outgoing hole position on the USB TYPE C data charging interface.
The battery is fitted with a double-sided viscous plastic film, which is equipped with a disassembly handle, a relatively strong viscosity, and inevitably causing a slight deformation of the battery.
Next is the dismantling of the main panel, where the headphone interface on the sub-board has a rubber dust jacket, the back surface of the motherboard, which is the same, but also has a heat-dissipating copper foil on the shield, but also a small amount of thermally conductive silicone. There is also a small PCB antenna at the bottom of the phone, and the motherboard is connected to the radio coaxial.
There are still some small components on the box that need to be dismantled, and it is very simple to dismantle it. This includes the earpiece provided by AAC Ruiji Technology, the two ECT IT radio frequency coaxial, as well as the vibrator, volume key soft plate, and speaker connection soft board.
The dismantling method of the screen will not say more, and use the heating of the bond to slowly open the bonded adhesive. On the front of the middle frame, you can see a large area graphite heat shining sticker.
E analysis
Device information
The A92S screen uses 6.57 inches of digging a full screen, and this currently dismantled is provided by Auo Au Optoelectronics, screen model: B16570122.
The front double-photography, the 6MP camera module is provided by Shugu optical production, and the sensor uses Samsung S5K3P95P.
The rear four-fitting is a separate module, of which 48MP main photographing is provided by thama technology production, and the sensor uses Sony IMX586; 8MP wide-angle lens is provided by Shuguoguang production.
The battery model used in A92S is: BLP779, and the cell is provided by ATL.
Motherboard information:
The motherboard front:
1: Media Tek-MT6873V-Tians 800 5G SOC chip
2: SK HYNIX-H9H16AECMMMD-ARKEM-EMCP 6GB memory + 128GB flash chip
3: Media tek-mt **** - Power management chip
4: TI-BQ ***** - Fast charge chip
5: qorvo- qm ***** - RF front end module chip
6: Media tek-mt **** - wifi / bt / GPS / GLONASS / FM5 combined one-piece
7: Bosch-bmi *** - Acceleration meter and gyroscope chip
Back surface of the motherboard:
1: Media tek- MT **** - Power Management Chip
2: Media tek-mt **** W-radio frequency transceiver chip
3: qorvo-qm ***** - RF front end module chip
Summarize:
OPPO A92S machine dismantles is relatively simple, and the maintenance is convenient. It belongs to the conventional three-stage layout.
A92S uses a monolithic shield in front of the motherboard, and has a large-scale heat-dissipating copper foil, and a layer of heat dissipation silicone is applied to the surface of the main chip, which can play a good heat dissipation and protection for the motherboard. There is a small radiating copper tube on the middle frame.
The rear end cap, side bond fingerprint, FPC antenna, which is common to reduce costs, and can review the IQOO Z1x receiving the previously detached iQOO Z1X also uses the same way to control costs.
Of course, it is also a major way to reduce costs in IC. You can move Ewistech to see the same price of the whole machine BOM, you can see the mystery.
Iqoo - z1x
REDMI - 10X 5G
Honor - V30 5G
Realme - RealMe X50 5G
