Also configure, it is necessary to have a low price, how is the new standard REDMI9 of the entry machine of 2020?
In June, the red rice released a REDMI9. The price is 799, and it is known as the new standard for entry in 2020. Today, let's take a look at what REDMI9 has passed the standard.
Dismantlement step
Still old, use the card to take the card, and the calorie has a waterproof rubber ring.
RedMI 9 uses a plastic back cover, and is only secured between the fuselage. You can slowly slowly along the gap from the position of the Carto, remove the back cover. The rear cover protects the glass position on the motherboard camera, posted a lap fixed glue.
The 许 is for cost considerations. The main antennas and WiFi Bluetooth antennas are used to secure the FPC antenna that is fixed on the back cover.
The motherboard cover and speaker modules are supported by the screws, and there is a screw with a slim tag on the upper and lower, respectively.
Both the motherboard cover and the speaker module are fixed by screws, and the BTB port of the motherboard connection soft plate also has a metal sheet with a screw and a buffered wool. The speaker module poses a conductive bubble and waterproof label on the front of the speaker module, as well as a graphite heat exchanger that extends to the battery.
The handset soft board and the fingerprint identification module are fixed on the motherboard.
In particular, there is a separate camera protection cover under the motherboard to protect the fixed camera module. There is also a bubble in the BTB connector portion to buffer.
After the motherboard is removed, there is a thermally conductive silicone on the shield of the main chip position, and there is a conductive bubble in the position of the frame. Sub-board USB interfaces and earphone holes are covered with silica gel case.
In the middle frame below the motherboard, there is a single light / distance sensor soft plate.
Battery use two easy-pull gelatin to make it easy to replace the battery. The battery will also be deformed after the battery is removed. Removing the light / distance sensor also has silicone sleeves to protect.
Finally, the screen is heated. The screen is the LCD water dripping screen, and does not see the touch chip, it should be integrated in the screen. A large area of graphite heat is supported in the front side.

Tianma's 6.53 inches, resolution 2340 x 1080 of the LCD water dripping screen.
The front choice is Samsung, the model is the 8MP camera of SSK4H7YX.
13MP main photo, model is OV757EA, 8MP super wide angle, model is Samsung S5K4H7YX. There is also a 5MP macro lens + 2MP depth of field shots.

The main IC of the motherboard (below):
1: Media Tek - MT6769V / CT - Barn processor
2: Samsung - KMDP6001DA - 4GB Memory + 64GB Flash
3: VANCHIP - RF power amplification module
4: AKM - electronic compass
The main IC on the back of the motherboard (below):
1: Media Tek - WiFi / BT chip
2: Media TEK - Power Management Chip
3: Microphone
4: Media TEK - RF transceiver
5: VANCHIP - RF power amplifier
Summary information
The difficulty of the whole machine is not difficult. It can be done with better reducing and easy to repair. There are two screws on the 19 screws of the whole machine, which are located on the motherboard and the speaker module. The whole machine has two waterproof labels, and the battery is easy to replace.
Due to the price of the price, the whole machine will inevitably compress. This can be seen in the selection of hardware such as chips and screens. In addition, only the card buckle is used to secure the rear cover, and the selection of the FPC antenna. It is also a selection option for cost control.
There are also these devices in the ewisetech search, etc., you are waiting for you ...
