Xiaomi CC9 series is positioned in young people using groups, can you attract consumers? I believe that the concern of the small E is a rational consumer, let's take a look at the EWISETECH to estimate the mini cc9 of 175.8 US dollars. Ewistech has been launched in sync!
Configuration list
SOC: Qualcomm Snapdragon 710 processor 丨 10nm process
Screen: 6.39 inch AMOLED full screen 丨 resolution 2340x1080 丨 Screen 85.4%
Storage: 6GB RAM + 64GB ROM 丨 Support memory card expansion
Front: Front 32 million pixels
Rear: 48 million pixel main camera +8 million pixels wide angle camera +2 million pixel telephoto camera
Battery: 3940 mA chip ion polymer battery
Features: Back three-piece 丨 screen fingerprint
It is mainly in the camera, but the mid-end 710 is selected on the processor. Consumer groups positioned in young and favorite photos are not yet.
Dismantle
Take a look at the ewisetech engineers to evaluate the millet CC9 before telling the dismantling.
The millet CC9 is in three sections, and the whole machine is rigorous. There is a copper foil at the main board BTB interface for heat dissipation and function. The whole machine uses a waterproof design, the SIM card tank, and the earphone interface is set, and there is a certain waterproof and dustproof. There is a circle of plastic between the internal support and the screen, and the phone can play a certain buffer.
Let's go back and share the dismantling process. First take the calorie, and the calorium has a silicone ring, which has a certain waterproof and dustproof. Use the hot air gun heating the back cover and the inner support gap, heated to a certain temperature, slowly opening the rear cover, the rear cover and the inner support through the glue.
The motherboard cover and the speaker module are fixed by screws, and the NFC has a large-area graphite sheet for heat dissipation, and is fixed to the main board by gum.
The motherboard BTB interface covers copper foil for heat dissipation and is fixed, and there is a waterproof and dustproof effect at the earphone interface. The main panel and the soft board are then removed.
The battery is supported by two easy-pulled gums, and a plastic sheet is attached to the battery, and the words "prohibited dismantling" are printed, and the sensor soft plate is used with silicone ring for protection. Remove the button, vibrator, fingerprint recognition sensor and other modules.
Use the heating station to heat the screen to a certain temperature, separating the screen with the inner support. The screen is equipped with a circle in the middle of the inner support, and the phone can play a buffer when the phone falls, and the box is fixed through the rubber and the screen and the internal support.
Let us take a look at the module information!
Module information
The screen uses Samsung 6.67 "2340x1080 resolution AMOLED full screen, model Samsung AMS639WK10
(From the top down, 8 megapixel wide angle camera, model is Samsung S5K4H7, six-piece lens. 48 million pixel main camera, model Sony IMX586, six-piece lens. 2. million-scented depth camera, model is SuperPix SP2509.
Front 32 megapixel camera, model is Samsung S5kgd1, five-piece lens, and the aperture is f / 2.0.
Motherboard IC information
Finally, I naturally have to see what ICs are on the motherboard!
Motherboard reverse:
Red-TDK-EPC-D5352-Front End Module Chip
Yellow-Qualcomm-SDR660-radio frequency transceiver chip
Green -NXP-PN80T-NFC Control Chip
Cyan -qualcomm-WCD3980-WiFi / Bluetooth chip
Blue-Qualcomm-PSDM710-Qualcomm Snapdragon 710 processor
Orange -SK Hynix-H9H053AECMMD-6GB memory + 64GB flash chip
Motherboard reverse:
Red-Qalcomm-PM670L-Power Management Chip
Yellow-Qualcomm-PM670-Power Management Chip
Blue -Bosch-BMI160-six-axis acceleration sensor + gyroscope
Green-Skyworks -sky77643-31 - RF power amplifier chip
Cyan-Skyworks - Sky77925-21 - Front End Module Chip
The use of logic, memory, pm, and RF chip used on the motherboard are shown in the table:
See the table below for the MEMS chip used in the whole machine:
After reading this detailed motherboard IC information. Let me say that the main control chip is proportional, and the EWSETECH predicts the overall cost of $ 175.8, which accounts for 38.1%, about 66.86 dollars.
