Summer is over, September is a lot of new machine has been released, then who is your idea of summer king of cost-effective mobile phone is it?
Millet official release of the Redmi K20 Pro dismantling, we look at it.
Open the back cover can see a clear three-stage structure, taken three centrally arranged opposite the upper body, the lower right side of the pop-metal cover front lens. Above the middle of the battery compartment are stacked graphite sheet heat (lower) and the NFC antenna (on). Redmi K20 Pro uses the latest generation of NXP SN100T NFC chip, speed of transactions increased by 30%.
Remove the screw pry open the upper lid, you can see the internal configuration of the main board area, the chip is left covering the heat intensive areas of graphite foil, the intermediate three camera modules, laser focus, dual flash, the right front camera is a pop-up lifting mechanical structure and the stepper motor coil. Laser aiming module after facing camera capable of fast focusing aid, millisecond laser focus allows night shooting more convenient. Laser focus assist also able to detect human faces, let Redmi K20 Pro Focus quickly and accurately when shooting portraits; it can be detected in real time ambient infrared light intensity, so that a more realistic picture of the white balance.
Redmi K20 Pro camera after three home structure, the top eight million telephoto lens enables lossless 2x optical zoom. Central 48 million Sony IMX586 camera, shooting through daily synthesis 1.6μm pixel technology quadruple the pixel super shot, effectively enhance the night view, low light conditions, the amount of light, greatly improving the quality of night scenes. 13 million ultra-wide-angle lens, 124.8 ° viewing angle large bottom, shoot shoot landscape architectural beauty of the magnificent show of shock.
Pulling the battery compartment using a quick release design, torn into two parts, can slowly pull the battery, reducing violent dismantling pose security risks at the same time easy to replace. Typical values of battery capacity 4000mAh, 15.4Wh, manufacturers of Guan Yu, Yan Wanda, even heavy use, Redmi K20 Pro can be properly the one day. 27W fast charge with high speed, 73 minutes to charge to 100%, the go go back to the blood speed.
Lifting the lower body sub-PCB cover the upper integrated 0.9cc putting large sound chamber, is connected via two contacts and the next sub-PCB. The flagship machine are very rare physical 0.9cc large cavity, so Redmi K20 Pro higher loud loudness, low-frequency deep and full.
Notably, the lower left with a small piece of the main PCB PCB RF coaxial connection, so that the block as an antenna amplifier.
A main body connected to both sides cut off, the sub-PCB RF coaxial connector fingerprint screen can tilt the sub-PCB. Can be seen that, due to the mechanical structure of the lens pop-up take up a lot of space inside, Redmi K20 Pro slot in the side of the fuselage and is not designed, and is located on the PCB sub, open bottom of the fuselage. Dual SIM card Nano-SIM card, using sealing gasket design, dust spill.
Further, the bottom USB Type-C interface with the edge of the gasket treatment effect can play a spill-life dust, the contact position of the interface with the Type-C was connected to the board dispensing process, dust corrosion .
Vice remove PCB can see from the top of the Department of Science and Technology latest generation fingerprint module screen, sensitive area increase of 100% over the previous generation, the one-shot signal amount by 40%. Further, Redmi K20 Pro in both software algorithms and unlocking experiences were targeted tuning parallel operation by the DSP, dynamically adjusting the number of fingerprint area luminance optimization, cyan gradients as flare, unlock speed detection accuracy Redmi K20 series have been improved significantly, but also significantly improved the success rate unlock at low temperatures, dry fingers, light environment and other extreme environments.
Main plate portion, front camera connector sequentially cut off, the light-sensitive panel connectors, coaxial radio frequency can then be pried motherboard, the motherboard beneath irregular foil covering a large area, the back surface layer 8 stacked graphite fins. 8 graphite can greatly enhance the ability of soaking in the horizontal direction, heat CPU allows a single point to quickly spread over the entire motherboard heat exchange with the outside world, compared to traditional single layer of graphite, to enhance the heat dissipation efficiency of 650%.
Board sides have carried out the metal shield cover opening process, the front affixed regular thermal silica, and the back surface of the thermally conductive gel is irregular, the heat shield facilitate rapid discharge of components within the housing. 8 positive graphite, thermal silica, the back heat conducting gel, graphite foil together form a three-dimensional heat-dissipation structure of Redmi K20 Pro.
Board back Qualcomm PM855 power management chip, a lens driving eject chip, high-quality high-pass WCD9340 AKM decoder chip and a Hall sensor. Hall sensor with a magnet positioned on the front camera can accurately perceive the spatial position of the camera lifting process, let down stroke more precise control.
Motherboard front Qualcomm Xiaolong 855 mobile processing platform and LPDDR4x memory stack design, the bottom for UFS 2.1 flash memory chips. Smart PA with the right large voltage Superlinear 1217 speakers and the large volume of 0.9cc sound chamber, a large volume to achieve full vigorous loud.
Board at the bottom of the screen light sensor capable of sensing external ambient light transmitted through AMOLED screen.
Pop-mechanical structure of the front lens, the stepper motor coil with drive rod connected by a front camera, the camera front sliding guides are integrally molded on the CNC by block, rail assembly accuracy than other mobile phones used by the lens pop-up higher process is more complicated.
Pre pop lens with integrated design, a more holistic, when the lens module pop-up along both sides of the wake-up lighting effect. Pop-up lens may be embedded inside the two magnets, and the Hall sensor by mating on the motherboard, so Redmi K20 Pro possible to more accurately identify the lens pop-travel position, when an external force pressing the pop-up, change the spatial position of the magnet, by Redmi K20 Pro Hall sensor detects the spatial position change of the magnet, pre-lens module quickly recover. When the pop-up lens by external shocks, springs designed to provide added buffer action.
