As the upgraded version of Xiaomi Note 2, Xiaomi Note 3 appearance looks at the relationship with the previous generation, every time, the first reaction of Xiaobian is always: "What changes will change in its interior? Complicated, is it more concise? "I prefer the latter, regardless of the experience or appearance, the internal structure of Xiaomi Note 3 should be very simple and regular. Of course, guessing is always guessing, what is the answer, but also has to take it.
Since it is as long as Xiaomi 6, then the step of dismantling is definitely no different, takes out the SIM card slot, the air gun temperature is 150 degrees, and heating is evenly heated on the back cover. It is about two or three minutes. It can be opened with the suction cup, but it is very easy. , But when you restore, you will have a headache. After all, some of the non-adhesive has been damaged, and the viscosity is also reduced. At this part, there is still a point where you need to mention the gap between Xiaomi Note 3, which is obviously more than millet 6, at least A4 paper is not going, although there is no saying that the millet is not said, it seems to Xiaomi 6 rear cover is also a number of hearts, and learned lessons and made improvements on Xiaomi Note 3. Of course, there is a reason that Xiaomi Note 3 does not support life waterproof, and it is definitely different from millet 6 in non-adhesive use.
In an instant, there are two feelings that flashed it, one is very familiar, and many millet phones, including Xiaomi 6, roughly the same; second, it feels very clean, clean, structure, but more, former, at least After most millet mobile phones, I didn't understand these colleagues who didn't understand these, I said, "Look well." This situation is also expected, on the one hand, Xiaomi is more stringent for product manufacturing control and requirements. On the other hand, as the model under the main line, the opponent OV has been doing well on the quality and workmanship, and the front of the cross cannot be more than the other.
This structure is not difficult to dismantle, according to the motherboard, panel, and battery sequence. There is a plastic baffle outside the Millet Note 3 Motherboard, which is fixed by screws and in depth to the motherboard. After removing, the motherboard also has a silver fixed screw, it is worth mentioning that the corresponding position of this screw has an arrow sign to facilitate assembly and recovery.
All connectors on the main sub-board are BTB. After removing the motherboard, all connectors are disconnected and the RF line, and the RF line of Xiaomi Note 3 is very fine, the joint fixes are also very tight, and when the demolition needs, pay attention, otherwise it is easy to damage Or take off.
About PCBs need to explain: 1, the machine panel sheet is very thin, which is probably two-half of the motherboard to one-third, which is also due to internal space considerations, reducing the thickness of the plate layer; 2, on the motherboard and the sub-board, we all discovered Compeq's logo, so you can know that Xiaomi Note 3's PCB supplier is Taiwan's Huatong, this is an old PCB manufacturer, before Xiaomi Max 2 and Xiaomi. 5C's PCB is provided by Huatong Company; 3, the motherboard is fixed very tight, even if all the screws are removed, it will cost it; 4, the vibration unit is integrated on the sound cavity, connected to the panel; 5 Xiaomi Note 3 heat dissipation is in place, the SOC portion uses double silicone fat, there is a large-area graphite heat transfer layer, while the inside of the rear cover is a large-area graphite heat transfer layer; 6, the main board integration is high, you can see numerous ICs and capacitors ;
Aspect, the motherboard shield can be disassembled to see the core chip, which labeled SEC 728 is a Samsung 64GB flash chip, not UFS 2.1, but EMMC5.1. The side labeled SDM660 is the Snapdragon 660, and the following stack has a 6GB LPDDR4X 1866MHz dual channel running memory. In fact, when seeing SoC, Kara suddenly remembered, before dismantling OPPO R11, it can be seen directly to see the processor. To be honest, remove so many mobile phones, you can see very little SOC, because in most cases, the processor will be packaged with the RAM stack, and only RAM can be seen outside. In combination with R11, the Koala Insurance should be that the Snapdragon 660 has special requirements for packaging, and at least the two 660 machines currently see are like this.
This time, a highlight of Xiaomi Note 3 is the camera, and the rear double-time can be used wide-angle + telephoto scheme, where the wide-angle lens supports four-axis optical anti-shake, from the component to directly see the optical anti-shake portion. In addition, there are more metal covers outside the double-time, which can be disassembled separately. The outer glass is actually on this metal cover, and the rear shell camera portion is empty. There is no glass, the millet 6 is put the glass behind the back cover. . The front camera is significantly higher, 16 million pixels, and the visual diameter is more than the ordinary mobile phone, supporting face recognition. The double-fitting and front camera module comes from Sunny, which is Joyu Optical Technology.
The rest is some small details:
1, Xiaomi Note 3 rear cover is very thin, but also crisp, crushing is high;
2, the bottom USB uses the Type-C interface, supports QC3.0 fast charge;
3, the battery comes from the flying leg, model BM3A, typical value 3500mAh;
4, NFC is integrated on the upper plastic protective cover on the motherboard, connected to the motherboard by contact;
5, the metal frame of the screen assembly passes through the CNC deep processing, corresponding to the area segmentation, almost all parts are reserved, and the radio frequency line slot is transversely, and the guess should be to ensure stable, so as not to sway out;
6. The intermediate IC is in the inner bottom inner bottom, which is labeled with Goodix, which comes from the metering technology, the fingerprint identification of Xiaomi Note 3 is the same as Xiaomi 6, the button is not pressed, recognition speed Fast, high accuracy, next to the fingerprint IC, screen touch IC;
7, Xiaomi Note 3 has used 4 20 screws.
Finally, it is simple to summarize a wave, after dismantling, the feeling of Xiaomi Note 3 is: the internal structure is clean and simple, there is no Huhu whistle, which is conducive to large quantity production and after-sales maintenance. Xiaomi, which is close to the appearance, the millet Note 3 has improved in multiple details, the overall performance is sufficient, the camera part is stronger than the impact force of the front Selfie, indeed the optimization routine of the offline model .
