Apple Watch S3 disassembly - not only can call it as simple

Apple This new smart watch can go out of independent calls and data due to joining the LTE cellular network connection, resulting in a bit unexpected hot sale, and now there is now a 3-4 week hair tip. This dismantled Apple Watch Series 3 LTE version watches (SERIES 3) should be 38mm size, although the appearance looks almost exactly the same, but in fact, the new table is new number A1889, mainly in the watch. . Series 3 is still a dismantling method of a common one-piece body mobile device. By heating the screen, then stripped the screen front panel, but this time it is necessary to be careful because the new table has more Zif soft lines. The front panel assembly section of Series 3 is roughly different from Series 2, but the IC control chip has less, and the new table also integrates multi-band antennas. The TAPTIC Engine linear motor in the watch still accounts a lot, mainly for users to vibrate reminders and force touch feedback, and the black is just a baffle. The battery is 279mAh, 3.82V, 1.07Whr, Germany from Huizhou, China, and the watch nominal life is 18 hours. You may feel that this can be used to reduce the volume of the motor, put it into a larger battery, let the watch have a longer battery life, but Apple may feel that the delicate shock will bring the experience to the user. If you don't have more Have feelings. The Force Touch component on Apple Watch is simpler than 3D touch on the iPhone, and the new features are still the same as the same paragraph on Series 2. The square below is TAPTIC Engine. Series 3 also supports maximum 50m waterproof, can wear during swimming, so the speakers are still waterproof design, and there is sound wave drainage. The new table is greatly different from the new table and Series 2 is that the motherboard is added to the RF RF chip, and there is a new air pressure height. The motherboard part of the new watch, red is the MCU ST33G1M2 32-bit MCU, with the ARM Securcore SC300 chip, which may be an ESIM card part, orange is an AV high AFEM-8057 Wi-Fi front end module (uncertain), yellow For Skyworks 78109-12 chips, etc.. Can't see S3, W2 chip? That is because these highly integrated into the motherboard PCB board. The watch cover can introduce a circular element, which is a ceramic material with a wireless charging induction coil, which is said to Series 3 compatible standard QI wireless charging, which also contains a PPG heart rate sensor. The repair factor of Apple Watch Series 3 is OK, and the line is not difficult to change the screen and the battery, but the connection of each component needs to be welded, and the S3 chip system integrates into the PCB board, and it is not easy to repair. These are places where the new table is still distressed.
