Smartphone is not a new thing in shooting. In order to break through hardware restrictions, all major mobile phone manufacturers have taken the backbound camera and even more cameras. In terms of multi-camera, Samsung's Galaxy A9S released at the end of last year is a fast person and adopts the designs of the back. This time, I will bring you a dismantling of Samsung Galaxy A9S. How do you put four "stuff" into your mobile phone.
Decomposition highlight:
Rear four cameras
The motherboard is not a "7" glyph or "U" type of Samsung.
SIM card slot reserves storage card extension

Samsung Galaxy A9S BOM Table:
Samsung Galaxy A9S 6GB + 128GB national line is priced at RMB 3499.
As can be seen from the BOM table, since the screen is Samsung's own products, the power management chip for the screen is only provided by Samsung "." So the main components of Galaxy A9S, in addition to the memory chip, most of them come from Qualcomm.
The memory chip occupies nearly 29% of the overspeed price, which has become the highest cost of Galaxy A9S. This memory has a high price. In addition to its own 6GB + 128GB of storage space, it is also reflected in its process level.
Memory and flash memory are not simple stacking, which use Samsung unique chip stacking techniques such that the thickness of the entire chip can be further compressed.
At the same time, Samsung also uses its own expertise in the MCP mobile DRAM and NAND components, so that this series of memory chips can have higher yields, ensuring stability of their supply.

Detailed dismantling:
Remove SIM Carto, Samsung Galaxy A9S SIM Carto uses a dual card + memory card extension design, and the memory card supports 512GB extension, and Touro has a waterproof rubber ring.
Heat the back cover edge of the phone with a hot air gun to 80 ° C, and then open it with a crowder. The rear cover is fixed by the white strip, although Galaxy A9S uses a rear fingerprint design, but the fingerprint recognition module is not designed on the back cover, so there is no part on the back cover when the rear cover is opened. The fixed / protective cover of the rear four-piece can be taken directly below the rear cover.
The middle frame and the inner support are fixed by a screw. The fingerprint recognition module is fixed between the middle frame and the inner support, and the fingerprint recognition module provides a fixed groove on the frame.
In addition to the fingerprint recognition module, there is also a NFC coil and some buttons on the side. Where NFC coils are fixed in the middle frame, the NFC coil is attached to the motherboard.
The main board and the sub-board are connected by a cable, and the battery can be removed after the cable is removed. The battery is fixed to the body by two double-sided gums.
Remove the motherboard, panel, and front and rear camera modules. The main heat generation of the motherboard processor, flash memory chip, circuit protection chip is supported, and the back camera module is fixed to the motherboard by double-sided adhesive modules.
Finally, the screen is separated from the internal support, and the screen side is heated, and the screen and the inner support are fixed through the double-sided adhesive on the black glue and the screen backplane, so simply add the screen to 80 ° C. The two can be separated.

Perhaps it is necessary to retain enough position to place the four-piece relationship, Samsung Galaxy A9S motherboard design can be said to be a model of "the least Samsung" in recent years. The motherboard does not use Samsung's common "7" glyph or "U" design, but uses a more square design. In order to control the volume of the mobile phone, add the four-fitting camera module, so that the arrangement of the main board is relatively compact.

Rear four more detailed explanation:
Samsung Galaxy A9S adopted a back four-piece design, and the rear four-fitted is integrated into a module. However, although it is a module, each camera is still connected to the motherboard with the respective separate soft boards.
According to the top and down the top, the camera is wide-angle camera, telephoto camera, main camera, respectively, and a prominent camera.
The wide-angle camera is 8 million pixels, the perspective is 120 °, the model is Samsung S5K4hayx.
The telephoto camera is 10 million pixels, the model is Samsung S5K3M35M.
The main camera is 24 million pixels, supports OIS anti-shake, provided by Sony.
The promised camera is 5 million pixels, the model is Samsung S5K5E9YX, which does not participate in direct imaging.
The front camera is 24 million pixels, the aperture is F2.3, which is also provided by Sony.

Disclosure rating:
Summarize:
The rear quadrupleness is undoubtedly a big highlight of Samsung Galaxy A9S, but by disassembling, the bigger highlight of the machine may become a Samsung mobile phone that has been "the most unlike Samsung" in recent years.
The middle frame of Samsung Galaxy A9S and the main secondary shield "Connected" is also a highlight of the Galaxy A9S internal structure. The main purpose of this design is to make each component inside each component is better fixed and protected.
In addition, Galaxy A9S's motherboard is changed to Samsung's previously used "7" glyph or "U" design, which adopts more square processing, such design, may be space placed in the next four times, and On the one hand, it may be more space for the battery, after all, in a mid-range, 3720mAh, a battery is not common for mid-range models of foreign manufacturers.
