In the wonderful KPL Autumn Finals last year, the new generation of KPL official game machine iQOO7 is also unveiled at the event. As a non-professional game mobile phone, why can it become the official game of KPL? If only from the basic configuration, it may be too shallow. ewisetech is of course a good to disassemble it.
120W is charged, is it only upgraded?
ATL's 3890mAH lithium polymer battery weight reached 64.6g, which was more important than the general battery. The battery selects the dual-core design, which uses the MTW array extreme ear structure. There is a very ears in each of the windings, which greatly reduces the internal resistance, and the feed is controlled from the source to control the heat generation.
In order to meet the 120W ultra-fast flashing charge of iQOO7, a charge pump chip (BQ25980) of Texas Instruments, and 1 BQ25790 5A four-cell switch mode buck-boost battery charging chip.
In order to support heat generation of 120W charge, the large area of the large area of the hot plate in IQOO7 has 4096mm2, and the internal structure + fiber power pump design can accelerate the internal liquid circulation, and the heat is dispersed to strengthen the heat dissipation effect.

Now I will return to the dismantling to see the interior of this phone.
Shutdown to remove the calorie, the calorie has a silicone ring to dustproof and waterproof.
The adhesiveness of the rear cover is not strong, and the hot air gun is heated to 200 degrees, and the tab is opened. The middle of the rear cover is positive to the battery position to a buffer.
Unscrew the screw and remove the top motherboard cover and the bottom speaker module. The motherboard cover and the speaker are laminated on the speakers, and the graphite sheets cover the motherboard, batteries and sub-plates.
BTB and camera positions are posted on the main board, and 2 FPC antennas are also integrated on the motherboard cover.
Remove the motherboard, panel, main panel connection soft board and front and rear cameras. It can be seen at the USB Type-C interface at the bottom of the weapon to dustproof.
Be
The motherboard is designed with a double sheet design, and the main board BTB is posted on a bubble or silicone ring protection.
Be
Both the front and reverse surface of the motherboard are disconnected, and there is a thermally conductive silicone in both the shield at the main chip position.
The battery is fixed to the two sides, and each of the battery has a BTB interface, which can act as a heat transfer.
There are two vibrators, and the two pressure lines are fixed by glue; the handset, fingerprint identification module and screen connection cable are fixed by glue, and the side key soft plates are supported by the plastic card. There is a red silicone ring in the bottom microphone and speaker position to dustproof.
Be
The FPC antenna is used in the top position of the internal support.
Be
Finally, the screen and inner support are separated by the heating table, and the large area of the hot plate between the two can be taken, and the large-scale graphite sheet is posted on the hot plate.
Be
The screen is selected is a Samsung 6.62 inches, 2400x1080 resolution AMOLED screen.

Disassemble summary
The whole machine uses three-segment design, with a total of 19 screws for fixing. Although IQOO7 does not support waterproof, some waterproof processing is performed internally, and there are silica gel protected in the opening position. Since IQOO7 supports 120W fast charge, the heat generation is large, so there is a lot of effort, 4096mm2 super average hot plate + copper foil + large quantity of stone ink is dissipated in heat dissipation.

Module detail
The control realizes the compactment function of 2 screens, and the pressure control chip of core sea technology is completed.
Before shooting into Samsung S5K3P9, 16 million pixel camera, aperture F2.0.
The rear three-student is Sony IMX598, 48 million pixels ultra-clear main photos; Samsung S5K3L6, 13 million pixel super wide angle camera; Samsung S5K3L613 million pixel portraits.

Summary information
The Qualcomm Snapdragon 888 processor used Qualcomm Snapdragon 888 is used in the previous millet 11 and Samsung Galaxy S21, and a double board design is used. It seems that the flagship series processor still requires a double-layer design to save space to facilitate more devices.
So you pay attention to the game, you will choose this 2021 king's glory KPL Spring Festival official game machine, is it your own upholi? (: JUDY)
