iqoo's Z series is iQOO has a product line. The first Z1 chose the 1000PLUS processor equipped with MTK. IQOO Z1X chose Qualcomm Snapdragon 765G processor, the price is also nearly 400 yuan. In addition to the IC's choice, what places in the interior controlled costs? Let's take a look.
Dismantlement step
First of all, first use the card needle to remove the calorie, and there is a silicone sleeve for dustproof. The rear cover is fixed by the adhesive, and it is necessary to take it by heating.
The rear end cover is fixed by screws and buckles. The fingerprint recognition module is fixed to the rear end cover.
In addition, the rear end covered a circle of FPC boards, together with 4 FPC antennas. And posted a lap in the edge of the foam protection. Battery warehouse has also been used for foam protection.
When removing the motherboard cover, it was found that the flash soft plate and the canapper soft plate were fixed to the motherboard through the gum, and the vibrator was fixed on the speaker module.
The battery is fixed through the entire plastic paper, and the side is easy to replace the battery.
Remove the motherboard, panel, radio frequency coaxial and front and rear cameras. The radio frequency coaxial is fixed to the groove next to the battery, and the earphone hole and the USB TYPE-C interface are protected by silica gel.
The soft board, handset, and side key soft plates are connected to the main panel.
Finally, the screen and internal support are separated by heating, and the heat conductive copper tube is removed. There is no touch chip on the screen, it should be integrated on the screen. The heat dissipation copper pipe is fixed to the middle frame, and there is a layer of graphite between the screen.
Module information
The screen is a TFT screen with a 6.57 inches 2408x1080 resolution. 120Hz refresh rate.
The 16MP pre-model is Samsung S5K3P9.
The rear 2MP macro + 48MP main photo + 2MP portrait depth of field camera, where the main model is Samsung S5kgm1.
The battery uses a 4880mAH lithium polymer battery with a Samsung cell.
Dismantling analysis
IQOO Z1X is used for 20 screws. The SIM calorker and the USB interface, the earphone bore is dust-proof, and the internal heat is reduced by graphite sheet + heat-conductive silicone-copper foil + liquid cold copper tube. Due to multiple glue fixation in the whole machine. Therefore, the dismantling is relatively simple, but the glue on some parts is not easy to recover.
Motherboard information
When taking the screen shield, we see a large heat-dissipating copper foil at the CPU location and coated with a thermally conductive silicone. After the copper foil is removed, heat-conducting silicone is also coated on the main IC.
Also, the bare devices on the motherboard and the sub-plate are protected by dispensing.
The main IC of the motherboard (below):
1: QUALCOMM- SM7250-Qualcomm Snapdron Bar Nucleus Processor
2: SK HYNIX- H9HQ53AECMMD-6GB memory + 64GB flash memory
3: QUALCOMM- WIFI / BT chip
4: QUALCOMM-power amplifier
5: QUALCOMM-audio decoding chip
6: Bosch-gyroscope + accelerometer
The main IC on the back of the motherboard (below):
1: QUALCOMM-RF transceiver chip
2: qorvo - front-end module chip
3: QUALCOMM-Power Management Chip
4: Goertek-Microphone
Summary information
The use of the rear end cover is rarely used today. And the FPC antenna in the phone is integrated on the rear end cover, which is also uncommon, but this design is relatively lower. In addition, in order to control the cost, the screen is selected is a TFT screen of Tianma. Fingerprint recognition is also transit into a relatively inexpensive side fingerprint recognition.
In addition to reducing costs on some devices, the processor also chooses Qualcomm Snapdragon 765g, not the previous Tianzhu 1000Plus processor. That specific part price, in the ewistech searchak list.
