When it is issued, the lowest price 5G mobile phone should be Realme V3, the price is 999. Second, Realme V5 and RedMi K30i, priced at 1499. More than a year, 5G mobile phones have been so low. 1499 RealMe V5 We naturally have not missed, let's take a look at how V5 controls costs.
Regarding the reasons for 5G mobile phone price reduction, it can be seen in the previous time. "E analysis: I have disassembled so many 5G mobile phones, I found 5G mobile phone price reduction. ".
Dismantle
First remove the calorie, and there is no film waterproof on the calorie.
The rear cover is fixed using black adhesive, heating the back cover with a hot air gun, slowly open.
The inside of the rear cover has a foam for filling the gap between the rear cover and the battery. There is a graphite film on the speaker position and the battery, and the upper motherboard position is plastic sheet.
The camera protective cover is fixed with a black adhesive between the body, and uses the crowbar to take a bubble.
In the middle frame, the inner support is fixed by the card slot and screws, and after unscrew the screw, use the crowbar along the snap, slowly open the box. There are graphite cooling stickers and PFC antennas. The flash soft board is also pasted on the middle box.
After removing the middle box, the disconnect-side key fingerprint sensor is connected to the BTB interface, you can remove, the fingerprint sensor has a silica gel in the back of the fingerprint. It is also possible to see a waterproof label on the motherboard, and copper foil is also dissipated on the motherboard shield.
Next, remove the screw fixing speaker, and the plastic film fixed battery. The speaker module is connected to the panel with a panel, and a waterproof label is also attached to the sub-board.
Remove the motherboard, panel, main panel connection soft board, power button soft plate, coaxial, and front-rear camera.
The back of the rear camera module has a conductive tap, and the front camera module is a copper foil.
Silicone envelopes are protected from the AUDIO JACK interface and USB of the sub-board.
Remove the handset, side key soft board, speaker connection soft board and vibrator. In the speaker, there is a fixation on the soft plate, and the waterproof label is posted below the internal support.
Finally dismantling the screen, there is a large-area graphite tile under the screen, and there is a protective tape protection, and there is a large-area granular heat sink side on the side of the support bonding screen, and four conductive cloth is attached to the inner support.
RealMe V5 machine uses 19 screws, and the overall dismantling is not difficult. Three-stage internal design, although there is no waterproof ring on the calorie, but there is three waterproof labels internally. The heat dissipation method is also a conventional thermally conductive silicone-copper foil + graphite sheet for heat dissipation, and no liquid cooling is provided. The antenna is used is an FPC antenna, which is conducive to control costs.

RealMe V5 machine IC is naturally more than this, and the entire machine BOM can be queried in ewistech. The 1155 component analysis of the disassembly is compiled, the overall assembly cost is approximately 149 $, in which the main control IC part occupies 58.8% of the total cost. From the component unit price TOP 5, it is also possible to intuitively discover the Liaotai Tianzhu 720 processor, which is the first element of its control cost.
In addition, the small partner also founds what control costs, don't worry about your discovery!
