The glory 50 series is the first digital series after the independence of glory. It is impossible to face the difficulties that the glory 50 series is successful, which also proves that the appearance of glory is still there. Dissolving the glory of the unicorn chip 50, which is also inevitable for ewistech. So what kind of answer will be given to everyone after the high sales of the glory 50 series after dismantling?
This dismantling is the 8GB + 128GB version. The dismantling equipment is purchased from the e-commerce platform, and the dismantling analysis content is based on the device.
E dismantles
Take out the Carto, and there is a silicone ring on the calvator. The rear cover is fixed by a hot air gun, and then opens the back cover with the suction cup and the cladder. The NFC coil position in the back cover is attached to the graphite sheet for heat dissipation. The camera cover is secured to the back cover, and the front is posted with a bubbles for the lens.
The top motherboard cover and the bottom speaker are fixed by screws. There is a graphite film on the motherboard cover and speakers, and the graphite sheets extend to the battery position, which is conducive to heat dissipation. The motherboard cover has adhesive NFC coils, flashlights. Remove the shrapnel plate on the speaker. Note that the rear camera module has a plastic frame fixation.
Remove the motherboard, panel, front and rear camera modules and coaxial lines. The motherboard front processor & memory location is applied with heat dissipation silicone for heat dissipation, and silicone sets are still set to have a silica gel in the USB interface.
The battery is fixed by plastic tape. Demand according to the pull of the pull handle. Then remove the button soft plate, the sensor board, the main sub-board connection soft board, the earpiece, and the fingerprint recognition sensor soft board.
6.57 inches of Wusin OLED screen and the inner support pass the glue, the adhesive area is large, the heating screen is opened, and the screen is opened by the cladding and suction cup. There is a large-area graphite sheet on the front side, and the liquid cold tube is not found.

Demolition summary:
Glory 50 The whole machine uses 23 screws to fix, using a relatively common three-stage structure. Medium dismantling is medium, reducing reducing. The SIM Cardo and USB interface are protected by silica gel, which can play a certain dustproof. The whole machine uses heat-conductive silica-graphite to heat dissipation, and no liquid cooling pipe is found, which is lacking in heat dissipation.
E analysis:
E Analysis Bar At present, with the arrival of the 5G era, more and more domestic chip vendors have broken the overseas situation. In the glory of the unicorn chip, what kind of domestic chips can we find? First take a look at the IC marked by the motherboard.
The main IC of the motherboard:
1: QUALCOMM-QPM5541-RF amplifier chip
2: QUALCOMM-QPM5577-radio frequency amplifier chip
3: TI-BQ25970- fast charge chip
4: QUALCOMM-WCD9370-audio codec chip
5: QUALCOMM-SM7325-Qualcomm Snapdragon 778G processor chip
6: MICRON-8GB memory + 128GB flash memory chip
7: QUALCOMM-PM7325B-Power Management Chip
8: QUALCOMM-WCN6750-WiFi / BT chip
The main IC on the back of the motherboard:
1: NXP-SN100T-NFC control chip
2: QUALCOMM-PM7350C-Power Management Chip
3: QUALCOMM- PM7325-Power Management Chip
4: QUALCOMM-SDR735-radio frequency transceiver chip
5: QUALCOMM- QDM3301-radio front end module chip
6: QUALCOMM-QFM2340-radio front end module core
7: Onmicro-OM9902-11-RF amplifier chip
8: Onmicro-OM9901-11-RF amplifier chip
With the motherboard, we can find that this glory 50 can not use the unicorn chip. In addition to the high pass with the processor, there are two radiofrequency amplifier chips from domestic manufacturers of Angui Micro, OM9902-11.
OM9901-11 is 2G band design, low frequency bands support GSM850 / EGSM900, high-frequency segment supports DCS1800 / PCS1900 band. OM9902-11 supports 3G / 4G / 5G NR band.
This is the first time EWSETECH engineer found the manufacturer's chip, OM9901 and OM9902 were the 5G sub-3GHz Phase5N solution launched in 2020 in 2020. Angi is a complete PA / FEM product line series with a full range of 2G, 3G, 4G, 5G Phase5N, L-Pamid, and L-Pamif. And the first manufacturer of CMOS PAs and GaaS PA technology in China with large-scale mass production.
At the end of 2020, Angui's Phase5N RF front-end module has achieved mass production in a number of mobile phone manufacturers and ODM programers. And this glory 50 is used, it is the first time, the first time I entered the glory supply chain. Domestic manufacturers are available for glory 50, and they have also proved their strength from the side.
