Glory V40 as the first flagship machine in the independent glory, because all the reasons are finally equipped with the Lianfa Tianzhu 1000+ processor, Xiao E does not be curious, lose the unicorn processor, then the V40 also uses the Haisi chip in the V40? To solve the problem, you must purchase a dismantling.
The glory V40 of this purchase is 8GB RAM + 128GB ROM version, which is dominated by disassembly analysis in the paper.
Note: The cost is only for material cost estimates, and there are many factors affecting the cost of components, and there is a certain difference in real material costs.
Dismantle
Shutdown to take out the calorker with waterproof silicone ring. The rear cover is fixed by the adhesive, and after heating through the hot air gun, the rear cover is opened by the suction cup and the cladder. The rear cover corresponds to the battery position and the inside of the rear lens cover, which is attached to the protective bubble.
The top motherboard cover and the bottom speaker are fixed by screws. The main board and a large-scale graphite sheet on the speaker can be used to heat dissipation. There is also a flash soft board BTB interface protected by a metal cover.
Remove the NFC coils on the motherboard cover, flashlight soft board and microphone board. The liquid cold tube is attached to the motherboard cover corresponding to the NFC coil and the power supply area on the motherboard.
Remove the motherboard, sub-board and front and rear camera modules. The thermally conductive silicon fat is applied to the main board processor & memory chip position. Sub-board USB interface has a silicone ring for waterproof.
The battery is fixed by plastic tape, easy to disassemble.
Remove the button soft plate, handset, fingerprint identification soft board, vibrator, etc. supported by the adhesive.
The V40 screen is fixed by the inner support, and finally the screen is separated after heating the heating table. The inner support positive surface is laminated, and the graphite sheet is a liquid cold tube.
Retrospecting the entire machine dismantling process, a total of 20 screws are used to use a relatively common three-stage structure. Demolition is simple, reducible. Waterproofing Web interface, SIM Cardo and speakers are protected by silica gel, which can play a certain dust-proof waterproof. Heat heat pipe + thermally conductive silica fat + graphite sheet is performed. Not only in the large-scale liquid cooling pipe, the motherboard cover is also attached to a small area of liquid cold tubes.
E analysis
After dismantling, the whole unit of glory V40 is organized. In 1472 components of the whole machine, there are 190 in China, accounting for approximately 12.9%, accounting for approximately 59.5% in the cost of materials. So why is it as high as it? First, in some major components, such as screens, V40 is selected is 6.72 inches in the East, and the model is BF067DYM, and the cost is second only to the processor chip.
Be
Of course, the main still is the IC, and the Tianzhu 1000+, which must be the top of the component cost. So in addition to the processor, let's take a look at the glory V40 which domestic chips.
The main IC of the motherboard:
VANCHIP-VC **** - RF amplifier chip
NXP-PN *** - NFC control chip
SanDisk-SdineDK4-128G-128GB flash chip
SK HYNIX-H9HKNNNFBMAV-8GB memory chip
Media TEK-MT6885Z69- 天玑 1000+ processor chip
Media tek-mt **** PP-power management chip
Lansus Technologies-FX5566-RF amplifier chip
Hisilicon-Hi6526-power management chip
Media tek-mt **** - wifi / bt chip
The main IC on the back of the motherboard (below):
Media tek-mt **** V-power management chip
Media tek- MT **** QP-power management chip
Media tek-mt **** rp-power management chip
STMicroelectronics-six-axis acceleration sensor + gyroscope chip
MURATA-Power amplifier
Media tek- MT * W-RF transceiver chip
Murata-multiple modulator chip
Murata-multiple modulator chip
Hisilicon-Hi6D05-power amplifier chip
After the IC BOM of the integrated machine, it was found that the proportion of V40's domestic chip also increased, and the supporting chip of the United Kingdom, and two Haisi chips. Even we have found a radio frequency amplifier chip from Shenzhen Feizhong Technology. Of course, this is only part of the whole machine analysis, and the complete BOM is currently on the EWSETECS search. Remember to see it!
