After entering 2014, the entire mobile phone market can be said that the era of the peak of the international big-name occupation industry has gradually passed, and more mobile phone brands are sealing the strongest smartphone, regardless of the design or hardware configuration or UI. Both fights, the war has reached the stage of white heat.
In fact, for the majority of consumers, hardware configuration and system experience is far from the quality of mobile phone itself, and is durable is the just need for people to mobile phones. As a popular thermal machine currently released, Sony Z2 can be described as an eye of consumers, powerful hardware configurations, and practical three-proof performance are one of its biggest selling points. So do you have any mobile phones that don't have weakness, whether the internal work is strong? Let us know the answer by dismantling.
Sony Z2 front design
Let's take a look at the overall appearance of Sony Z2 before disassembling the machine. From the shape of the shape, Sony Z2 did not change significantly before it was compared. It is still the familiar body and the familiar button layout, but the screen has increased to 5.2 inches, and uses IPS screens, this is A breakthrough in the Sony series mobile phone.
Sony Z2 Rear Design
In terms of back design, Sony Z2 still uses a glass textured rear shell design. It has a 20.7 million-pixel lens back, and the camera is very good, and the camera function is also very powerful. In short, it is the insufficient innovation of Sony Z2 modeling, but it is still possible to accept consumers. Introduction, let us enter the official disassembly of Sony Z2 together.
Removers from the back shell
For Sony Z2, choose where to disassemble, it is heavy. From this experience in Sony Z1, the glass textured back shell is our home, and you need to use a very thin iron piece to gently dial the adhesive, then slowly pick it up with the edge.
Pathogenicity
The operation is very patient, after all, Sony Z2 is a three anti-mobile phone, so the righteous seam of the back shell is necessary, but though, after our effort, it is still successfully opened the back shell of Sony Z2.
Successfully completed separation
After opening the rear cover, we have no doubt out of the Sony Z2 battery and motherboard. Among them, the motherboard chip has been hurt by the metal shield, and the battery has also packaged a yellow tape. Overall gives a very strict feeling.
Backplane is very thin
The picture shows the back panel of Sony Z2. From this perspective, this glass textured panel is really thin.
Motherboard
The picture shows the strict motherboard close-up of Sony Z2 by metal shielding cover.
Battery under construction
Under the bottom of the battery, there is a speaker and a vibrator of Sony Z2.
See the screws
From the figure I just saw, the Sony Z2 of the motherboard and battery area Sony Z2 is fixed. If you want to know more about this phone, you have to take all these screws.
Remove six screws
Since the screws on the Sony Z2 fuselage are cross-type design, we can easily find the corresponding screwdriver. The figure is the six screws taken down.
Remove 3200mAh batteries
We know that important first is to disconnect the power. Sony we have removed the screws, the first thing is to take the battery. From the figure we can see that the capacity of Sony Z2 is 3200mAh, which is more than enough to meet everyday use.
All disconnected
After taking the screw and the battery, we also need to disconnect all the currently disconnected parts, interfaces, cables, etc. This will ensure that the phone will not affect the phone when disassembling the motherboard.
Take down parts
Figure is a rear camera that is removed and Sony Z2. This Sony Z2 is still a 20.0 million pixel G lens, and the camera effect is very good.
Rear view of the main board of Sony Z2
The picture shows the back view of the main board of Sony Z2 (relative to the mobile phone). We can see that this motherboard is mainly a metal shield covered, which also shows that the chip here is more.
There are still many parts on the screen panel
After removing the motherboard, we can reveal the Sony Z2 screen panel. From the figure we can see that Sony Z2's handset and headphone jack are inlaid here.
Vibrators and speakers
We have already mentioned that below the Sony Z2 is its vibrator and speaker.
Vibrators and speakers
We have already mentioned that below the Sony Z2 is its vibrator and speaker.
RF line
I believe that many netizens are not unfamiliar with this line, it is a radio line, has an enhanced mobile phone SIM card and Wi-Fi signal.
The cable is very neat
From the map location, we can see clearly that most of Sony Z1 is bonded with the screen panel, even if it is disassembled, it can distinguish the position of different cables. It is more convenient to restore.
Remove all metal shield
Since we have taken the motherboard, the following work is undoubtedly open the shield. Fortunately, the Sony Z2 metal shield is a detachable design, and all shields are easily opened. The figure is taken down all metal shields.
Motherboard back chip diagram
The picture shows the back chip diagram of the motherboard.
Motherboard front chip diagram
The picture shows the front chip of the motherboard. Delicated friends have already seen it, on the two chips on this, there are many graphite coverage, and the effect of graphite is mainly for heat dissipation, which also illustrates the importance of these two chips from the side. What are they? Let us continue to look down.
Qualcomm PM8941 power management chip
The chip that is completely covered by the graphite is just a high-pass PM8941 power management chip. This chip is often used in common use, so additional graphite is required for heat dissipation.
3GB shipping chip + 龙 801 quad-core CPU
This big chip is Samsung K3QF7F70DM-QGCF: SDRAM runs memory chip with a capacity of 3GB. And under this chip, it is also possible to have the most powerful high-pass 801 quad-core processor, the clock is 2.3GHz. Such a powerful two core chips, no extra graphite cooling is absolutely no.
Speaker IC chip
This TFA9890 chip is Sony Z2 speaker IC chip, which allows the integrated DC / DC converter to achieve an unparalleled 9.5V boost voltage. Increasing the voltage margin of the Audio Drive IC prevents the amplifier from cutting the peak and maintains a high sound quality at the maximum volume.
16GB capacity Samsung built-in storage particles
The picture shows the 16GB capacity of Sony Z2 Samsung Built-in storage particles.
Audio decoding chip
The picture shows Qualcomm WCD9320 audio decoding chip, which also allows Sony Z2 to have very good sound.
SKY77619 multi-band power amplifier chip
The picture shows the SKY77619 multi-band power amplifier chip.
SKY77653 Power amplifier chip
The picture shows the SKY77653 power amplifier chip, such a chip supports 4G network signals.
RF transceiver chip WTR1625L
The figure shows the new radio frequency transceiver chip WTR1625L, which is the first product that supports carrier polymerization in the industry, and significantly adds the supportable frequency band number. WTR1625L will support all cellular modes and 2G, 3G, and 4G / LTE all in the world that have been deployed or is a combination of frequency bands and frequency bands that are commercially available.
High-pass PM8841 power management chip
The figure shows the high-pass PM8841 power management chip.
Family Fu + Summary
The picture shows Sony Z2 disassemble the family portrait.
The full text summary: After dismantling Sony Z2, we have a new understanding of this mobile phone. First, from the perspective of work, Sony Z2 still continues the entire design style of the Xperia series, internal construction regulations, easy to disassemble, and do not have all chips on the motherboard, this is also in the future The convenience of maintenance is brought. Overall, Sony Z2 is worthy of 2014 top with flagship.
