First, there is a 17 screws back
After two years of precipitation, hammer end phones meet with us, we leave alone the old law if fulfilled his promise, whether the phone is not perfect enough to talk about the hammer, more talk about how to use feelings to make a smart phone We want to say only one thing today – to work, hammer phone as a hardware terminal products, in addition to performance and experience there are two very important basic elements, that is, design and workmanship, and today I will be ready to practice together, and this is the first tour of the hammer inside the phone.
Big Secret hammer phones work
Although the phone does not support the hammer to replace the battery, but in fact it’s the back cover is open, we need to open the back cover of the phone hammer, because we can directly see the 17 screw it back on! You heard it right, that is, 17 screws, and this is just the beginning, there are more exciting behind.
Open body back
Remove the plate to remove the 17 screws after
In fact, do not completely remove the 17 screws, the middle piece of steel also can be removed, but because of the length, weight as well as these types of screws are different, so removed to put together position is a good choice, if You have nothing to disassemble the experience, then this advice applies to any device for dismantling.
Hammer phone lithium polymer battery
A patch to protect the individual cable
After removing the plates, we can see the lower right corner with two small screws patch, they are used to protect the underlying cell of the cable screens.Remove these screws we can unload the battery cable and the battery removed, but to note that, although there are two plastic sheets used to assist in removing the battery, but the middle is still glued to live, do not be too Violence removed, because this is no “skin” of the lithium polymer battery is very soft.
2 long strip of highly integrated motherboard
After removing the battery, we can very clearly see the general structure of a hammer inside the phone the whole body, and the right motherboard elongated strip, there are two parts of the upper and lower pressure on the motherboard, this time we can not directly remove motherboard, and the motherboard has two screws on the frame.
You can see the general structure after removing the battery
Remove the plastic plate pieces unscrew the three screws
In fact, at this time there is a screw on the metal frame in order to see the main camera, and during the next ten million check cable between the motherboard is removed are, after all, as fragile wire cable is very easy to break .
Various holes on the front panel
Vibration unit + proximity sensor, and light
The left is the main camera has a front camera test
Want dismantling the top part, need to be covered in plastic sheets above the take down, then we can see three screws, removed the plastic box at the top we can see the original front camera, proximity sensor, light +, etc. The whole design is very clever, and very reliable fixed, from here we can see the circular vibration unit.
Most of the chip on the motherboard has a metal shield to protect
Then we can carefully remove the motherboard, the motherboard because the bottom line so they will have an RF caution. We can see the hammer phone motherboard with a long strip of this design, two-sided structure, integration is still very high.
MBG965H Hynix chip and 2GB RAM
OPA2604AU op-amp chip
Since most of the chips are welded with a shield on the motherboard, we can see that the chip is not much like this very conspicuous by ARM Holdings chips produced MBG965H, and Hynix (SKhynix) of 2GB RAM chip , as well as at the press conference to OPA2604AU old Zloty op-amp chips, although these chips but do not have the heat shield patch or thermal grease and other stick.
Three of four fuselage structure
After removing the motherboard, let us look at the bottom of the structure hammer phone, ditto the bottom portion of the same piece of plastic cover, we can see the other end of the RF cable also need to be careful to pull down. Then we can carefully disassemble by card or special tools to remove the brown piece of metal, because the use of the adhesive and the texture itself is relatively fragile, so be extra careful.
Bottom of the fuselage also has a plastic cover
After the open structure is also more complicated
Demolition brown metallic stickers
The whole picture microUSB plug tail
The lower left corner there is a small PCB board needs attention
After removing the brown metal, the entire tail microUSB plug can be unloaded, and then we can see a two-tier PCB circuit chip, the lower left corner there is a small PCB board with screws to live, do you think the demolition here Even if you’re done? Of course not, we can see a hammer inside the phone left and right sides are silver metal frame, the middle line is the hammer with rows of two pairs of volume buttons of the phone cable, fixed them by removing the screws that we will not only be able to remove these two button, but also separate from the frame and the front panel.
The volume key frame around each four screws
Two pairs of the volume keys is indeed a cable
After the front panel and the frame can be separated
Three physical buttons
Hammer phone family portrait
Then we can see the physical buttons on the front panel, we can see their contacts as well as in front of the key part of the overall design is very compact. Here we will end up dismantling the whole, we can see the phone a total hammer back, internal steel frame portion and the front panel of four-layer structure.
During the dismantling, the author is only one emotion – screw more, really more, and the internal structure is very clever, the entire cable alignment, as well as the location is very neat, although many cable and small parts, but definitely chaos. Entire fuselage structure in only two snaps, and the rest are all screwed, which makes the strength of the whole body is greatly improved, and more stable, the process also increases the difficulty of many, the most important is the direct result of this upgrade costs , to be exaggerated point, then, just on the hammer on the phone is worthy of this work it is 3000 yuan pricing, workmanship and design really stronger than the iPhone , which is the author of the current split-off material most conscientious a cell phone. Here I do not want to use feelings, what detail to describe, just screw it nearly 40 artisans will be able to interpret what is spiritual.
