The parts that are the most important parts in the iPhone are not limited to iPhone7, but all data etc. are included in the logic board.
It is unlikely to remove the logic board when using normally, but if the iPhone is submerged, the need to remove it with a high probability comes out.
It is the content that you can remember as a decomposition method because rust occurs when it dries and it is left as it is, and the power of the iPhone does not turn on.
However, since it is necessary to remove various parts until removing the logic board, those who do not have themselves in the decomposition please judge by looking at the following process!
I will continue to disassemble the iPhone7 from here, but let's remove each tray of sim card first!
The sim tray can be easily removed using the pins that were included in the accessories at the time of iPhone purchase.
Since the iPhone7 is waterproof, a waterproof seal is affixed around the inside of the liquid crystal.
The tool in the image is called a heat gun, and it is not necessarily an indispensable tool though it is a tool which made the dryer strong if it says plainly.
If you are new to disassembly of the iPhone itself, you can work smoothly because the seal will be soft if you use it, but it is possible to substitute even a dryer once.
Up to now, the iPhone has been to wake the LCD from the home button side to the camera side, but this iPhone7 will open the LCD so as to wake up from left to right.
First of all, the tool is inserted into the position where the spatula is located and it floats little by little, but it becomes easy to disassemble when the suction cup (orange) is used together.
If you try to cause it forcibly, the liquid crystal side will crack, or it will lead to other failures, so we will open it slowly.
If you can float the liquid crystal even a little, it is good to insert a pick etc. like the image!
By doing this, the liquid crystal will not close again!
Now we will open the gap on the left side.
If you look closely at the inside of the part that could be opened, you will see a black seal or a white seal, but it will peel off regardless because it is a waterproof seal.
A waterproof seal is attached to one lap of the liquid crystal, but please pay attention only around the camera (upper part).
At the moment, I think that I was able to float the liquid crystal of the left and right slightly below, but the upper part does not decompose in the same way because the nail is caught inside, and a little knack is done.
If you pull the liquid crystal lightly in the direction of the arrow, there will be a slight gap between the main body and the liquid crystal, but when the waterproof seal comes into view, please peel off the seal in the gap.
By doing so, it is possible to wake up the LCD panel from the left side to the right side.
The first decomposition to be done after opening is work to remove the battery connector from the logic board, but since it is connected under the iron plate of the image, all screws of the red circle part are removed.
Four screws of this part are not Phillips, so please be sure to use a special tool because you can not open it unless you have a Y-shaped screwdriver!
I own several Y-shaped drivers, but I couldn't take them off right away because the sizes were slightly different.
I thought that I would try to disassemble it forcefully as it is, but I am using a special tool because the risk of licking from the experience up to now was high.
The red arrow part becomes the connector of the battery, but the connector can be removed from the logic board by lifting from the bottom to the top using the tool.
Next, the cable on the liquid crystal side is removed, but it decomposes in the same way as the method which removed the connector of the previous battery.
In the previous iPhone series, the connector relationship of the LCD was all gathered on the upper side (upper right), but in the case of the iPhone7, it is one of the changes because it became the lower right!
Because there is a connector in the inside when the screw can be removed, it is possible to remove it if it is made to lift from the bottom to the top.
Since it was possible to separate the body side and the liquid crystal side of the iPhone7 with this, please keep the liquid crystal side as it is.
After removing the liquid crystal, it is easier to disassemble it if the battery is also removed. Click here to replace the iPhone7 battery
Remove the two red-circled screws by using the tool and removing the two red-circled screws.
There is a Wifi cable in the arrow part, but you can easily remove it if you cause it from the bottom to the top.
This is the position around the camera and the upper part, but first, all the screws that are enclosed in a red circle are removed.
The screw of the light blue part is on the side, so don't forget to remove it!
I think that I was able to remove each plate when I was able to remove the screw of the previous, but there is a connector (orange part) under it, so Remove it from the bottom to the top, and remove all screws that are enclosed in a red circle.
The light blue part has screws on the side, so don't forget to remove it!
Because there is a small connector next to the camera, I try to wake it up from the bottom and remove it.
The cable part other than the connector is only fixed with double-sided tape, so it will peel off using the tool.
I was able to remove the logic board.
If all screws and connectors are removed, it can be easily removed, but the projection of the sim card part hits and it may be difficult to remove.
In that case, you can easily remove it if you push the protrusion.
