How to repair and disassemble the iPad Mini 3 when it doesn't turn on or starts
iPad Mini 3 Logic Board Replacement and Decomposition Procedures 45 steps
[iPad Mini 3 Logic Board Replacement STEP 1]
I think that it is unlikely to remove the logic board usually, but the first failure to suspect is the logic board when it is submerged and it does not start.
It is not an exaggeration to say that the iPad data is the most important part of the part because it is in the logic board, but it is very delicate and must be careful how to handle it.
In order to remove the logic board, it is necessary to remove various parts such as glass and panels, so please work carefully to become long as a decomposition process.
In addition, the dock connector of the iPad Mini3 is soldered to the logic board, so it can be removed at the same time.
[iPad Mini 3 Logic Board Replacement STEP 2]
The liquid crystal glass is only stopped by a strong double-sided tape in the main body, and there is no screw at all.
However, because double-sided tape is very powerful, it is easy to disassemble by using the tool (heat gun) in the image.
Heat gun is a thing like a powerful dryer, and the internal double-sided tape is weakened by applying heat to the place which is enclosed in a red frame by this.
[iPad Mini 3 Logic Board Replacement STEP 3]
After applying heat, the liquid crystal is peeled off, but this decomposition uses a suction cup (orange tool) because the glass is not broken.
However, if the glass is broken, the only way is to peel off it little by little using a tool such as an iron spatula because it is not possible to use a suction cup.
If you insert a pick etc. in the place where the glass was able to float even a little, the work efficiency will be improved because it does not adhere again.
[iPad Mini 3 Logic Board Replacement STEP 4]
If it is able to peel off overall, it will be able to lift the glass.
[iPad Mini 3 Logic Board Replacement STEP 5]
When the glass is peeled off from the main body, it becomes such a state, but it cannot be removed because the connector is still connected internally.
[iPad Mini 3 Logic Board Replacement STEP 6]
To remove liquid crystal glass (digitizer), it is necessary to remove the liquid crystal panel in the decomposition process.
The red circle part of the image is a screw that secures the panel, so try to remove the Phillips screwdriver.
There is a gray sponge on the right side of the image, but when you peel it off, you can see the screw.
[iPad Mini 3 Logic Board Replacement STEP 7]
The screw above is on the upper side, but this is the lower side.
Depending on how the glass is peeled off, the screw may be hidden with tape or magnet, but I think that it is easy to understand because it is in the same part as the screw removed by STEP6.
[iPad Mini 3 Logic Board Replacement STEP 8]
It is a hidden screw.
[iPad Mini 3 Logic Board Replacement STEP 9]
Instead of removing the LCD panel as soon as the previous screw is removed, it is a place where black tape is peeled off using a tool though it peels off because it is stopped even with the tape.
[iPad Mini 3 Logic Board Replacement STEP 10]
The tape is peeled off in this way.
[iPad Mini 3 Logic Board Replacement STEP 11]
The tape above is on the left side, but let's peel off the tape in the same way!
[iPad Mini 3 Logic Board Replacement STEP 12]
I was able to peel off the tape.
[iPad Mini 3 Logic Board Replacement STEP 13]
If four screws and tape can be peeled off, it will be possible to cause a liquid crystal panel, but be careful because it will crack if you try to cause a liquid crystal panel at once because light double-sided tape is attached to the side of the liquid crystal.
Insert a tool such as a spatula and try to wake it up little by little.
[iPad Mini 3 Logic Board Replacement STEP 14]
If you can completely cause the liquid crystal, please knock it down to the glass side as shown in the image.
[iPad Mini 3 Logic Board Replacement STEP 15]
The heat shield is drawn in this way under the panel above.
There is a small screw in the red circle part, so let's remove all!
[iPad Mini 3 Logic Board Replacement STEP 16]
I was able to remove the heat shield.
[iPad Mini 3 Logic Board Replacement STEP 17]
The battery and the connector of the liquid crystal panel are hidden in this part.
Let's remove it because the iron plate can be removed when the screw of the red circle part can be removed!
[iPad Mini 3 Logic Board Replacement STEP 18]
The connector is connected to the logic board, but be sure to remove it from 1.
1 is the connector part of the battery, but you can easily remove the connector from the logic board by lifting it from the bottom to the top.
[iPad Mini 3 Logic Board Replacement STEP 19]
The LCD panel could be removed.
[iPad Mini 3 Logic Board Replacement STEP 20]
I think that I was able to find the red frame part as soon as I was able to remove the panel, but this part becomes a connector of the liquid crystal glass.
You can remove the connector if you try to lift from the bottom to the top.
[iPad Mini 3 Logic Board Replacement STEP 21]
I was able to remove the liquid crystal glass.
[iPad Mini 3 Logic Board Replacement STEP 22]
First of all, I want to remove it from the rear camera (back camera).
Because there is a small screw in the part which is enclosed in a red frame, I remove it.
At the same time, you can remove the iron plate, so please keep it.
[iPad Mini 3 Logic Board Replacement STEP 23]
The rear camera connector is connected to the logic board under the plate above, so let's remove the tool.
[iPad Mini 3 Logic Board Replacement STEP 24]
If you can remove the connector, all you have to do is rub it from under the tool.
[iPad Mini 3 Logic Board Replacement STEP 25]
I was able to remove the rear camera (back camera).
[iPad Mini 3 Logic Board Replacement STEP 26]
Next time, I want to remove the front camera. There is a red frame part next to the rear camera, but it is fixed with black tape, so let's peel it off first.
[iPad Mini 3 Logic Board Replacement STEP 27]
If you can peel off the tape as in the image, I think that the connector was seen, so I will use the tool.
[iPad Mini 3 Logic Board Replacement STEP 28]
There is a foundation around the front camera, but you can easily remove it if you make it from the bottom.
[iPad Mini 3 Logic Board Replacement STEP 29]
I was able to remove the front camera. The battery is removed to make it easier to disassemble in the middle, but the camera can be removed without removing it.
Next, remove the red frame (connector of earphones).
[iPad Mini 3 Logic Board Replacement STEP 30]
The method of disassembly is exactly the same as the front camera of the previous.
[iPad Mini 3 Logic Board Replacement STEP 31]
The cable under the front camera is only fixed with double-sided tape, so it will be peeled off using the tool.
[iPad Mini 3 Logic Board Replacement STEP 32]
Since the cable part becomes double-sided tape as well, the tool is put down and peeled off.
[iPad Mini 3 Logic Board Replacement STEP 33]
There is only one screw in the red circle, so remove the Phillips screwdriver.
[iPad Mini 3 Logic Board Replacement STEP 34]
I was able to remove the earphone jack.
Now you can remove most of the parts connected to the logic board.
After that, remove the logic board, dock connector, and speeder and you're done.
[iPad Mini 3 Logic Board Replacement STEP 35]
First of all, the screw at the bottom of the logic board, but I will remove the connector, but the part that is enclosed in orange will be a connector of Wifi, so you can easily remove it if you wake it up from the bottom.
The screw on the upper right is the logic board, and the lower screw is the dock connector part, so let's remove each!
[iPad Mini 3 Logic Board Replacement STEP 36]
This is the logic board side, but please keep it because you can remove the plate if you remove the screw of the part that is enclosed in red frame.
[iPad Mini 3 Logic Board Replacement STEP 37]
Because there is a connector when the plate can be removed, it is removed by lifting it from the bottom to the top.
[iPad Mini 3 Logic Board Replacement STEP 38]
There is a small screw just below the screw of STEP 35, so let's remove it here.
[iPad Mini 3 Logic Board Replacement STEP 39]
Remove all the red-circled screws before removing the tape from the arrow.
[iPad Mini 3 Logic Board Replacement STEP 40]
Black tape is mainly fixed Wifi cable, but it can be easily peeled off especially because it is not screwed.
[iPad Mini 3 Logic Board Replacement STEP 41]
The large black part on the right side becomes a speaker, but you can easily remove it by removing the cable or tape.
[iPad Mini 3 Logic Board Replacement STEP 42]
This is also the speaker part, but please disassemble it in the manner above.
[iPad Mini 3 Logic Board Replacement STEP 43]
It is a dock connector part, but a black seal is affixed to the part that is surrounded by a red circle, but you can easily peel it off if you turn it over.
[iPad Mini 3 Logic Board Replacement STEP 44]
Let's remove both because the screw comes out when it is possible to turn the seal.
If you pull it when you can remove the screw, you can remove the dock connector.
Because it is soldered to the logic board, please remove it while carefulnot to cut it.
