To date, special repair difficultiesCalifornian smartphones does not arise. Even in a small provincial town there is a workshop where you can fix the “hopelessness bitten by fate.” However, the process of restoring the iPhone 5, the motherboard of which is considered "difficult to lift", will require considerable financial costs from the owner. Why pay extra? To languish in anticipation? Strain your brain with doubts about: "How well will the installed part be?" Isn't it easier to enlist some recommendations and solve the problem yourself? Well, let's save money!
IPhone 5. Motherboard
The description of this part can be reduced tolist the basic hardware components of a smartphone. It may be useful for some readers to find out exactly what is under the shielding housings of the fifth model.
- The A6 processor is located above the sim receiver.
- Accelerometer and two touchscreen-controller are just above the CPU.
- The reverse side of the board (directly under the processor) is equipped with a flash memory chip, above which are: auxiliary memory (LTE), a gyroscope and a Wi-Fi module.
- Two power controllers are located slightly below.
It should be noted that the CPU is filled with a special substance - a compound, which significantly complicates the process of its repair.
Works - do not touch!
To replace the motherboard iPhone 5 wasjustifiable process, you need to be sure that the part really requires replacement. Fictitious reasons: “something does not work” or “probably, the motherboard is covered” is not a reason for cardinal modification of your “humble electronic servant”. You must have good reasons for making this kind of decision. After all, the motherboard of a smartphone, in fact, is the mobile phone itself. As you know, a mistake can cost you dearly. Therefore, you must clearly understand what exactly is causing the iPhone 5 to break.

- The smartphone has been subject to a short circuit.
- Some parts of the body frame are heated very much.
- Phone "hard" fell.
- Visually there are signs of deformation of the hull: kink, kinks and other types of “asymmetry”.
Any mechanical damage to the smartphonecaused a partial or complete loss of device performance, first of all, it needs software diagnostics. However, when you are fully confident that the main board has become unusable, follow the instructions below.
Dismantling the main part of the smartphone
As mentioned earlier, maternal repairsThe iPhone 5 board is possible in principle, but due to the complex arrangement of components and the use of some technological "chips" by the manufacturer in the factory installation, this incredibly time-consuming exercise is doomed to failure (even in the hands of experienced craftsmen). As practice shows, it is much more expedient to purchase a new or used used board.
So, for the direct installation of the working "motherboard" you will need:
- Apple screwdriver set.
- Tweezers.
- Plastic spatula (old credit card).
- Sucker for removing the iPhone 5 screen module.
The motherboard is dismantled elementary.However, without this tool, you just can not do. Believe me, the use of traditional screwdrivers and a kitchen knife will not lead to anything good - proven!
Step one: remove the battery
- Remove the two end bolts on the front of the smartphone.
- Using the sucker, gently lift the bottom edge of the screen module.
Attention: in the upper right corner (under the touch panel) there are connecting loops that can be damaged during careless actions.
- Unscrew the protective cover of the connectors (top right, right) - three screws.
- Disconnect the touch and display loop.
- To the right of the battery (under the SIM receiver), unscrew two more protective elements.
- Disconnect the battery connector and pull the battery out of the case.
The second step: disconnecting coaxial cables and strapping lines
After you managed to dismantle the battery, switch your attention to the right side of the iPhone 5 smartphone.
- The motherboard is mounted with five cross-head screws.
- At the top of the phone (the inner end of the case) there are two more bolts fixing the part to be removed.
Attention: before unscrewing the above-mentioned bolts, carefully disconnect all visible connecting components of the phone. Then carefully turn the board to the left.
- Disconnect the two coaxial cables (top and bottom of the board).
- Remove the "motherboard" of the smartphone from the bowels of the body.
Now install the new part in the reverse order.
Summing up
As you have noticed, the replacement of the motherboardiPhone 5 is elementary executable. Even an unintelligent person in electronics will be able to implement this kind of repair process without much difficulty. However, remember: extreme attention and caution in actions will significantly increase your chances of success of the enterprise. Good luck to you!
