IPhone 5: motherboard. Replacing the motherboard

Today, there are no special difficulties with the repair of California smartphones. Even in a small provincial town there is a workshop in which you can fix "hopeless fate". However, the process of restoring the iPhone 5, whose motherboard is considered "difficult to climb," will require considerable financial costs from the owner. Why pay extra? To languish in anticipation? Strain your brain with doubts about: "How good is the installed part"? Is it not 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 to enumeration of the main hardware components of the smartphone. Perhaps, for some readers it will be useful to know what exactly is under the shielding covers of the fifth model.

• The A6 processor is located above the sim-receiver.
• The accelerometer and two touchscreen controllers 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), gyroscope and Wi-Fi module.
• The two power controllers are slightly lower.

It is worth noting that the CPU is flooded with a special substance - a compound, which significantly complicates the process of its repair.

Works - do not touch!

To replace the motherboard iPhone 5 proved to be a justified process, you need to be sure that the part really needs replacement. Fictitious reasons: "something is not working" or "maybe the motherboard is covered" is not yet an occasion for a radical modification of your "submissive electronic servant". You must have good reasons for making this kind of decision. After all, the motherboard of the smartphone, in fact, is the mobile phone itself. As you know, a mistake can be costly to you. Therefore, it is necessary to clearly understand what exactly is the cause of the breakdown of the iPhone 5.

The motherboard needs replacing if ...

• The smartphone was short-circuited.
• Some parts of the frame are heated very much.
• Phone "hard" fell.
• Visually there are signs of deformation of the hull: fracture, kinks and other kind of "asymmetry".

Any mechanical damage to the smartphone, which caused a partial or complete loss of the device's performance, first of all, requires software diagnostics. However, when you are completely sure that the main board has become unusable, follow the instructions below.

Dismantling the main part of the smartphone

As mentioned earlier, the repair of the motherboard iPhone 5, in principle, is possible, but, in view of the complicated arrangement of components and the use of some technological chips by the manufacturer at factory installation, this is an incredibly time-consuming task, in general, doomed to failure (even In the hands of experienced masters). As practice shows, it is much more expedient to purchase a new or working second-hand payment.

So, to conduct a direct installation of the working "motherboard" you will need:

• A set of Apple screwdrivers.
• Tweezers.
• Plastic spatula (old credit card).
• Suction cup for removing the iPhone 5 screen module.

The motherboard is dismantled elementary. However, without this tool you just can not do. Believe me, using traditional screwdrivers and a kitchen knife will not lead to anything good - it's proved!

Action one: remove the battery

• Unscrew the two end bolts on the front of the smartphone.
• Using the suction cup, gently pry the bottom edge of the screen module.

Attention: in the upper right corner (under the touch panel) there are connecting loops, which can be damaged by careless actions.

• Unscrew the protective cover of the connectors (top, right) - three screws.
• Disconnect the sensor and display cable.
• 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.

Second action: disconnection of coaxial cables and strapping cables

After you managed to dismantle the battery, switch your attention to the right side of the iPhone 5 smartphone.

• The motherboard is attached using five cross-shaped screws.
• At the top of the phone (internal end of the case) are two more bolts, fixing the part we are dismantling.

Attention: before unscrewing the above bolts, carefully disconnect all visible connection components of the phone. After gently flip the board to the left.

• Disconnect the two coaxial cables (the top and bottom of the board).
• Remove the "motherboard" smartphone from the depths of the shell.

Now install the new part in the reverse order.

Summing up

As you managed to notice, the replacement of the iPhone 5 motherboard is elementary. Even an ignorant person in electronics can easily implement such a repair process without special difficulties. However, remember: the utmost attention and caution in actions will significantly increase your chances of success of the enterprise. All the best!
