These conditions should be cautious | otherwise repair machine damage to destroy the scene

To be honest, it feels like today's 2018 hands-on ability seems to have improved a lot.For the simplest example, under the bridge 'foil Boys' is less than a year, recently just happened to iPhone down-frequency Things, many users have chosen to buy their own batteries for the change, but to repair their own cell phone this kind of thing, the success is good, but if accidentally crashed, or even damage caused by the second becomes more harm than good.

Therefore, for their own maintenance of mobile phones, and even simple maintenance clean are still a little cautious.Although the three defenses have become almost a standard mobile phone, but in essence the phone is still a highly integrated digital 'fragile So when we do it yourself cell phone repair, the following few points must pay attention.

1. Battery! Must first pick the battery!

This standard applies not only to mobile phones, but also to almost all electronic devices. Of course, almost all mobile phones are now non-removable, and removing the battery is unlikely. All we need to do is open the rear cover of the phone After (or the front panel, depending on the phone) the first time to disconnect the battery power cable.

Why do we do? Although we must dismantle the phone when it belongs to the shutdown state, but because the power supply is also connected to the circuit, so the circuit is still charged, and many of our metal tools and fingers are conductive and static electricity, touch the motherboard , Resulting in a short circuit, it will break the circuit, resulting in the paralysis of the motherboard, so the first step you need to first separate the battery and the motherboard connection.

So, no matter what you need to change the battery, the screen or even just want to open a simple clean up the phone's internal environment, immediately disconnect the battery power cable is the first thing we have to do. Another point to note, especially In the dry northern - the accumulation of static electricity, so in the beginning of disassembly, it is best to first release the body's electrostatic discharge, after all, who do not want to repair your cell phone into a ruined cell phone.

2. separate back shell, heat gun is a good thing

According to the past classification, usually the screen or the back shell is fixed in three ways, according to the ease of disassembly can be divided into screw fixation, strong double-sided adhesive tape and buckle fixed.But today's cell phone in order to ensure that the structure is also reliable Two or more fixing methods may be used at the same time. Screw fixing can not be used alone to fix the screen or the back shell, so it is generally combined with the latter two.

Understand the fixed way after the natural is to learn how to disassemble, in general, according to the screw - double-sided tape - buckle method to disassemble just fine. However, the current trend of handset manufacturers is to add waterproofing to their own products - even if Some manufacturers did not use this as a selling point, their products are actually more or less have a certain degree of waterproof capacity, while on the other hand, the re-popular double-sided glass design so that the buckle-style design is not as popular as in the past, but the iPhone is a Exceptions, it has screws - Double-sided tape - Triple buckle protection.

So for the glass back cover phone, the dismantling of the first big threshold is how to open the back cover (and to ensure that it is intact) Well, then for our average user, the three may be fixed inside the most unfriendly is double Face gel fixed.

Because after heating, the viscosity of the glue will be reduced a lot, so professional maintenance will prepare the heating station and heat gun as a dismantling tool.But for most of us these two things are not so easy, but we have more simple and easy to get Tools: electric hair dryer.

We use hair dryer hot air heating 3 minutes or so and then dismantling, Heated to touch the somatosensory touch hot subject, after heating the sucker or pry bar to the screen or the back shell opened a gap, then the first stick to keep sticking state, and then use the second to continue to expand the gap to a Node and then add the third or even the fourth pry bar during the If you encounter more difficult to degumming the site, continue to heat and then Alice can open the crowbar as far as possible with a thin, pliable thinner Alice more easily Insert the gap, the more flexible Alice Alice less likely to damage the screen or glass.

However, after dismantling the lid / screen there is a point to note: The first is to shut down, and then remove the Sim slot. Shutdown is to power off the device to prevent the teardown process short circuit; separate Sim card slot is in the dismantling process because it stuck in between the body and the motherboard Disassembly can not continue. There are many novices will try to disassemble forget this step lead to a card in the first step.

3. Routine maintenance is also a big deal

In fact, some of the 'accident' is not 'natural disaster' but 'man-made' at all. If you usually take a little care of your cell phone, in fact, you can avoid a lot of unnecessary damage.

The simplest example: Although some phones are currently using a three-defense design, but that does not mean that you can take a shower with it - hot water vapor is more likely to invade into the phone than water, though not necessarily A try will make the phone into the water, but this attempt is still very dangerous.

If the phone is not waterproof design, then it is even more 'delicate' screen dirty want to wipe the wipes? This is no problem, of course, but beware of your top of the screen there is not waterproof handset, if the approach is too ' Rough "may clean the screen, but ruined the handset.

So, to clean the electronics, I recommend using alcohol - the best alcohol-free alcohol, and the most common type of alcohol is harmless. For the headphone jack or the data port, gently wipe with a cotton swab dipped in a small amount of alcohol. In terms of alcohol as an organic solvent than the cleaning ability of water stronger, on the other hand the characteristics of rapid evaporation so that it will not cause damage to electronic components.

Incidentally, the electronic product into the cylinder after the water into the operation for saving the phone with you to clean it under the sun for a while may be no difference. If the phone just splashed water, into the rice heap Perhaps useful, if dropped into the water, then the role can be neglected.

4. Write in the last advice

Although I found out in the article for those who disassemble and repair the phone will inevitably encounter those mine, but want to really get started with the ability to disassemble a cell phone, for novices still have a long way to go But now the Internet is so developed, almost all the market dismantling the phone you can find pictures and even video tutorials as a guide.

So when your security cell phone there is a big or small problems, blindly choose their own repair / official repair is not too wise choice.According to their own mobile phone disassembly difficulty, maintenance costs and other factors to consider after a selection of the most Excellent solution may be a more appropriate choice.

If you want to dismantle the problem machine in your hand and see if it can be rejuvenated in the second spring, you may wish to come to the village to see. We have a comprehensive and systematic disassembly report on many mobile phones. There is no way to repair or may wish to come to the village to see what new machines for you recently. (Laughs)
