Naturally, to repair phones you need tools and equipment. Moreover, the more difficult the repair is supposed to be, the more complex and expensive equipment will be needed. Screwdrivers alone are not enough. So, I'll start with the bare minimum:
1.
Screwdriver Set. To begin with, you will need ordinary flat and figured (phillips) screwdrivers, preferably small + at least 3 asterisk screwdrivers. They have exactly the same shape and differ only in dimension. To begin with, we need the sizes T5, T6, T7. These are the most commonly used screw sizes. mobile phones and similar technology. You can also purchase a set of screwdrivers, which immediately contains all the necessary varieties of interchangeable nozzles. The inconvenience of such a set is that you often have to change nozzles.
2. scalpel. An indispensable thing for stripping wires, tracks, etc. You can buy at any pharmacy. Preferably, of course, the old domestic scalpel, as they are almost eternal. The current ones become dull very quickly and all kinds of notches appear on the blade.
3. A set of tweezers
. It is desirable to have at least 2 types: straight and curved. You will appreciate the advantages of each during the repair process. You can get by with one, but, in some cases, you just need to crawl into a hard-to-reach place with the help of one or another.
4. Pencil-eraser-brush
. A very handy thing. At first glance, an ordinary pencil, but instead of the usual core, it has an eraser (eraser) core. Designed for cleaning contact surfaces from oxides, dirt, darkening, etc. After this treatment, the contacts look like new - shiny and beautiful. On the reverse side of the pencil there is a brush, which is very convenient to sweep away the “erasure products”, as well as the usual saw and similar dirt that accumulates during the operation of the phone.
5. Toothbrush- new or used (most importantly, not vice versa). Designed mainly to remove small oxides as a result of moisture entering the phone. Used in conjunction with special liquid ("wash").
6. Multimeteris a much needed tool. The method of various measurements allows you to learn a lot about the state of the phone and is one of the main tools for diagnosing faults and repairing the phone. The model of the multimeter is not critical, since all have the necessary functions. Let me just say that you should not buy the cheapest "China", as they are unreliable and the readings during measurements are not always accurate.
7. Universal network Charger
. Also a must have in your arsenal. Allows you to charge any battery cell phone, digital camera, which is very important in the repair process. After all, devices often come with discharged batteries and without their regular charger (over time, of course, you need to get all possible chargers and preferably original ones). This is where this SZU comes to the rescue, popularly referred to as “crab”, “frog”, etc.
8. Hot air soldering station
. Mandatory required. Without it, complex repairs (with re-soldering of chips, filters, etc.) cannot be done. Designed for dismantling and subsequent mounting of chips in the BGA package (and others in modern phone practically no) by heating with a stream of directed hot air with adjustment of the flow force and temperature.
9. Microscope.It is necessary for a thorough visual inspection of the mobile phone board and its components during the repair process, as well as when performing fine work using soldering, the accuracy of installing BGA chips and other elements on their seats (positioning), as well as subsequent control. Find the right microscope hereoptical instruments in Rostov-on-Don.
10. Card holder.
An indispensable thing in the repair of complex microelectronics. It allows you to securely hold boards of different sizes, thereby facilitating the work of the master, since there is no need to hold the board by hand. Structurally come in a variety of configurations and sizes.
11. Ultrasonic bath (UZV)
. Without it, about repairing cell phones that have been exposed to moisture, water, beer, coffee J, etc. you can forget. We all know that electronics is not friendly with water and its derivatives. Numerous oxides with their miracles instantly appear in all chains (especially feeding ones). It is impossible to clean such a board in the usual dry mechanical way. You have to resort to special cleaning. liquids using a coarse brush. By the way, I will say right away - all sorts of colognes and alcohol are not suitable !!! But, most often, this cleaning method is ineffective, since moisture penetrates into all possible and impossible places and brings us, repairmen, a lot of problems. But not everything is so bad if there is an ultrasonic bath. Again a warning - the well-known "Retona" is not what we need and does not relate to our business in any way.
Very easy to use and relatively reliable in normal use. It works like this: either only distilled water is poured into the bath itself, or it is the same, but with a small addition of various means that make it a little easier to clean the board. These are different solvents such as "Mr. Muscle", "FAIRY" and the like. The level fills about a little more than half of the bath. Next, a board that has become stale and oxidized earlier is placed in the bath, and then the ultrasonic cleaning process itself is turned on.
Such RASs most often have two fixed power levels - usually 30W and 50-60W, which are switched on separately. The ultrasonic cleaning process looks like this: a radiating element (piezoquartz) is rigidly attached to the bottom of the bath itself, which emits vibrations with a frequency of approximately 40-60 kHz and mechanically transmits them through the bottom of the bath itself to the liquid that is poured into it. Further, due to cavitation (cavitation is the propagation of sound waves in a liquid), the board is washed, as well as the splitting and destruction of the formed oxides and sulfates on the surface of the board and elements.
The ultrasonic bath does not require special care. The main thing is to prevent liquid from spilling into the case, otherwise failure is inevitable. If the case is not sealed, it is advisable to do this in advance with an ordinary sealant. It is also not recommended to turn on the RAS at idle or with a liquid level much lower than the average, since the piezoelectric element will be heavily loaded and may fail prematurely.
12. BGA - stencils and BGA - paste
. For beginners, it is unlikely to be a useful necessity, but if you are planning to seriously engage in reballing BGA chips, then these materials are simply necessary for you.
And that's what. The peculiarity of the design of microcircuits in the BGA package provides for the absence of contact pins that are familiar to us, which can be soldered with an ordinary thin soldering iron. Flat contact pads are located on the bottom of the case, and soldering such a chip to the board is carried out by applying solder to the contact pads. As a result, they look like small balls, which must be of the same size and shape. After that, such a microcircuit is installed in its place and, after melting the solder, settles a little, as a result of which the gap between the microcircuit and the board remains quite miserable - just the size of the settled solder balls.
The fact is that if it becomes necessary to dismantle the BGA microcircuit, then the molten solder balls are torn at the moment the chip is removed. One part of the solder remains on the board, the other on the chip itself. It is impossible to install such a chip back without preparing (knurling) new solder contact balls. For this, we need stencils and solder paste for BGA reballing.
As for the solder paste for knurling new balls on BGA chips, here the choice is formed after testing several brands and types. As the saying goes, to each his own. Some people need it thicker, some more liquid.
13. No-Clean Flux Gel
. It is applied to the soldering of radio-electronic components. It has a high boiling point, so it is excellent for mounting chips in BGA packages with a small distance between the contact balls, the leads and the board surface. Non-cleaning means that it has no chemical activity after soldering and, accordingly, does not cause corrosive damage to soldered elements in the event that it is impossible to remove flux residues. Also, after hardening, the flux forms a certain film on the elements and between them, which provides additional protection against oxidation and moisture ingress.
14. Braid for desoldering
. It is designed to prepare soldering places and is used to remove excess solder on contact pads. Ideal for preparation of BGA chip soldering areas.
15. Electric soldering iron 25W and 40W.
For soldering massive discrete elements with a large heat sink. In the repair of mobile phones, they are used less often, but they are necessary. For example, the seats of charging connectors, headsets, etc. warm up well.
16. Power supply (PSU)
. When repairing phones, and not only, it is simply necessary. When diagnosing and repairing, it becomes necessary to power the device precisely from the PSU to monitor certain processes, as well as in the event of a complete discharge of the battery or its absence. Suitable for our purposes adjustable block power supply with an output voltage of 0 - 15 Volts and a current of 1 Ampere or more. When choosing a PSU, you should pay attention to the presence of voltage and current indicators in it, since we need to control these parameters during diagnostics and repair. PSUs are sold with digital and analog (needle) indicators. So, it is preferable to have a power supply unit with analog indicators, since they are visually much more informative, especially with rapidly changing processes due to their very low inertia. Digital indicators are not always able to display the change in one or another parameter and, most often, display only extreme values.
Most often, PSUs are bundled only power cord, and at the output only terminals - clamps for connecting connecting wires, with which the consumer will be connected. It is very convenient to connect red and black wires to the "+" and "-" terminals, respectively, at the ends of which to fix small crocodile clips.
17. Oscilloscope- an electronic device that is designed to measure and then visually display on the screen a wide variety of quantities and signals, their amplitude and shape. There are the most different types. There are no special requirements for this device, the main thing is that it is in good working order and has a bandwidth of at least 50 - 100 MHz. Well, which one to choose - on a cathode ray tube or with an LCD, large or small - it's up to you. Here the question already consists in the price and your opportunities.
18. Computer with Internet access.
It all depends on your preferences. As for the computer, it is for the repair of high performance that is not required. The main thing is that the programs are loaded quickly and it is comfortable to work in them. There is only one caveat: to work with phones that require updating or restoring software, the computer must be protected from accidental voltage drops in the network or even shutting it down. For these purposes it is necessary to use the source uninterruptible power supply(UPS) or, preferably, a laptop. For software repair, it is recommended to have a separate computer on which only programs for working with the corresponding programmers are installed and, of course, a set of all current firmware for the maximum possible number of phones. In any case, if the computer is connected to the Internet, it will not be difficult to download this or that firmware.
19. Set of programmers
for software repair of cell phones. There are a large number of programmers, both universal - with support a large number brands of phones, and designed for a specific brand (manufacturer) phones. One and the best does not exist. Therefore, before buying, you need to familiarize yourself with the possibilities of several and choose for yourself according to financial capabilities and, accordingly, repair needs. And as needed, buy the necessary programmers.
Even a novice master will not cope with solving the simplest tasks if he does not have certain ones “at hand”. Especially if the specialist intends to restore electronic gadgets, communications. Let's say right away that cell phones cannot be restored “on the knee”, you will have to incur certain material costs for arranging the workplace. We will not enumerate cutting-edge devices; in the framework of the article, we will present only a set of the most necessary for a professional.
Let's start with the most elementary and simple - with classical instruments. In the list, we present the main types that you really can’t do without:
1. It will be necessary to purchase. Moreover, flat and cruciform versions of several “running” sizes will be required. Don't forget to order torx screwdrivers. As for the dimension, it must comply with the standards from T5 to T7. It's also a good idea to get a set with interchangeable nozzles. In this case, there will definitely not be problems with disassembling the case, other components of the device.
2. When assembling a set of repair tools, do not forget about such an important thing as a scalpel. It is with its help that you can very easily clean the tracks, wires. Try not to skimp on the accessory - notches will appear quite quickly on a budget copy.
3. You will definitely need a pair of tweezers. Look for a standard pattern and one curved one that will allow you to get to hard-to-reach elements.
4. An eraser pencil, made in the form of a classic pencil, will definitely come in handy. With it, it is easy to clean oxidized contact coatings. You will need a little time to put in order badly neglected contacts.
5. Do not be surprised, but experts often use toothbrushes in order to cope with minor oxides when working with “recessed” smartphone models. Great efficiency can be achieved in combination with a special liquid, called a wash by service specialists.
6. The holder, in which the board is firmly fixed, greatly facilitates the workflow. It is easier for a person to do fine work when a small fragile element is fixed.
Quite often in service centers visitors bring failed gadgets in a fully discharged state. Be sure to keep a charger available that can charge any battery. In this case, there will be no difficulties in testing the performance of electronics.
Take care of the order. Often during the testing process, there is an urgent need to power the phone from the PSU in order to track the corresponding operating parameters. Such an element is also very important when the smartphone battery is completely unusable or in its absence. Stop the choice on the product with the following parameters: for output voltage within 0 - 15 Volts, for current at least 1 Ampere. It is necessary to order samples equipped with indicators, because only in this case it will be possible to accurately fix certain operating parameters. As professional workers of specialized centers advise, preference should be given to devices with a pointer indication, it is much easier to read it during testing.
You will have to spend a lot of money on a soldering device, on additional tools from this series and related accessories. So, here is a small list of working tools from this series:
1. Be mentally prepared for the fact that the standard will not save you. You will need to select a special soldering station. Only with its help you can achieve amazingly accurate results if you need to solder chips, if you need to replace filters. Modern hot air models significantly facilitate the work of the master, due to the high degree of reliability, the service will provide long-term guarantees when performing complex tasks.
2. Experts advise buying BGA stencils, in parallel, you need to stock up on BGA paste. As practice shows, it is these elements that will be required when carrying out particularly delicate work. As for the selection of a brand of pasta, here rely on your preferences. It is convenient for some to work with a thick paste, many masters prefer a more liquid modification.
3. As you can see, not only tools for repairing phones are needed, but dozens of “little things” should be purchased. You will definitely need a no-clean flux gel. The substance boils at a very high temperature, so it is indispensable for mounting chips in elements such as BGA packages. Why is the product called no-clean? The fact is that it is distinguished by the complete absence of chemical activity after soldering is completed. Accordingly, there is no further risk of component damage due to corrosion. In addition, it provides additional protection from moisture.
4. A convenient addition will be a special braid, which greatly facilitates the removal of solder. The process of removing excess is greatly simplified and takes less time.
5. Not as a main, but as an auxiliary device, you will need a conventional electric soldering iron with 40W characteristics. It is needed when working with large discrete components with significant heat dissipation. Such an accessory is indispensable when preparing landing points for charging connectors and other similar elements.
Another expensive purchase will be a microscope. Even a person with excellent eyesight cannot do without it. With its help, boards and other small details are viewed. With its help, especially delicate, responsible work is performed, requiring maximum eye strain. In addition, look at several magnifiers of different power. They will be a great addition to a stationary device. Sometimes some detail is more convenient to consider in the hands.
It is not at all easy, and sometimes impossible, to identify a complex breakdown thanks to one experience. To achieve the goal, you will need special equipment for repairing the phone, which serves to test the operability of communication facilities. Within the framework of the section, devices are presented that will help to quickly identify a malfunction:
1. The first in importance is the multimeter. This is one of the main instances that allows you to identify technical problems. As for the model line, there are no special recommendations here. The main thing that should be emphasized in the process of searching for a product is the accuracy of the readings. You can judge this by reading the opinions of real users.
2. It is problematic to restore a recessed smartphone without an ultrasonic bath. No fine scrupulous cleaning with special means will save the situation! It is possible that you will restore the means of communication, but it will work for a very short time. Guarantees should be given only if there is a special bath. Thanks to the vibrations of ultrasound, it is possible to achieve phenomenal results in seemingly hopeless situations. Practice knows many cases when in this way it was possible to restore hopeless "drowned people" for many years. The secret of effectiveness is quite simple - this is how the effects of oxides and the manifestation of sulphations are destroyed. Impeccable quality of cleaning the board is not difficult to achieve, for this you must follow the standard recommendations of the manufacturer.
3. Significant support in solving complex problems will be provided by the oscilloscope. It is able to measure and then display various types of signals, show operating amplitudes. IN this case There are no specific recommendations either. Main advice- try to opt for a sample with fairly accurate readings.
4. The most important mobile phone repair tool today is regular computer, any laptop. Don't chase high performance, fashion model. It is better to spend these funds on diagnostic products. Take care to install the appropriate software to make it more convenient to work when flashing phones. It is impossible to foresee all situations, so you will definitely need Internet access to download programs and data.
5. You will need a certain set of programmers, there are a great many of them at the moment. There are universal products designed for communication equipment of several brands. There are narrowly targeted samples designed to work with a single manufacturer. There is no single choice recommendation. It is necessary to take into account the preferences of potential customers in the area where the service is located, to listen to the opinion of more experienced colleagues.
When choosing the equipment you like, never be in a hurry. Always compare it with other copies released under a different brand name. Compare cost, performance, accuracy, ease of use. Do not be lazy to get acquainted with the feedback from consumers who have already formed their own opinion about the possibilities specific device. Then the risk of errors in the selection process will be significantly reduced.
Even a novice master will not cope with solving the simplest tasks if he does not have certain ones “at hand”. Especially if the specialist intends to restore electronic gadgets, communications.

Today, the service for the repair of smartphones and tablets is in high demand. Even in small towns and villages there are four or five workshops for repairing mobile equipment, and it seems to many beginners that they can’t break through. In fact, things are not so at all.
If you have a desire to try your hand at this business, then you can start small, namely, acquire a minimum set of tools for repairing smartphones and tablets. And then the question arises, what to buy in the first place? We'll talk about this.
Of the devices and materials that are most often required when repairing smartphones and tablets, I would single out the following:
The list turned out to be small, as I tried to indicate only what has been most often used in practice over the past few years.
As you grow, if the need arises, you can buy other, more expensive equipment: a microscope, laboratory block power supply, infrared soldering station, bottom board heating station, ultrasonic bath, laminator, autoclave, etc.
And this means that it takes longer to warm up the microUSB connector, and, consequently, the printed circuit board. Because of this, it can warp, it can swell, exfoliate. Complicating matters is that there are miniature SMD components nearby, such as resistors and capacitors, and sometimes an optical sensor or SMD LED. If exposed to excessive heat, these components may melt and become unusable.
To lower the melting point, the Rose alloy is used. Before dismantling the connector, all its contacts and soldered areas are "diluted" with a drop of Rose's alloy using a conventional soldering iron. Thanks to this, the solder at the soldering points begins to melt at a lower temperature, and, therefore, we can quickly heat it up with a hair dryer and dismantle it. In this case, neighboring elements and printed circuit board don't get very hot.
Also, the Rose alloy will help out, for example, when installing a new digital microphone on the board. The fact is that a digital microphone is a rather sensitive component and is terribly afraid of overheating. Therefore, you can solder it to the board using the Rosé alloy.
This alloy is expensive, but the good news is that it lasts for a long time. If you decide to save money and buy it on Aliexpress, you will quickly be disappointed, because it is not sold there.
To protect neighboring elements from melting and slipping when soldering with a hairdryer, they can be covered with heat-resistant tape (aka polyimide or kapton).
It is used to protect plastic elements from melting and fix SMD components when soldering with a hairdryer or an IR station. It is often used in smartphones and tablets themselves to isolate and fix structural elements.
A copper braid is required to remove excess solder. Without it, it is sometimes very difficult to remove its excess or solder jumpers between the contacts of the microUSB connector.
Copper braid can be purchased from AliExpress, where it will cost you less, and there is more choice than in retail or chain parts stores.
To install or "glue" touchscreens, you can use different adhesives (B7000, E8000, T-7000). In my practice, I use B-7000 glue. It dries quickly and is easy to "soften" with a slight heat, if suddenly something went wrong and the touchscreen needs to be re-glued.
It is very convenient to use side cutters to dismantle faulty microUSB connectors. best choice there will be high-quality side cutters of well-known brands. Enough for a long time I used Pro "sKit 1PK-717 pliers. They are quite good and inexpensive, suitable for working with electronics. Unfortunately, everything that is harder than copper is too tough for them. Their tips break off and dismantling small elements with such pliers becomes a real punishment .
After some time, I decided to buy a better instrument. The choice fell on the side cutters KRAFTOOL KARBMAX 22018-5-13 with tungsten carbide inserts. At that time, their cost was 1600 rubles.
These are expensive and professional German side cutters designed just for working with electronics and precision mechanics. According to sellers, these are very often bought by those who repair smartphones.
