DIY phone connector repair

In detail: do-it-yourself repair of the phone connector from a real wizard for the site my.housecope.com.

Hello everyone! Today I will talk about replacing the USB connector on the tablet. This replacement is unusual in that it had to be replaced with an ordinary soldering iron, without a soldering station. It all started with the fact that I was far from home, in a neighboring town. Friends, having learned that I was a radio amateur, immediately asked for help in repairing their devices 🙂 The first was a tablet with a loose USB connector, which did not even want to charge the tablet, it will be discussed here. To begin with, it was necessary to consider dismantling the broken connector, since it is very easy to damage the printed circuit board, especially with an ordinary soldering iron. It was decided to bite through the old connector with needle-nose pliers, and you need to bite through the upper end of the connector. But first, let's take a look at our “patient”. Remove the back cover:

In this tablet, it turned out to be latched, and under it is already the main aluminum cover, we see a bunch of screws, I have already unscrewed them above in the photo.

We look very carefully, have we forgotten some bolt, unscrewed everything that might prevent us from removing the back cover? - Okay, let's take it off.

Now you need to remove the board itself from the top of the tablet. The main thing is not to rush, otherwise we can break something, we check how and with what the board is attached to the tablet, in this tablet - on bolts and latches. Unscrew the bolts.

We disconnect all the connectors and cables from the board, in order to disconnect the cable, you just need to lift this connector clip up and pull the cable towards you:

Disconnect the display connector from the board, this tablet uses the connector as on laptops:

All the bolts were unscrewed, all the cables were disconnected, now you can remove the board for further manipulations.

We take it out carefully, as there are parts on the SMD board, and planar microcircuits, which are soldered only with a soldering hairdryer. And if SMD output parts and microcircuits can still be soldered with a soldering iron, then BGA only with a hairdryer. We carefully pry on the latches that hold the board, you need to pry with something soft, for example, I use an ordinary SIM card for this, or a bank plastic card. By the way, they also disassemble the plastic panels of all kinds of gadgets, since it is impossible to disassemble plastic cases with metal tools - it is very easy to damage or even break them. Here is the board itself:

You can start dismantling the broken connector, as I wrote above - my tool is far away, but I need to do it. We begin to bite through the old connector with needle-nose pliers, as shown in the photo below:

We open it very carefully, by bending up and down we break off the contacts so that the pieces of the pins remain on the contact pads of the board, the contacts themselves cannot be bitten off with needle-nose pliers - they will fly off the board along with the tracks. We can safely solder the rest of the connector and contacts.

In the photo, the contacts are not undermined, I just used a lot of tin for desoldering. Remove excess tin with copper wire or braid, clean and solder a new connector in place.

We solder it well, the connector pins were soldered with an ordinary 25 W soldering iron, and the connector itself was soldered to the board with a 40 W soldering iron. After checking for operability, we clean it from the gumboil and twist the tablet in the reverse order, observing accuracy.

It is worth soldering only with high-quality soldering irons, the heaters of which must be well insulated from the tip itself and the metal parts of the soldering iron itself. The soldering iron should not break through at all, and accumulate static electricity, so the breakdown of the soldering iron threatens, at best, with the failure of the soldered device, and at worst.Guess it yourself 🙂 Static electricity is dangerous to semiconductors: sensitive parts may break.

That's it, the replacement of the connector was successful, the repair is over. As you can see, even in the absence of the necessary tool and a lot of experience, a lot is possible in terms of restoring gadgets with your own hands. Until next time, dear readers. Especially for the site "Radio circuits" - BIOS.

How to solder the micro usb connector on a tablet, phone, netbook, laptop with your own hands?

Now in devices you can often find usb connectors (u-es-bi, English Universal Serial Bus - "universal serial bus"). Due to accidental mechanical damage, for example, while the device is in charging mode, such a malfunction is often encountered - such as a break in the micro usb connector. You will learn how to solder the micro usb connector yourself in the article below.

If you love tinkering and know how to handle a soldering iron, then it will not be difficult for you to re-solder the micro usb connector on the tablet yourself. To do this, we need tools: a 25 watt soldering iron, solder, easy fusible tin, tweezers, a small curly screwdriver, a scalpel or a knife with a thin blade, a magnifying glass.

The most important thing is that we do everything carefully and accurately!

For disassembly, we need:

Screwdriver Set;
Tweezers;
Scalpel or knife;
Soldering iron.

Step 1. Unscrew all the fastening screws on the tablet or phone, carefully remove the back cover with a knife or scalpel, thereby freeing the case latches from the grooves, tilting the blade towards the screen.

Step 2. After removing the cover on the tablet (phone), you need to ground the soldering iron, solder the wire to the common body (minus) and then the other end of the wire to the body of the soldering iron itself. This must be done in order to protect the tablet from accidental static electricity, which can damage its electronic components. You should also make an antistatic wrist strap and also ground it.

Step 3. Next, we solder the wires from the battery, this is necessary in order not to accidentally close the electronic circuit and not to damage the components.

Step 4. After that, we unscrew all the fastening screws on the board and turn it over, thereby we get directly to the micro usb connector itself.

Next, I give a short list of micro usb connector malfunctions and how to fix them:

If the connector has become unusable and its further repair is impossible, then it should be replaced. To do this, we need to find a knowingly working one, you can use an unnecessary or faulty cell phone and unsolder the micro usb connector from the phone. To do this, take a scalpel and push it between the board and the connector, heating the mounting tabs of the micro usb connector, gradually lifting one side, then the other. Further, after the mounting tabs are soldered from the board, you need to take tweezers, since the connector heats up quickly, you should not overheat, because the plastic parts of the micro usb connector can melt and deform. After that, we unsolder the connector pins, they should be heated all at the same time. Pay attention to the installation, smd parts can be near the connector and if soldering is not neat, they can be soldered or burned, be careful and therefore the soldering iron tip must be thin. The sequence for unsoldering the connector is the same and dismantling the micro usb connector on the tablet should be done in a similar way.

In this case, you should pay attention to the integrity of the tracks themselves, for this we take a magnifying glass and inspect the installation, if the tracks are intact on the board, then well, if not, then you have to restore them. It is necessary to find all the ends of the torn off tracks and carefully clean them with a scalpel (clean the varnish), then tin with a soldering iron.After that, we take the micro usb connector itself and solder the fastening tabs of the connector to the board, I advise you to pre-glue the connector to the board before soldering, this will reduce the likelihood of repeated breakage. Remaining small, solder the leads, if the tracks are intact, then it will not be difficult, but if not, we do the following: we take thin copper wires (one hair of a stranded thin wire) and solder between the leads of the tracks and the connector. If for some reason it was not possible to restore all the tracks (the track under the electronic part is cut off and there is no way to track its location). In this case, it will be possible to do only for charging the tablet, while we need to restore only two tracks, two extreme outputs to the micro usb connector, the only drawback is the inability to connect the tablet to a computer and external devices.

Or just wind the copper wire around the tip and use it as a thin tip, in common people: "Quickly mini-soldering iron"!

It is advisable to buy a cheap power regulator for lamps, with which you will regulate the temperature of the sting so that the rosin on the sting does not quickly turn into carbon deposits, so as not to overheat the conductive tracks and so that they do not fly off.

Lamp power regulator

You can, of course, without a power regulator, but then you have to solder with short-term touches so as not to overheat the tracks and boringly often cleaning the sting from black rosin oxides. And again - and this is the art of the possible, on the verge of risk. Decide for yourself.

After that, be sure to check how you soldered, whether everything looks beautiful, whether something sticks out, whether there is a so-called. "snot" between the contact pads, as this can cause a short circuit and is fraught with a more serious breakdown of the device. Use a little braid, if the sting cannot remove the nozzle, it will take away the excess solder, and the tin will squeeze out under the leg of the nest. If, nevertheless, a little remains, then lubricate the place with rosin and lightly tear off the remains of tin between the contacts with a sting. But do not overdo it, the solder should be in the form of a sufficient droplet covering the contact for a firm contact. Do not spare the flux (rosin) so that the soldering is electrically conductive (and not the so-called "cold" or "dry" soldering, not conductive).

Now, partially, without screws, we assemble the smartphone, connect the cables, turn on, check for operability, if everything is fine, charging is in progress, the battery shows that it is accumulating charge, then we finally assemble it by screwing and closing the rear decorative cover.

For clarity of the process of replacing the nest, I cut gifs for you from the video of a professional's work. Watch and listen.

Nowadays, it is hard to believe that mobile devices were the easiest way to connect with other people. Now an ordinary mobile phone has turned into a high-speed smartphone with huge multimedia functionality, and the body has begun to store the power of a good computer inside itself. The use of devices is very addictive and some do not even take a break, even for a short time. Such exploitation greatly affects charging, and constant recharging can lead to damage to one of the most important connectors of the phone. How to fix the phone charging jack if it breaks down, you will learn from today's article.

How do I fix the charging port on my phone at home? Here you need to figure it out, then everything will work out. Inaccurate use of a mobile device very often ends in some kind of breakdown that needs to be fixed. Sometimes the breakdown lies in the power cable connector. In this case, you need to find out how to fix it, and for this it is worth familiarizing yourself with the main causes of the defect.

You can spill some liquid on the device or just drop it well to disable this module.
Constant mechanical stress deforms the socket, which can make charging the gadget simply an impossible procedure - the plug will not fit into the socket or it will dangle in it.
Contact pads may also bend, which will completely block access to electricity.

Let's talk right away about the worst thing - about moisture.

Moisture contact of a mobile phone connector is the most dangerous damage. Corrosion will start a chain reaction and all nearby components will oxidize. Such defects can also damage the dynamics, which is most often located at the bottom of the device. Also, the speaker itself gives access to moisture to get on the cable or connector. Therefore, even light rain can damage your phone.

Important! Find out what you can do, is it possible to reanimate the gadget if a more serious trouble happened to you - the phone fell into the water and does not turn on.

The most important thing is to assess the complexity of the damage, since not all cases allow you to repair a house. The best option is to use the services of a qualified specialist from some service center. So you will not risk breaking your device.

Very rarely, restoration work can be carried out independently. It is best to find an alternative way of charging for a while, until you decide for yourself whether to fix it yourself. While the required amount is being set aside for repairs in the workshop, read the instructions for charging a phone with a broken socket:

Insert the charger into your smartphone and plug into the network.

Important! This method is relevant only for devices that have suffered from mechanical stress, and not from moisture.

Gently wiggle the cord and device in opposite directions. You may be able to close the contact and charge the device.
If the mobile phone still detects the presence of a charger, then it is worth fixing the position found. Books and other items can be used that can set the phone so that the power continues.
Before carrying out all these actions, it is worth making sure that the problem is in the socket, and not in the battery. Prolonged use of the phone leads to the fact that it no longer holds a charge. For this case, you will have to acquire a new battery, and not deal with a "phantom" breakdown.
If it's all the same in the nest, then repairs here cannot be avoided.

Important! Remember that all these manipulations can further loosen the nest, so do not use too much force during work.

If everything is in order with the connector now, but the problem of the lack of energy in the battery still has not disappeared, read on what to do if the phone does not charge from charging.

If your phone is designed to allow you to remove the battery, then you can use the universal charger. Such devices are called "Frog". It costs, of course, not very cheap, but sometimes you need to urgently charge the phone. This gadget has special grooves into which you need to insert and fix the battery.

But this method also has a number of obvious disadvantages:

While charging, the smartphone will not work and cannot be used until the battery is charged.
The purchase price of "Frog" is quite high and does not always justify its purchase.
If the reputation of the manufacturer is very dubious, then you will only harm your device.

How do I fix my phone's charging connector? You can try to replenish energy reserves by disconnecting the power port itself from the phone.

Important! This method is very complex and requires the user to have basic knowledge and skills in working with equipment and electricity.

The essence of the work is as follows:

We remove the battery from the smartphone.
We unplug the charger from the outlet, arm ourselves with a sharp object and remove the insulation from the wire by five centimeters.
Strip the wires and determine where the plus is and where the minus is.
Determine the polarities on the battery and connect the wires to it.
Secure the improvised terminals and apply mains power.

Important! This method is not recommended as you may get hurt even while charging. Do not work with uninsulated wires if you have never done so and do not know how the electric current behaves.

You need to be very careful if you do decide to fix the charging jack with your own hands.

To disassemble the case and remove the socket, we need:

A small set of screwdrivers.
Technical tweezers (regular tweezers will work as well).
A utility knife or a regular sharp one.
Soldering Station.

Now you need to do the following:

We unscrew all the screws on which the case is attached.
Carefully remove the cover by prying it off with a clerical knife.
We ground the soldering iron, solder the wire to minus (device body). The other end of this wire must be brought to the body of the soldering iron itself.

Important! These measures are necessary so that the mobile phone does not suffer from the accumulation of static electricity, which can harm parts. It's also a good idea to make an ESD wrist strap and ground it.

Now we unsolder all the wires from the socket. This is to prevent short circuits.
Next, you need to remove the screws from the board that hold it. Now we have access to the microUSB connector.
We take out the old socket, solder a new one in its place, assemble the device in the reverse order and check it for operability.

In this article, I will tell you how to properly change the charging socket on your phone or micro USB tablet. This method has been developed over the years, and in my opinion is the fastest and most reliable.

Active soldering flux or a weak soldering acid, you can also use aspirin tablets, just be careful of the caustic smoke.
I buy flux RMA-223 in syringes here: https://ali.pub/lqw23
Any soldering station with a hair dryer and a soldering iron.
Suitable micro usb connector.
Tin in a coil, preferably 0.3mm, take here: https://ali.pub/mieuo
You can buy tweezers where I get them.
Well, everything seems to be

And so we disassemble the phone or tablet, take the board with the charging socket and fix it, for fixing I use the board holder I bought here: https://ali.pub/4lstm

We fix it so that the contacts of the back of the connector are on top, then we apply flux for soldering rma-223 to all contacts of the connector, turn on the hairdryer at the soldering station with a set temperature of 330-350 degrees Celsius. And yes, I almost forgot if there are plastic parts next to the charging socket, for example, a camera, or a microphone, they need to be protected from high temperatures, for this I use heat-resistant foil, I took it here: https://ali.pub/905dy

We leave only the charging connector not covered with foil and begin to warm it up with a hairdryer, so that the entire area of contact with the board warms up, I make quick circular movements and after about a minute, one and a half, the socket is easily removed from the board with tweezers.

Next, we need to prepare a new charging socket, for this we process all the contacts with an active flux and solder the contacts with a soldering iron. After soldering, the connector needs to be washed from the active flux; for washing, I use the "Kalosha" liquid, which is sold in hardware stores. After that, the charging socket is ready to be installed on the board. We warm up the installation site and use tweezers to carefully install the new connector, heat it until the connector contacts on the motherboard are covered with tin and the socket falls into place.
