Soldering is a permanent connection of metal parts using solder. It has become widespread in electronics and radio engineering because of its effectiveness and relative simplicity. You can solder anything you want. Even a faulty phone. Naturally, when soldering a phone, you need to take into account certain rules and nuances, but this is not so difficult as it seems at first glance.
Instructions
Step 1
Determine the cause of the phone malfunction. If it is a connector, it must be replaced. First you need to remove it. A very common problem is overheating of the board or damage to neighboring micro-parts during shooting.
Step 2
Cut the connector legs with a scalpel or utility knife. Do not touch the tracks of the board, otherwise you will have to change them too. Then pull the plastic core of the connector outward by bending the small tabs on the connector housing.
Step 3
Using a soldering iron or nippers, remove the remains of the case, leaving, if possible, two front legs, which are soldered into the board. This is done to make it easier to install the new connector.
Step 4
Using a toothpick or needle, soldering iron and flux, unsolder and slide the remaining separated legs to the edge of the board. Remove them, tin everything with flux and prepare the contacts for soldering. It is recommended to use tin and other more or less strong alloys as solder. Again, depending on what part you need to solder. Solders differ in both melting point and strength, but tin is fine in this case.
Step 5
Use nippers to bite off the two front legs on the new connector (if you left them in the board from the old connector). Place the connector on the board and adjust it to the desired location. Solder the two outer legs to secure the correct position of the connector. When soldering, press the legs to the board with a flat, thin screwdriver.
Step 6
Solder all other legs in the same way. Sparing little tin, solder the connector body and the remaining legs to the board. Use a more powerful soldering iron to prevent the socket from falling off after a week. Reassemble the device in reverse order and check its functionality.
