Brazing is a method of joining metals with another, more low-melting metal. As a rule, for soldering circuit boards in electronics, solder is used, which contains 60% tin, as well as 40% lead.
Necessary
- - soldering iron;
- - small sponge;
- - solder;
- - pliers;
- - tweezers;
- - side cutters.
Instructions
Step 1
Prepare your soldering iron before soldering the board. Plug it in, moisten the sponge with water. After heating the soldering iron, cover the tip with solder, then wipe it with a damp sponge. Wipe it periodically while you work. Prepare the radio component before soldering.
Step 2
Bend the pins so that they fit into the holes in the board. This can be done with pliers. Then insert the part into the holes. Observe the polarity of the parts when doing this. Spread the leads on the other side of the board to prevent the part from falling out of place.
Step 3
Bring the solder and soldering iron tip to the mounting point at the same time. Touch the tip to both the output to be treated and the board. Do not change the position of the soldering iron tip until the solder covers the entire contact surface with an even layer. This time will depend on the temperature of the soldering iron, it can be from half a second to a second. This time is enough to heat up the soldering point of the board.
Step 4
Circle the tip of the soldering iron around the contact in a semicircle, while moving the solder in the opposite direction. Apply about a millimeter of solder to the soldered area. The place should be hot enough for the solder to melt and spread throughout the pad. Pull back the wire of the solder after applying it to the soldering area. Move the tip of the soldering iron away from it with a quick movement so that the solder takes its final shape and solidifies.
Step 5
Solder the microcircuit to the board. To do this, solder the circuit to the adapter using the two diagonal pins. At this point, pay attention that the pins of the microcircuit are located exactly above the adapter tracks. When you have achieved this, cover the leads with plenty of solder. Remove excess solder with a wire.
