SOLDERING
Soldering is the method we use for joining electronic components together. Solder is metal alloy of tin (60%) and lead (40%), that becomes molten at around 200°C. Solder contains flux that helps the joint form correctly.

Safety · // YOU SHOULD ALWAYS SOLDER IN A WELL-VENTILATED AREA. // · // DO NOT INHALE THE FLUX SMOKE. // · // TAKE CARE NOT TO TOUCH THE TIP OF THE SOLDERING IRON ON THE CABLE OR YOURSELF. //

Method 1. Collect all the tools and equipment together. 2. Make sure that the sponge on the stand is damp. 3. When the soldering iron has reached its temperature (around 450°C) clean the tip on the sponge. 4. Place a small amount of solder on the tip of the soldering iron. This is called tinning and helps the transfer of the heat from the soldering iron to the components. 5. Place the soldering iron against the track and the leg of the component and hold it there for a few seconds. 6. Touch the solder against the track and leg of the component so that just enough solder runs onto both. 7. Remove the solder and then the soldering iron and allow the joint to cool before you attempt to move it. 8. Cut off any excess leg from the component just above the top of the soldered joint.
