3. WHAT IS SOLDERING? Soldering is the process of joining metal leads, creating a mechanical and electrical bond. www.engineersportal.in

4. WHAT IS REQUIRED?  The tools needed for the soldering process:  Soldering iron  Solder  Sponge  Flux  Solder wick www.engineersportal.in

5. The main soldering tool Used to melt solder www.engineersportal.in

6. Metal “glue” used to join together metal parts Contains flux Made of Tin and Copper, sometimes Lead www.engineersportal.in

7. Used to clean off soldering iron tip Can be made of various materials Should be used every time before soldering a joint www.engineersportal.in

8. Makes solder melt easier Always use extra flux for rework www.engineersportal.in

9. Use to remove solder Careful, it gets really hot! www.engineersportal.in

10. -Turn on the soldering iron -Set the temperature control on the soldering iron to a temperature less than 700 °F and greater than 450 °F. - As a general rule use a temperature in the range between 550 and 650 degrees Fahrenheit. www.engineersportal.in

11. -Tin the tip of the soldering iron by melting an inch or so of solder on the tip. -The iron will now look shiny on the tip. -Then wipe any excess solder on the golden sponge. -Now place the iron back into the holder. Tinning your soldering iron in this manner will aid in future soldering. www.engineersportal.in

13. Caution: - Soldering is dangerous if not respected - Be mindful of where you are and where the soldering iron is - Eyes and liquid solder www.engineersportal.in
