Soldering 101 A Really HOT Topic

Soldering • The process of making an electrical connection by melting low-temperature metal alloys around component leads • Soldering is just as much an “Art” as it is a “Science” • We will: – Go over some soldering vocabulary – Illustrate graphically soldering techniques – Solder a few components on the TV Remote board – Complete the board as homework

Soldering Process in Brief 1. Turn on soldering iron and let it get to temperature 2. Clean soldering tip with a damp cloth or sponge 3. Install the component and hold in place with a physical connection 4. Heat the component lead and the adjacent circuit board pad – apply the right amount of heat (art) 5. Touch solder to the component lead and pad - melt the right amount of solder (art) 6. Remove solder 7. Remove heat (art) 8. Hold steady until cool 9. Inspect the connection (art and good eye)
