What is it for?
• Making good conductive contact between a component and the PCB
• Through-hole parts• Surface mount parts
What do I need?
• Soldering iron• Solder• Flux• Sponge and water
Premise
• Heat up soldering iron• Apply flux• Heat up PCB pad with soldering iron• Hold solder between soldering iron
and pad until it flows• Remove solder and iron, allowing the
joint to cool
Common mistakes
• Using too little or too much solder• Making the iron too hot or leaving
the soldering iron on (can cause damage)
• Not allowing the solder to flow• Trying to remove solder, but ripping
up the traces instead
Sidenote on parts selection
• Do not pick super tiny surface mount parts
• Do not pick parts without pins
Not sure if resistor or dust…
Some tips
• Do continuity checks!• Use flux (only need a little bit)• Take care of the soldering irons• It takes some practice
