Caution:
- Soldering is dangerous if not respected
- Be mindful of where you are and where the soldering iron is
- Eyes and liquid solder
- Everyone is expected to solder
- If you get burned…
- Stay together, don’t work ahead

Prep Step 4: Tinning the iron
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.

Soldering Tips
Make sure tip is hot
Clean & tin tip
Keep tip clean by using wet sponge and cloth
Heat until the parts are hot enough to melt solder
Hold until solder flashes around pad
Do not put too much solder on

TIPS:
workmanship.nasa.gov
Use caution when clipping leads to avoid flinging metal across the room.
All soldering must achieve a good solder filet on the pad as shown for circuit reliability.
Also clip the leads in this fashion.
Bend resistors and diodes using your plastic tool as shown.
Example of a good solder filet
