Soldering Your First Component

Let's put all these tools into action. This first video will go over the basics of soldering your first component -- headers!

Check out the Vimeo version here.

It's really that easy! Follow Dave's simple rules to make every solder connection a good one.

Be cautious when handling hot irons
Use third hands or vices to hold boards while you solder
Set your iron at a good medium heat (325-375 degrees C)
If you see smoke coming from your solder, turn down the heat
Tin your tip with solder before each connection to help prep the joint
Use the side of the tip (aka the sweet spot), not the very tip of the iron
Heat both the pad and the part you want to solder evenly and at the same time
Pull the solder away, then the iron
A good solder joint should look like a volcano or Hersey kiss, not a ball or clump

We've also put together this digram to help you better understand what makes a good solder joint.
