A simple, beginner-friendly guide to soldering electronics.

Soldering is a fundamental electronics skill - and it’s much easier than it looks. This guide is designed for complete beginners and pairs with Tinker Fox soldering kits.

What You’ll Need

The Basics of Soldering

1. Heat the joint

Place the tip of the soldering iron so it touches both the component leg and the copper pad on the circuit board.

2. Add solder

Feed solder into the heated joint - not directly onto the iron. The solder should flow around the joint.

3. Remove solder, then iron

Once the joint is covered and shiny, remove the solder first, then the iron.

4. Let it cool

Don’t move the joint while it cools. This only takes a second or two.

What a Good Solder Joint Looks Like

If your solder joints look dull, blobby, or uneven - don’t worry. That’s completely normal when learning.

Practice First

Tinker Fox kits include a separate practice board so you can learn without pressure. Your first few solder joints probably won’t be perfect - that’s expected and encouraged here.

Once you’re comfortable, move on to the final project knowing what to expect.
