If you touch the tip, you will let go very quickly!

We use the soldering iron to melt the solder and make electrical connections.

When the solder heats up, the rosin melts almost immediately

This is solder.
It is made of metal,Usually tin and lead.

The ROSIN flows around what you want to solder, cleans the metal, and helps make a good solder connection.

The best solder for electronics has

rosin core and is 60% tin, 40% lead.

Safety tip #2

(of 3):

Lead is poisonous. It gets on your skin when you hold the solder, so wash your hands after soldering!

There are other types, forinstance lead-free solder, but it has toxic chemicals in its core, and it is not quite as easy to use as solder with lead. It also corrodes soldering iron tips quickly. If you can only get lead-free solder where you live, it’s OK, but please don’t breathe in the nasty smoke.

for your entire life. if enough collects there then you go insane, and you lose all of your friends. So - wash your handsafter soldering, and keep your friends!

If you don’t wash your hands after soldering, the lead may get in your body, where it gets stored in your brain

For a circuit to work

anything that er, and should not be connected

If you look carefully at the PCB, you will see lines connecting pads together with other pads – these lines are called traces.

All of the parts have wiressticking out of them:

Most pads have a hole in the middle – this is where the lead pokes through and makes a connection to the circuit!

(pronounced “leedz”)

All of these wires, regardless of what they look like, are called

leads

since they lead to the parts.

We’ll start with a

resistor.

So, to solder in the resistor, you start by finding the correctvalue of resistance from the project’s documentation.

Resistors have two leads and (unlike some parts, such as diodes, which have a “plus” side and a “minus” side) can be placed in their pads in either direction.

Then bend the two leads of the resistor down the width of the part, like this: Then place the two leads through the two pads on the PCB for this resistor.
You push the resistor’s...
