Quick Overview: Soldering a Resistor

Bend the resistor legs

1) Bend the leads (or legs) at a right angle to the body of the resistor. Put the leads through the holes in the practice area of the PCB (Printed Circuit Board).

2) Flip the PCB over and bend the leads outward slightly. This will hold the resistor in place while you solder.

3) Use blue putty to stick the PCB to the table.

4) Heat both the component lead and the PCB pad simultaneously, then melt solder (and the flux in its core) into the joint, bonding the three metals together. We'll go through step in greater detail on the next page.

5) And finally hold the leads and use your cutters to snip the excess free. Cut the lead, not the solder. If you don't hold them while cutting they will fly and create a dangerous safety hazard, particularly for your eyes.
