Soldering a Surface Mount Resistor
There are several ways to successfully solder SMD components on a circuit board. Some are easier to learn, and some require using special materials (like solder paste, which is a mixture of powdered solder and flux) or special equipment (like SMD solder stations). Actually, you don’t need fancy equipment to do SMD soldering at home. You can easily do it with a soldering iron.
Soldering a resistor is the simplest way for freshmen. At the beginning, you should apply flux to one pad on the circuit board in order to clean the pad and make it easier for the solder to fasten properly. And then touch the circuit board pad with the tip which covers some solder to let them pass on to the pad. Next, place the resistor on its ideal location, and fix it by soldering. The resistor should now be fastened on one side. Apply solder to the soldering tip again and touch the iron tip on the other side. Finally, you’d better to use a loupe to check the solder joints to make sure the connection is good.
