Mastering the Art of Soldering
The following is a detailed step-by-step guide in soldering SM components. The contact
point of this component is usually located at the two ends of the component; the two ends
are the points that are needed to be soldered onto the surface of the PCB. To solder, use
the following steps:
1. Apply a small amount of flux to one pad (the pad is where the contact point of the
component will be placed). The purpose of the flux is to clean the area so that the
solder will stick properly.
2. Add a little amount of solder to the pad
3. While warming the solder on the pad, use tweezers to carefully place the component
in position. Hold it steady in place. Tack one side of the component on one pad by
placing the tip of the soldering iron in between the pad (with little solder) and the
component end and letting the solder flow. Add additional solder as needed.
