The next 6 steps will show you how to solder surface-mount components onto a circuit board. You'll need a fine-tipped soldering iron in addition to the following:

Solder wire (leaded or lead-free) or solder paste

Flux

Tweezers and picks to help manipulate the tiny components

A tip cleaning tool (wet sponge or brass wire)

A magnifying glass or lens

A fume extractor (if you're working indoors)

High concentration (>90%) isopropyl alcohol and a soft bristle brush (like a toothbrush)
