Say you want to create a social network for soccer moms to chat and commune. Instead of building up the social site first and relying on the 8 soccer moms you know to get it going, it's better to create a blog with tips targeted toward soccer moms. Build it up with stories and useful tips other soccer moms need.
The main composition of a soldering iron is a metal tip, which is heated in an insulated handle by either gas combustion or electricity. Today, electronics soldering iron is widely used in repair jobs, installations, electronic assemblies and so on. It is also used for pyrography as well as plastic welding, although very rarely seen.
The soldering iron tip transfers thermal energy from the heater to the solder connection. In most soldering iron tips, the base metal is copper or some copper alloy because of its excellent thermal conductivity. A tip's conductivity determines how fast thermal energy can be sent from the heater to the connection. Both geometric shape and size (mass) of the soldering iron tip affect the tip's performance. The tip's characteristics and the heating capability of the heater determines the efficiency of the soldering system.
