25w soldering Iron – Chisel Tip
- A soldering iron is a hand tool used for soldering.
- It supplies heat to melt solder so that it can flow into the joint between two workpieces.
- A soldering iron has a heated metal tip and an insulated handle. Heating by passing an electric current (supplied through an electrical cord or battery cables) through a resistive heating element. Cordless irons housing combustion of gas stored in a small tank, often using a catalytic heater rather than a flame.
- Present day people are not using Simple irons less commonly, in the past were simply a large copper bit on a handle, heated in a flame.
- Soldering irons are most often used for installation, repairs, and limited production work in electronics assembly. High-volume production lines use other soldering methods.
- Large irons may be useful for soldering joints in sheet metal objects. Less common uses include pyrography (burning designs into wood) and plastic welding.
- It is of different types, like
- Cordless iron
- Temperature-controlled soldering iron
- Soldering station
- Soldering tweezers
- Hot knife
- The best technique for soldering is simple, so repeat this mantra: Heat the metal, not the solder.
- For example, you heat the metal of a component pin and the metal of a circuit board pad simultaneously, and then you touch the tip of the rosin-core solder to the pad or the pin, but not to the iron.
- If you have sufficiently heated the two metals (the pad and the pin), they will heat the solder, which then flows quickly to both the pad and the component pin.

TIPS FOR SUCCESSFUL SOLDERING
- Purchase the correct solder type and width, as well as the correct soldering iron and tip. Think small tip and thin solder.
- Some soldering kits include training materials to help you master the art of soldering. Although people can tell you how to solder, good soldering requires hands-on experience. Take the time to solder a few cheap test components into a test prototype board to get your technique down before using your skills on somewhat more costly electronic parts.
- If your solder looks like a clump of wadded-up aluminum foil, you’ve soldered it incorrectly. The solder should look smooth and shiny and must cling to both items (for example the component pin or wire and PCB pad) to make a good connection.
- Be careful not to apply your soldering iron for long periods of time. Otherwise, you can damage sensitive components or burn up a circuit board trace. You should solder quickly so that your components or trace don’t stay hot for too long.
- You should always make a mechanical connection before making a solder connection. For example, check to make sure the component pin actually touches the wall of the pad hole before you solder it. This will ensure that your soldering goes quickly and smoothly and will help to keep a solder joint from “bridging” to the pin and separating.
- You may want to flux before soldering to get a cleaner solder. Flux is a pasty, greasy, oily substance that helps to clean the metallic surfaces being soldered. It also helps you produce smooth solder joints that adhere well to pin and pad surfaces.
- Only experience will tell you if you ha
