Soldering is a fundamental skill for any sort of electronics work, and this class will teach you how to safely solder components onto a circuit board.
We’ll give you a small electronics kit — depending on skill level — and you’ll solder LEDs, resistors and other components onto a circuit board. When you’re done, you’ll know how to solder and have a pretty kit to take home!
It is important to work in a clean environment with enough room to complete the task. Wear glasses and don’t breath the fumes while working. Remember the Soldering Iron is very hot and can burn you if you’re not being careful. Be attentive of your surroundings as they can get in the way.
What is Soldering?
Soldering is the process of joining two or more electronic parts together by melting solder to create a bond. Once the solder cools the metal alloy will create a strong electrical bond between the parts.
What is Soldering Iron?
A soldering iron is a hand tool used in soldering. It supplies heat to melt solder so that it can flow into the joint between two work pieces. There are various types of soldering irons and even various tips to make the work process easier.
What is Solder?
Is a fusible metal alloy used to create a permanent bond between metal work pieces. Solder must first be melted in order to adhere to and connect the pieces together after cooling, which requires that an allow suitable for use as solder have a lower melting point to prevent damage to the work piece.
Alloys of lead and tin were commonly used in the past and are still available; they are particularly convenient for hand-soldering. Lead-free solders have been increasing in use due to regulatory requirements plus the health and environmental benefits of avoiding lead-based electronic components. They are almost exclusively used today in consumer electronics.
Tips and Tricks
The tip while working will become oxidized and will not create a good bond with the work piece. You must clean the tip either with a brass sponge (recommended) or a wet sponge.
The joints above are not done properly with various problems. Most of these are caused by the iron not being hot enough or the technique used to make the joints. A good solder joint will be clean and cone shaped.
