Soldering is process of joining two metals together with soldering iron by the use of a solder to form a dependable electrical joint.
This is a basic soldering guide for beginners about hand soldering with a soldering iron. I hope that it will be good help for most of your DIY projects from electronics. If you are experienced in soldering, your comments are welcome in "comments" area.
In this instructable I will cover the following topics:
- safety precautions before we start soldering operation
-choosing appropriate soldering iron and solder
- preparing for soldering
-inspection of solder joints
• Soldering should be performed only in a well-ventilated area.
• Use smoke absorber
• Soldering iron is very HOT (for most of soldering operation temperature of iron is 350 -400 degrees Celsius). Never touch tip of the soldering iron with your hand.
• Never leave your hot iron down on anything other than an iron stand.
• Keep flammable liquids and materials (such as alcohol, solvent etc.) away from the work area.
• Wear eye protection.
• Do not cut off a grounding prong on an iron plug to make it fit an ungrounded receptacle.
• Hold wires to be heated with tweezers, pliers or clamps to avoid receiving burns on your fingers from objects that are heated.
• Wear ESD (Electro-Static Discharge) protection if you are going to solder electro-static sensitive components such as CMOS components. For most of DIY projects it will be good enough to wear ESD wrist straps (shown on the picture below).
• Wash your hands with soap and water after soldering.
