Those of you who know a soldering iron and know how to solder electronic components, such as resistors, capacitors, transistors, chips, etc., watch this video where the soldering process can be seen very closely.
In a recent YouTube video Robert Feranec used a good, but very expensive microscope to experiment with different ways of soldering electronic components.
Those of you who have held a soldering iron, tin and soldering iron in your hand usually do not pay much attention to how good a soldering is, as long as it is strong and works properly. But as Robert Feranec points out, it's worth taking a close look at what happens when the solder melts and flows until it solidifies.
The video starts with the most difficult soldering situation, i.e. a ball-gauge (BGA) chip. It also happens to be one of the most difficult techniques to visually assess, both during gluing and afterwards to check the quality of your work.
It then does various tests as well as deliberate mistakes, such as misaligning wires or using too much solder, so you can figure out exactly how the solder is failing. Finally, you will see the welding process both with automatic machines and with classic manual welding.
