Soldering:
Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a relatively low melting point. Soft soldering is characterized by the melting point of the filler metal, which is below 400 °C (752 °F).[1]
The filler metal used in the process is called solder.
Soldering is distinguished from brazing by use of a lower melting-temperature filler metal. The filler metals are typically alloys that have liquidus temperatures below 350°C. It is distinguished fromwelding by the base metals not being melted during the joining process which may or may not include the addition of a filler metal.[2] In a soldering process, heat is applied to the parts to be joined, causing the solder to melt and be drawn into the joint by capillary action and to bond to the materials to be joined by wetting action. After the metal cools, the resulting joints are not as strong as the base metal, but have adequate strength, electrical conductivity, and water-tightness for many uses. There is evidence that it was employed up to 5000 years ago in Mesopotamia.[3]
Deaoldring:
n electronics, desoldering is the removal of solder and components from a circuit for troubleshooting, for repair purposes, component replacement, and to salvage components. Electronic components are often mounted on a circuit board, and it is usually desirable to avoid damaging the circuit board, surrounding components, and the component being removed.

It's too good
It's fantastic
It's good post
very helpful....
You may want to check out the tips for soldering in our FAQ section.
Your soldering iron may not be clean, you need to clean off the tip frequently with a damp sponge.
Also the black specs- once dry you can rub these specks off or patina over. Your iron may be a little too hot or you are not moving quickly as you spread.
The bubbles are caused by the iron being to hot- so you may want to turn your solder iron down a bit. I do have a solder video that could be of help to see the visual of this technique- it does take patience and practice.
Keep at it you will get it.
@pult
it is just a basic soldering what i explained here.
