Hello iraq_mosul

To make fine soldering you need:

1. a very thin nose on your soldering iron that may be less than a millimetre at the end
2. a very steady arm
3. lot of passion
4. lot of exercise
5. and a fine piece of soldering

That's all you need to make a succesfull fine soldering.

Alternative to the fine nose you can take a piece of copper wire and turn it over the current nose of your soldering iron. Then you will solder with the end of this wire.

Another tip I will add:

(1) Use liquid solder flux on the pins before you solder. You can clean them later with alcohol. It will leave a nice clean connection and cause the solder to flow faster.
(2) If you get solder between the pins causing a short, use solder wick to absorb the excess solder. Flux will also help this to go faster and cleaner.

Any idea WHERE we can find this liquid solder flux ? Any common brands ? It is a very good idea after etching, it makes the pcb looks really professional.

Here are some choices:

I am only familiar with the rosin flux and that has been the industry standard for years. But there are several types such as easy clean up types. These might be better if you do not want to use alcohol to clean afterwards. Some are water clean up but I have an opinion about putting water on my circuit boards before they are protected. ;D
