What is soldering and desoldering techniques?

A typical printed circuit board, or PCB, contains a large number of electronic components. … Soldering and desoldering is performed to install a component on a PCB or to remove it from the board.

Do you need flux to Desolder?

When desoldering, you should apply flux to whatever the solder is supposed to wet to. If you are using a copper desoldering braid, then apply a bit of flux to it.

What is a desoldering tool?

A desoldering pump, colloquially known as a solder sucker, is a manually-operated device which is used to remove solder from a printed circuit board. There are two types: the plunger style and bulb style. (An electrically-operated pump for this purpose would usually be called a vacuum pump.)

How do you Desolder without a desoldering tool?

Use something called solder wick. Its a rosin flux impregnated fine copper braid – comes in several widths but it will wick the solder out of joints. Usually cut the leads of the component being removed, heat and pull the leads out, then use the wick to absorb the solder out of the holes.

Do you have to remove old solder?

Why is desoldering important?

Desoldering involves the fine removal of solder and parts mounted over the circuit boards. It involves great significance in the electronic manufacturing industry in order to desolder the components as well. Desoldering tools are of great importance in domestic, commercial and the industrial applications as well.
