Desoldering tool
Soldering Iron
Soldering lead
It is a metal alloy usually made of tin and lead which is melted using a hot iron. The iron is heated to temperatures above 600 degrees fahrenheit which then cools to create a strong electrical bond.

This is consider as the first step (A) in a Soldering Technique.
Inspect the joint closely. It should look shiny and with a volcano shape.
Apply a small amount of solder onto the joint.
Hold the soldering iron like a pen, the base of the handle
Touch the soldering iron onto joint to be soldered
This is consider as the fifth step (E) in a Soldering Technique.
Inspect the joint closely. It should look shiny and with a volcano shape.
Apply a small amount of solder onto the joint.
Hold the soldering iron like a pen, the base of the handle
Touch the soldering iron onto joint to be soldered
This is consider as the third step (C) in a Soldering Technique.
Inspect the joint closely. It should look shiny and with a volcano shape.
Apply a small amount of solder onto the joint.
Hold the soldering iron like a pen, the base of the handle
Touch the soldering iron onto joint to be soldered
This is consider as the second step (B) in a Soldering Technique.
Inspect the joint closely. It should look shiny and with a volcano shape.
Apply a small amount of solder onto the joint.
Hold the soldering iron like a pen, the base of the handle
Touch the soldering iron onto joint to be soldered
This is consider as the fourth step (D) in a Soldering Technique.
Touch the soldering iron onto the joint to be soldered.
Hold the soldering iron like a pen, near the base of the handle.
Remove the solder, then the soldering iron, while keeping the joint in still position.
Inspect the joint closely. It should look shiny and with a volcano shape.
This is consider as the fourth step (4) in Removing components in PCB using a Desoldering pump (solder sucker).
The pump will need emptying occasionally by unscrewing the nozzle.
Wait a second or two for the solder to melt.
Set the pump by pushing the spring-loaded plunger down until it locks.
Then, press the button on the pump to release the plunger and suck the molten solder into the tool.
Apply both the pump nozzle and the tip of your soldering iron to the joint.

This is consider as the third step (3) in Removing components in PCB using a Desoldering pump (solder sucker).
The pump will need emptying occasionally by unscrewing the nozzle.
Wait a second or two for the solder to melt.
Set the pump by pushing the spring-loaded plunger down until it locks.
Repeat if necessary to remove as much solder as possible.
Apply both the pump nozzle and the tip of your soldering iron to the joint.
This is consider as the sixth step (6) in Removing components in PCB using a Desoldering pump (solder sucker).
The pump will need emptying occasionally by unscrewing the nozzle.
Wait a second or two for the solder to melt.
Set the pump by pushing the spring-loaded plunger down until it locks.
Repeat if necessary to remove as much solder as possible.
Apply both the pump nozzle and the tip of your soldering iron to the joint.
