Basic tips for using electric soldering iron:
1.Select suitable solder, should choose welding electronic components with low melting point solder wire.
2.Flux, 25% rosin dissolved in 75% alcohol (by weight) as flux.
3.Before the use of soldering iron on tin, the specific method is: the electric iron hot, to just be able to melt solder, coated with flux, and then with solder evenly coated on the soldering iron head, so that the soldering iron head evenly eat a layer of tin.
4.Welding method: polish pads and pins of components with fine sandpaper and apply flux. Dip an appropriate amount of solder with the soldering tip, contact the solder spot, until the solder on the solder spot all melted and immersed in the element lead, the soldering tip along the components of the pin gently lift away from the solder spot.
5.Welding time should not be too long, or it is easy to burn the components, when necessary, tweezers can be used to clamp pin to help heat.
