The iron head is used for welding the main parts of the electric iron on the use of the. Soldering iron head has many kinds, such as internal heating type soldering iron head, external thermal jerdonii, thermoregulation type electric iron, double temperature type electric soldering iron, Ceiling Tin type electric soldering iron. The tip of each category of all have different characters and effects. Today we talk about the iron head in the solder machine work is how to use the.
1, select the appropriate solder, to pay attention to the selection of welding electronic components used in the welding of tin wire.
2, the flux is generally used in 75% of the 25% rosin dissolved in alcohol.
3, use the electric iron to tin, the electric iron heat until just to melt the solder, coated with flux, solder and then evenly coated on the soldering iron head, iron head even eat a layer of tin.
4, welding method, the polishing pad and clean element pins with fine sandpaper, coated with flux. With a soldering iron head dip take just the right amount of solder, contact pads, solder joints to be all melting and immersion element lead head, soldering iron head along the components of the pin and gently to a left solder joint.
5, the welding time should not be too long, otherwise easily burnt components, when necessary tweezers grip the pin can be used for radiation.
6, solder joints should be a sine wave crest shape, the surface should be bright and smooth, Wuxi thorn, the amount of tin is moderate.
7, after completion of welding, to use alcohol to circuit board on the residual flux cleaning clean, to prevent carbonization and the flux affect the circuit work normally.
8, the integrated circuit should be finally welding, soldering iron to reliable grounding, or power after the use of waste heat welding. Or the use of an integrated circuit socket, solder socket and then plug into the integrated circuit.
9, the electric iron should be put on the iron frame.
