How to use the iron work properly
1， the appropriate choice of solder， solder wire should be used in low-melting solder electronic components used in welding time not too long， otherwise easy to scorch element， if necessary， forceps pins help dissipate heat.
2， to electric iron on the tin before use， the specific method is: the electric iron pan， to be just to melt the solder， flux coated， and then evenly coated solder iron head， so that the tip even eat a layer of tin.
3， welding method， the pin pad with fine sandpaper and components polished clean， coated with flux. Moisten the tip with solder contact pads， the solder joints on the whole to be melted and
After immersion component lead head， electric iron head pin components along gently lift up left pad.
4， should be a sine wave solder peak shape， smooth surface should be bright， Wuxi thorn moderate amount of tin.
5， after the welding is completed， the residual flux with alcohol to clean the circuit board to prevent flux carbonized affect the circuit to work.
6， electric iron soldering iron should be placed on the shelves， after using the solder tip must be added to prevent oxidation of iron head， affecting the next use not stick tin.
Iron for the first time have to take the micro heat pipe tobacco case. This is normal. Please be assured
