Virtues of lead-free solder wire

? Solder joint is bright and firm. 
Short wetting time, fine weld ability. 
Don't splash the rosin during welding. 
Rosin in the wire is distributed evenly and  shows fine continuity.
Little dross of welding head.
Solder wire can't be snarled when it performs routing automatically.
Wire coiling appears trim, nice and polished. 
No smell, little smoke, without volatilizing gas harmful for healthy. 

Lead-free solder wire soldering technology

? Hand Soldering and Rework.
Iron tip temperature should be higher  than  400℃.
To avoid excess heat input, swifter action with the iron is required, and this implies significant operator retraining.
Iron tip life will be shorter.
