N2 gas and preheating effect improves the solderbility greatly!
N2 System Set Example,
Soldering Station HAKKO FX-951,
N2 Soldering Iron HAKKO FM-2026,
N2 Gas Generator HAKKO FX-780,
N2 Flowmeter HAKKO FX-791
If in trouble because of the poor solderbility of lead-free solder, HAKKO N2 System can be brought to the settlement. (Click here for set example.)
1. Preheating effect
The preheating effect is achieved by passing Nitrogen gas along the heating element in the hand piece.Soldering can be done on multilayer PWB and high density PWB sensitive to heat without raising the temperature of the tip excessively, even when the melting point of lead-free solder is high.


2. Improvement of wettability and spreadability
By using the HAKKO N2 System, the wetting and spreading are excellent for eutectic solder, lead-free solder and high-temperature solder, comparing with our conventional soldering iron. This feature prevents failed soldering due to bridges while producing great effect on repair works.

3. Preventing oxidation
Oxidization of solder and soldering tip can be prevented by using Nitrogen gas, which passes along the nozzle ass'y uniformly.
