Tech Tips

N2 System – improving wettability

  • At first solder flows to the high heated tip end, which is one of the characteristics.
  • Solder flows evenly and smoothly over the copper board when temperature of workpiece reaches solder melting point.
    N2 system warms the workpiece faster by preheating effect.
  • The flux functions of preventing re-oxidation and lowering of surface tension make solder spread excellently.
    The enough heat condition to the workpiece makes solder spread spontaneously. by preheating effect and preventing oxidation.
