Trouble with soldering defects?
- N2We help you clear it by N2 system.
Soldering defect samples | Effect of N2 system reduce soldering defects | |
---|---|---|
A | ·Bridging ·Protrusion icicle ·Insufficient solder filling in PTH ·Soldering defects caused by insufficient heat | Preventing oxidation and preheating effect |
B | ·Damaged components (condenser, LED, etc.) by rapid heat | preheating effect |
*In the soldering industry, ”wetting” is the phenomenon that melted solder contacts with a metal surface and flows and spreads over the surface. “Wettability” means a spontaneous solder spreading.
A : Bridging, Protrusion icicle, Insufficient solder filling in PTH and Soldering defects caused by insufficient heat
Soldering defect causes | Improve soldering environment by N2 system Preventing oxidation and preheating effect. | |
---|---|---|
| Solderbility improves by soldering with nitrogen gas; it can block off oxygen around soldering point and preheat workpiece. See the movie for further details, *The followings are considered causes of soldering defects; how to manipulate soldering iron, the amount and speed to feed solder and oxidation of soldering tip. | |
Further expected effects
If solderbility improves;
|
B : Damaged components (condenser, LED, etc.) by rapid heat
Soldering defect causes | Improve soldering environment by N2 system preheating effect | |
---|---|---|
| Preheating workpiece by heated nitrogen gas alleviates a rapid heat to the heat-sensitive components and allows to set at a low temperature.For further details, click here. |
Further expected effects
If preheating effect is taken;- Soldering process speeds up.
N2 system saves soldering time because preheating makes solder reach melting point rapidly and wet very smoothly.
- Oxidation of soldering tip being reduced.
