How Nitrogen Generators Can Boost PCB Soldering Quality

If you’ve ever worked in PCB manufacturing, you know that soldering is where quality really shows—or breaks. Tiny mistakes during soldering can lead to weak joints, rework, and delays. One upgrade that’s making a noticeable difference? Nitrogen generators.

Using nitrogen during soldering reduces oxidation on component leads and PCB pads. Less oxidation means solder flows better and creates stronger, more reliable connections. This is especially important for high-density boards with fine-pitch components, where air soldering can cause bridging, tombstoning, or voids.

Nitrogen gas used in PCB production is typically ultra-pure, 99.99% or higher, which ensures consistent results and minimal contamination. A working pressure of around 6 bar is usually sufficient for most soldering and reflow applications, providing a stable environment without the need for complex setups.

Beyond quality improvements, nitrogen also creates a controlled, consistent atmosphere, helping every solder joint meet the same high standard. On-site nitrogen generators supply a continuous, reliable flow of nitrogen without the hassle or cost of cylinders, making production smoother and more efficient.
