Use of OXYVITAL PSA Nitrogen Generators in PCB Soldering Processes

Use of OXYVITAL PSA Nitrogen Generators in PCB Soldering Processes

In printed circuit board (PCB) manufacturing, nitrogen (N₂) is used as an inert gas to improve soldering quality, prevent oxidation, and enhance the durability of solder joints. OXYVITAL PSA Nitrogen Generators provide high-purity nitrogen for processes such as SMD (Surface Mount Device) soldering, wave soldering, and reflow soldering, reducing defects and increasing production efficiency.

Applications of PSA Nitrogen Generators in PCB Soldering Processes

1. Reflow Soldering (for SMT – Surface Mount Technology)

  • In the soldering of BGA, QFN, and other surface-mounted components, nitrogen prevents oxidation, resulting in stronger and cleaner solder joints.

  • Using nitrogen instead of air during soldering improves solder paste melting and prevents solder bridging.

  • Ensures brighter, cleaner, and defect-free solder points.

2. Wave Soldering

  • In conventional wave soldering with air, oxygen causes oxide layers on solder surfaces, leading to defects during cooling.

  • Nitrogen prevents oxidation on the solder surface, improving soldering quality and reducing solder balling.

  • Provides smoother and more reliable solder joints, enhancing quality in PCB production.

3. Selective Soldering

  • For precise soldering of specific components, nitrogen-controlled soldering processes ensure more stable and reliable joints.

  • Particularly preferred in double-sided PCBs and complex assemblies for consistent soldering quality.

Advantages of OXYVITAL PSA Nitrogen Generators in PCB Soldering

  • Prevents oxidation during soldering, ensuring cleaner and higher-quality solder joints.

  • Reduces soldering defects (bridging, voids, insufficient connections), increasing production efficiency.

  • Prevents oxygen-related reactions in wave soldering and reflow ovens, improving solder paste flow.

  • Minimizes the need for post-solder cleaning, optimizing the production process.

  • Enhances the mechanical strength of solder joints, extending PCB lifespan.

  • Provides a continuous, cost-effective, and reliable nitrogen source without dependency on oxygen cylinders or liquid nitrogen.

OXYVITAL PSA Nitrogen Generators optimize reflow, wave, and selective soldering processes in PCB manufacturing, enabling the production of higher-quality and more reliable electronic components.
