Printed circuit boards (PCBs) are essential in electrical assembly. The electrical devices we use every day, from cell phones to computers and televisions, cannot operate without them. The production of these PCBs requires soldering. Which is where nitrogen comes in. It creates an inert atmosphere to avoid oxygen reacting with the solder and forming an oxide layer that can lead to quality problems. Producing your own nitrogen for PCB soldering with Pneumatech’s all-in-one PPNG DX skid offers a host of benefits.

PCBs require precision manufacturing which comes with specific nitrogen requirements:

• Reliability: Without nitrogen, PCB production (often fully automated and 24/7) stops. That means its nitrogen supply must be absolutely reliable.

• Flexible flow: The nitrogen flow in selective soldering is stable. Reflow soldering uses much more nitrogen during start-up. PCB nitrogen systems must be able to meet the needs of all soldering processes, including peak demand.

• The right purity: Selective soldering can require a very high nitrogen purity, whereas wave soldering can work with a lower purity. The ideal PCB soldering nitrogen solution can meet all these standards without unnecessarily overspecifying.

• High nitrogen quality: PCBs are delicate pieces of equipment. Any contamination of nitrogen with dust particles or oil vapors could damage them, which makes high nitrogen quality a key requirement.
  

• Cost savings: The cost of using nitrogen adds up. Keeping nitrogen expenses down is crucial to lowering operating costs.
   

Sustainable production: Sustainability has become a top operational priority that nitrogen solutions must also meet.

Many PCB manufacturing facilities still rely on purchasing nitrogen, but generating it on-site offers clear advantages. It is far more cost-efficient, helping you save money while also reducing your environmental footprint by eliminating the need for bottled or liquid nitrogen deliveries. By producing your own supply, you gain greater control and independence, while also avoiding the hassle and complications of external supply logistics.

The PPNG DX skid’s two-stage generation is the most energy-efficient way to produce high-purity nitrogen. The PPNG HE generator first produces nitrogen at 99.9% purity, then the PPNG DX purification system removes the remaining oxygen using a small amount of hydrogen. This two-stage process requires up to 30% less feed air than a conventional single-stage system.

If you don’t need an all-in-one gas generation system, but just want a nitrogen generator, the Penumatech PPNG HE is your ideal solution. Pneumatech’s premium PSA nitrogen generator gives PCB production facilities top nitrogen purity and quality, reliability, and cost savings.

Pneumatech offers you more than “just” the best nitrogen generation system on the market. We can also provide oxygen generators and all your air and gas treatment equipment.
