Industrial Nitrogen Generator for SMT
Stable Nitrogen for Reliable SMT Quality
1. Background
Surface Mount Technology (SMT) is a widely adopted method for assembling electronic components onto printed circuit boards (PCBs) with high precision and efficiency.
During the soldering stages—such as reflow or wave soldering—nitrogen gas plays a critical role in creating an inert atmosphere. This oxygen-free environment prevents oxidation of solder joints and component leads, ensuring better solder wetting, stronger mechanical bonds, and improved overall product reliability and appearance.
2. Challenge
Make sure your SMT production always has a stable and clean nitrogen supply — with purity up to 99.99% or higher.
Support all your soldering machines at the same time, like reflow ovens, wave soldering, and nitrogen cabinets.
Let you check and manage the system remotely, with simple controls and low maintenance.
Help you cut down gas costs and get your investment back quickly — often in just 1 to 2 years.
3. System Parts and Flow
3.1 Main Equipment
| Air Compressor | Supplies clean compressed air |
| Air Dryer and Filters | Remove moisture and dirt |
| Air Tank | Keeps air pressure steady |
| Nitrogen Generator (PSA or membrane type) | Separates nitrogen from air |
| Buffer Tank | Stores nitrogen to keep flow steady |
| Purity Monitor | Checks nitrogen purity in real time |
| Flow Meter and Valves | Control nitrogen flow |
| Pipes and Distribution System | Deliver nitrogen to machines |
3.2 How It Works
Compressed Air → Dry & Filter → Air Tank → Nitrogen Generator → Buffer Tank → Purity Monitor → SMT Machines
4. Technical Specs
| Parameter | Suggested Value | Notes |
| Nitrogen Purity | ≥ 99.99% (up to 99.999%) | Meets most SMT requirements |
| Production Capacity | Add 20%-30% extra | To handle peak demand |
| Working Pressure | 0.5 to 0.8 MPa | Fits SMT machine needs |
| Control System | PLC control with remote monitoring | Easy to manage and maintain |
| Air Quality | Oil-free and dry | Protects nitrogen generator |
