The SMT (Surface Mount Technology) industry has extremely high requirements for nitrogen environment in reflow soldering processes. High-purity nitrogen with a purity of 99.99% is used to form an oxygen-free and low-oxygen protective atmosphere in the soldering area, which can effectively prevent solder oxidation, improve solder wetting performance, reduce soldering defects such as virtual soldering, missing soldering and tin beads, and significantly improve the welding quality of electronic components. The special nitrogen generator for SMT reflow soldering is professionally optimized for the high-precision, continuous and stable nitrogen demand of the electronic manufacturing industry, which is different from ordinary industrial nitrogen equipment.

This professional nitrogen generator adopts the upgraded PSA pressure swing adsorption technology and four-stage purification system, which can stably output 99.99% high-purity nitrogen for a long time. The equipment is equipped with a high-precision pressure stabilization system and gas flow balance device, which can avoid nitrogen purity fluctuation caused by the frequent switching of reflow soldering machine gas consumption. In the SMT production process, slight oxygen content fluctuation will affect the welding effect of precision components. The equipment is equipped with a real-time oxygen content online detector, which can monitor nitrogen purity in real time and automatically alarm and adjust parameters when the purity is lower than the standard to ensure that the oxygen content is strictly controlled below 100ppm.

In terms of structural design, the SMT special nitrogen generator adopts a silent and dust-free design, which meets the dust-free workshop environment standards of electronic factories. The equipment has the characteristics of quick start, stable operation and low energy consumption, and can realize 24-hour uninterrupted continuous gas supply to match the continuous production rhythm of SMT production lines. Compared with the traditional liquid nitrogen supply mode, the self-produced high-purity nitrogen of the equipment can save more than 30% of the production cost for enterprises. At the same time, the intelligent control system realizes automatic operation and unattended management, which reduces manual operation errors and maintenance costs, and is the standard supporting equipment for high-end SMT reflow soldering production lines.
