Application Case of Nitrogen Generator for Gree Electric Appliances, Inc.

I. Customer Profile

Gree Electric Appliances, Inc. is a world-renowned leading enterprise in home appliance manufacturing, with professional SMT (Surface Mount Technology) chip mounting and electronic component welding production lines. It has extremely high requirements for production process stability, product qualification rate and workshop production environment cleanliness, and the welding process has strict standards for nitrogen purity and gas supply stability.

II. Application Scenarios

Special nitrogen atmosphere protection for the SMT reflow soldering and wave soldering production lines in the customer's workshop, which is used for anti-oxidation during electronic welding, eliminating cold solder joints and false solder joints, and improving the welding quality and finished product qualification rate of circuit boards.

III. Project Parameters

Application Condition: Nitrogen atmosphere protection for SMT reflow soldering and wave soldering

Nitrogen Purity: 99.9%

Gas Flow Rate: 1000 Nm³/h

Cooperative Purchase: 2 cumulative repurchases

IV. Cooperation Background

During the expansion and production line upgrading of Gree Electric's electronic manufacturing workshop, the original gas supply equipment had unstable purity and high energy consumption, which could not meet the needs of mass SMT welding production. To ensure the welding quality of electronic components and reduce the product defect rate, after comparing equipment from multiple manufacturers, on-site inspections and prototype tests, our company's professional nitrogen generator equipment was finally selected.

V. Usage Effects

The purity of nitrogen produced by the equipment is stably maintained at 99.9%, and the gas supply pressure and flow rate are constant, perfectly matching the continuous production conditions of reflow soldering and wave soldering;

The nitrogen atmosphere effectively isolates oxygen impurities in the air, eliminates welding oxidation and blackened solder joints, and greatly improves the qualification rate of circuit board welding;

The equipment operates fully automatically with one-key start and stop, simple operation and maintenance, adapting to the 24-hour uninterrupted production mode of the factory, with significant energy saving and consumption reduction effects;

The product performance and after-sales service have been highly recognized by the customer. The customer repurchased again during the subsequent production line expansion, establishing a long-term and stable strategic cooperative relationship.

VI. Customer Value

We provide a high-purity, stable and low-cost on-site nitrogen generation solution for Gree Electric's SMT electronic welding production lines, helping the enterprise optimize production processes, reduce production costs and improve core product quality. It is a benchmark cooperation case for nitrogen supporting in the welding process of the home appliance and electronic industry.
