The SMT solder paste cabinet is a device specifically used for storing solder paste and plays a crucial role in the electronic manufacturing industry.

（1）Structure and Features

   The SMT solder paste cabinet is usually composed of the cabinet body, refrigeration system, control system, storage rack and other parts.

   Cabinet Body:Generally made of stainless steel or cold-rolled steel plate, it has good sealing and heat insulation performance, which can effectively prevent the influence of the external environment on the solder paste.

   Refrigeration System: Through compressor refrigeration, the temperature inside the storage cabinet is controlled within a specific range, usually 0 - 10°C. This temperature range can maintain the activity of the solder paste and extend its service life.

   Control System: Including a temperature controller, humidity controller and alarm system, etc. The temperature controller can precisely control the temperature inside the storage cabinet, and the humidity controller can prevent the solder paste from getting wet. The alarm system can send out an alarm when the temperature or humidity exceeds the set range, reminding the operator to deal with it in a timely manner.

  Storage Rack: Used to place solder paste cans, usually designed with multiple layers, which can make full use of the space of the storage cabinet. The material of the storage rack is generally stainless steel or plastic, which has good corrosion resistance and stability.

（2）Functions and Advantages

       1. Maintaining the Activity of Solder Paste.

       2.The flux in the solder paste will gradually volatilize at room temperature, resulting in a decrease in the activity of the solder paste. The SMT solder paste storage cabinet can slow down the volatilization rate of the flux by controlling the temperature and humidity, maintain the activity of the solder paste, and thus improve the soldering quality.

       3. Extending the Service Life of Solder Paste.

        4. Storing the solder paste correctly can extend its service life and reduce waste. The SMT solder paste storage cabinet can provide a stable storage environment for the solder paste, avoiding the influence of external factors on the solder paste, such as temperature changes, humidity changes, light, etc.

       5.Improving Production Efficiency.

       6. Using the SMT solder paste storage cabinet can ensure that the solder paste is in the best state when in use, reduce the soldering defect rate, and improve production efficiency. At the same time, the automatic control system of the storage cabinet can reduce manual operation and improve the degree of automation of production.

       7. Facilitating Management.

       8. The SMT solder paste storage cabinet can store the solder paste in categories, which is convenient for management and use. At the same time, the control system of the storage cabinet can record the storage time and usage of the solder paste, providing data support for production management.
