Advantage

• More uniform solder paste printing, less consumption, and improved printing performance
• No longer relies on manual addition, saving costs
• More intuitive solder paste usage display, higher efficiency, lower residue, and real-time computer monitoring of solder paste addition frequency and consumption
• Lower solder paste level alarm, avoiding missed or insufficient additions due to manual forgetting to add solder paste
• Fully enclosed system operation, minimizing direct contact with toxic substances in the solder paste and operator health risks
• Pre-extrusion molding of solder paste before dispensing can slightly improve SPI yield
• Eliminates unnecessary downtime, saving time and reducing costs for the production line, increasing output
• Full closed-loop control, real-time monitoring of solder paste usage on the stencil, and automatic sensing to trigger solder addition

Economic benefit analysis

• 1. Saves Labor Time: Assuming manual addition is done once per hour, an 8-hour shift saves 12 minutes, and 24 hours saves 30 minutes, equivalent to 300 RMB. (For a single-track line, the hourly cost is 600 RMB per line). – Assuming one operator per production line and a monthly salary of 5000 RMB, this saves 15 RMB per day in labor costs.
• 2. Saves Solder Paste and Reduces Waste: 32g of solder paste is saved every 24 hours. At 250 RMB per 500g, this saves 16 RMB per day.
• 3. Reduces Board Cleaning and Rework Costs Due to Insufficient Solder: Improving the SPI yield by 1% avoids 1.3 defective products per hour, equivalent to 3.9 RMB per hour (based on 3 RMB per board), saving 93.6 RMB per day.

It is estimated that 60,000 yuan can be saved annually.
