IO. Data Collection: The Eyes of Wisdom in SMT Production
In the Surface Mount Technology (SMT) processo di produzione, data collection plays a pivotal role. It serves as the eyes of wisdom, enabling companies to monitor production status in real-time, ensure product quality, improve production efficiency, and identify potential issues. Data is not only the foundation for production decisions but also the cornerstone for continuous improvement and optimization of production processes.
Ii. Overview of Key Data in SMT Production
The types of key data in SMT production are numerous and include the following:
-
Equipment Status Data: Operating time, downtime, and fault frequency, which reveal the efficiency and stability of the equipment.
-
Production Quantity and Efficiency Data: Product quantities, production speeds, and efficiencies per production cycle, which evaluate the overall performance of the production line.
-
Quality Data: Defect rates and rework rates, which monitor product quality and identify production issues in a timely manner.
-
Material Data: Inventory levels, usage amounts, and wastage rates, which are crucial for material management and cost control.
-
Environmental Data: Temperature, umidità, and other production environment parameters, which affect product quality and equipment stability.
Iii. Specific Strategies and Practices for Data Collection
Determining Data Sources
