Project Background

Wuhan Lincontrol Automotive Electronic Systems Co., Ltd. is a high-tech, publicly listed enterprise specializing in the R&D and manufacturing of engine management systems (EMS), new-energy vehicle power electronic control systems, and intelligent connected vehicle products. It is the domestic manufacturer with the most comprehensive product lines in independent electronic control systems and is known as the "national engine brain" of China. Wuhan Lincontrol is a market leader in N1-class automotive EMS and is regarded as the top independent electronic control brand in China.

Business Needs

- Low SMT line changeover efficiency; changeovers require extensive manual labor to search for and verify materials.

- Lack of a standardized quality system and systematic process control, creating risks of missed inspections.

- Products cannot be traced to man–machine–material–method–environment (5M1E), resulting in high quality risks and costs.

- Quality data statistics and analysis are not timely, delaying real-time process correction and improvement.

- Production material issuing uses a line-side warehouse deduction model, resulting in delayed and inconsistent inventory records.

- IQC relies on manual inspection request forms, which are prone to loss or omissions, causing uninspected materials to enter the warehouse.

Implementation Overview

N2.MES Manufacturing Execution System, WisBI Intelligent Analytics System

Covers system modeling, factory modeling, label management, warehouse management, process management, production planning, SMT production, DIP production, assembly production, quality management, system integration, equipment integration, and data center functions. The system supports raw material warehouses, finished-goods warehouses, SMT lines, DIP lines, coating lines, and assembly production lines.

How the Solution Addresses Core User Needs

- Full-process barcode management to meet major customer audit requirements and ensure complete quality traceability.

- System-triggered execution of key quality control points.

- Real-time alarms and real-time corrective actions to reduce quality risks and costs.

- Integrated equipment data collection to eliminate isolated databases and enable equipment data sharing.

- Introduction of line-side warehouses; material Kanban low-level warnings combined with PDA-guided replenishment lights to enable rapid material calling from the production line.

- Comprehensive quality system established, with automatic FQC inspection triggered when products exit the line, strictly preventing defective items from entering FQC.

Implementation Benefits

- Material accuracy rate increased to 100%

- Changeover efficiency increased by 30%

- Customer audit pass rate increased to 100%

- Quality traceability accuracy increased to 100%
