BRUNIMIND Empowers European Automotive Electronics Project_ Seamless Integration of SMT Line and THT Assembly Line

Against the backdrop of the rapid transformation of the European automotive electronics industry towards intelligence and electrification, vehicle and component manufacturers have increasingly stringent requirements for the automation, integration, and high reliability of electronic production lines. A well-known European automotive electronics enterprise, aiming to meet the mass production needs of core components such as new energy vehicle electronic control modules and sensors, urgently needed to build an automated production line integrating SMT (Surface Mount Technology) and THT (Through-Hole Technology), to achieve seamless connection, data intercommunication, and full quality control of the two processes. With its profound technical accumulation in the field of electronic manufacturing automation, European localized service capabilities, and rich experience in production line integration, BRUNIMIND became the core partner of the enterprise, tailor-making an integrated SMT+THT production line solution that was successfully commissioned, achieving dual breakthroughs in production capacity and quality.

Project Background and Customer Pain Points

This European automotive electronics enterprise has long been engaged in the R&D and production of automotive electronic control systems and is a core supplier to many well-known vehicle manufacturers. With the rapid expansion of the new energy vehicle market, its order volume has experienced explosive growth. The enterprise's original production model featured independent operation of SMT and THT production lines, with manual connection between the two processes, resulting in several production pain points:

       Low Efficiency Due to Disconnected Processes: The separation of SMT mounting from THT insertion and welding processes, along with time-consuming manual transfer of semi-finished products, led to mismatched overall production line rhythms, making it difficult for the daily output to meet order demands;

       High Errors Caused by Manual Intervention: Manual loading/unloading and station switching between the two processes were prone to PCB damage and component deviation, resulting in persistently high product defect rates. Especially for automotive electronic products, which have strict reliability requirements, the cost of reworking defective products was extremely high;

       Difficult Traceability Due to Data Silos: The SMT and THT production lines were managed independently, with no real-time data intercommunication, making product quality traceability difficult and failing to meet the strict compliance and traceability standards of the European automotive industry;

       Insufficient Production Line Flexibility: The original production line had poor adaptability and could not quickly switch between the production of different specifications of automotive electronic PCBs. Faced with the customer's customized and multi-batch production needs, the adjustment cycle was long and costly.

To address the above pain points, the enterprise proposed the core demand of building an integrated SMT+THT automated production line, requiring seamless process connection, full-process data interconnection, and flexible production adjustment. It also needed to comply with European Industry 4.0 standards and automotive industry quality control requirements. After comprehensively evaluating multiple global automation solution suppliers, the enterprise ultimately chose BRUNIMIND, mainly because BRUNIMIND could not only provide highly adaptable equipment configuration but also achieve in-depth production line integration and localized technical service support.

Core Customer Requirements

Combining the enterprise's production status and development planning, the BRUNIMIND team thoroughly sorted out its core needs and clarified the core goals of production line integration:

1.       Integrated Process Integration: Achieve automated connection of the entire processes of SMT surface mounting, THT through-hole insertion, welding, and inspection, eliminate manual transfer links, and improve the overall operational efficiency of the production line;

2.       Full-Process Data Intercommunication: Build a central production line management and control system to realize real-time collection, analysis, and intercommunication of production data, equipment operation data, and quality inspection data from all SMT and THT processes, supporting full product lifecycle traceability;

3.       Highly Flexible Adaptive Production: The production line must be adaptable to the production of multiple core automotive electronic components (electronic control modules, sensors, on-board power supply boards, etc.), support rapid changeover, and meet multi-batch, small-lot production needs;

4.       Compliance with Strict Industry Standards: The design and operation of the production line must comply with European CE certification and the IATF16949 automotive industry quality system standard, ensuring product quality stability and production compliance;

5.       Localized Rapid Services: Require the supplier to have a European localized service team capable of providing rapid equipment commissioning, fault diagnosis, and after-sales maintenance to minimize production line downtime.

Core Module 3: BRM-MES3.2 Central Production Line Management and Control System (Realizing Full-Process Data Intercommunication)

To solve the problem of data silos in the original production line, BRUNIMIND built an exclusive BRM-MES3.2 central production line management and control system for the customer, which serves as the "brain" of the entire integrated SMT+THT production line and realizes three core functions:

       Real-Time Data Collection: Connect to the equipment systems of each SMT and THT process, and real-time collect production data (output, rhythm, yield), equipment operation data (speed, temperature, fault information), and quality inspection data (defect type, quantity, location) from printing, mounting, welding, inspection and other links;

       Centralized Data Analysis: Conduct real-time analysis of the collected massive data, generate production reports, equipment operation reports, and quality analysis reports, helping customer management grasp the real-time operation status of the production line and timely identify production bottlenecks and quality problems;

       Full Lifecycle Traceability: Bind a unique QR code to each PCB, record its production information, inspection information, and operator information in each SMT and THT process, realizing full lifecycle traceability of products from raw materials to finished products, and meeting the compliance requirements of the European automotive industry;

       Remote Monitoring and Early Warning: Support remote monitoring of the production line operation status via computer and mobile terminal. When equipment fails or production parameters deviate from standards, the system automatically issues an early warning and pushes fault solutions to shorten fault handling time.

Core Design Highlights of Production Line Integration

       Seamless Hardware Connection: Use automated conveyor belts and manipulators to complete the transfer of semi-finished products between SMT and THT processes, realize the rhythm matching of the two processes, ensure the overall smooth operation of the production line, and eliminate manual intervention links;
