01 Main Venue of the 9th Technical Seminar on Enhancing Reliability in Electronic Manufacturing
Research on Soldering Quality Evaluation of Printed Circuit Board Assembly (PCBA)
Zhang Wei, Vice President of Shenzhen Meixin Testing Technology Co., Ltd. In his presentation, Mr. Zhang delved deeply into the quality and failure modes of board-level interconnect solder joints. He analyzed failures such as solder joint cracking, detachment, and degraded electrical performance, laying a theoretical foundation for quality assessment and improvement. Based on failure analysis, he proposed acceptable solder joint criteria and developed rapid, accurate evaluation methods to enhance assessment efficiency. Additionally, he introduced comprehensive testing protocols for raw materials to ensure product quality from the source. These insights inject new vitality into quality control within the electronics manufacturing industry. Sustainable Management Strategies and Practices for Automotive Electronics Supply Chains in a VUCA Environment Cao Zhenghua, Chairman of the IPC CAEC China Automotive Electronics Steering Committee Senior Supplier Quality Specialist, SAIC-GM Co., Ltd. Chairman Cao pointed out that the automotive electronics supply chain faces multiple challenges, requiring flexible and pragmatic management strategies in a VUCA (Volatility, Uncertainty, Complexity, Ambiguity) environment. He proposed advancing Continuous Improvement System 2.0, centered on problem-solving and bottleneck elimination, with the goal of enhancing quality, reducing costs, and improving efficiency. Through methods such as lean management, rapid response, and tiered auditing, factory layouts will be optimized, production line utilization rates enhanced, and waste reduced. Concurrently, a differentiated advancement strategy will be implemented, tailoring approaches to individual suppliers. Chairman Cao's insights offer fresh perspectives for sustainable automotive electronics supply chain management, empowering enterprises to navigate complex environments and achieve high-quality development.
