Fundamentals of Metal Substrate Structure Principles and Electrical/Thermal Performance

As a PCB engineer who routinely works with high-power, high-density boards, in projects like LED lighting, automotive electronics, and power modules, metal-core substrates are no longer optional materials but a necessity. Many designers new to metal-core substrates tend to treat them as "thickened s

How to Implement Micro-Size PCB Soldering Processes and Defect Prevention and Control

During the full lifecycle of micro-sized PCBs, assembly and soldering constitute a high-risk failure phase second only to design and fabrication. Micro-components and minute solder pads place extremely high demands on soldering process precision, temperature control, and equipment. Even a slight dev

Layout Optimization for Mass Production of PCB Boards in SMT Assembly

SMT (Surface Mount Technology) placement is a core backend process in PCB batch production. The efficiency and yield of an automated SMT line heavily depend on the preliminary PCB layout design. In the batch projects I've encountered, nearly 30% of SMT defects can be traced back to PCB layout issues
