　　Measurement and inspection technologies in semiconductor manufacturing are the “eyes” and “rulers” that ensure chip yield, performance, and reliability. The manufacturing of semiconductor wafers is akin to a marathon that spans 400 to 800 precise steps, each requiring meticulous attention and taking up to one to two months. Therefore, at the critical nodes of the … Read more
Nash Bell President of BEST, Inc. Since the late 1990s, Ball Grid Array (BGA) packaging has become the preferred packaging method for electronic devices. Compared to high-density ultra-fine pitch Quad Flat Packs (QFP), BGA packaging can significantly reduce the footprint required on the PCB by approximately 50%. Integrating standard BGA and its stacked counterparts, known … Read more
When a PCB board has completed its layout and routing, and there are no errors reported in connectivity and spacing, does that mean the PCB is finished? The answer is certainly no. Many beginners, as well as some experienced engineers, often rush through the process due to time constraints, impatience, or overconfidence, neglecting the post-design … Read more
To strengthen the safety production defense line, recently, the disciplinary committee members of Honghuayuan Community transformed into “safety supervisors,” participating “embedded” in the safety production inspection and rectification actions, actively involved in formulating inspection plans, and proposing supervision suggestions focusing on key locations and critical links, clarifying the work requirement of “who inspects, who is … Read more
During visual inspection (non-sectioning), voids in the copper layer and coating layer of the hole (void) are common defects. Voids identified during visual inspection refer to areas exposing the substrate material, while voids identified through section analysis refer to areas below the minimum thickness specification, indicating a fundamental difference between the two. Different grades of … Read more
