Summary: The impact of four surface finishes on electrochemical migration in printed circuit board production was analyzed through a modified water drop test. The study found that electroless nickel/immersion gold (ENIG) had the best ability to resist electrochemical migration, followed by lead-free hot air solder leveling (HASL), HASL, and Cu. The growth of dendrites in lead-free HASL, HASL, and Cu was related to the solubility product of metal ions, while the electrochemical migration process of ENIG was different, with nickel hydroxide and oxide being the main factors contributing to high electrochemical migration resistance.

Summary: Technological advancements have led to improvements in daily life, but also raised concerns about how to deal with electronic waste, particularly waste PCBs. Recycling waste PCBs, which contain precious materials and components, is challenging due to their diverse composition. A proposed method aims to evaluate the economic feasibility of recycling ICs from WPCBs, involving estimating IC area and weight, and determining the potential metal recovery. The use of deep learning models like YOLO has shown promising results in detecting ICs from WPCBs, with the potential to extract a significant amount of metals and silicon elements for recycling.

Summary: Diesel heavy-duty drayage trucks serving the Ports of Los Angeles and Long Beach are major contributors to air pollution in Southern California. Despite the high cost, it is necessary to replace them with zero-emission trucks to reduce premature deaths and asthma attacks. This study found that in 2012, these trucks contributed to 483 premature deaths and 15,468 asthma attacks. However, with regulations and technological advances, the impacts could be reduced to 106 premature deaths and 2,142 asthma attacks by 2035.
