“…In this work, the PF was used to deposit two elements (Sn and Pb). The choice of these elements was not only for its importance in structural, optical and electrical applications [ [12] , [13] , [14] , [15] , [16] , [17] ] but essentially, it was adopted for its low melting points (231.9 °C for Sn and 327.5 °C for Pb) in order to allow understanding the deposition/evaporation processes of the two elements on the top of Si substrates which are heated by ion plasma at different temperatures, according to the anode-substrate distance. It is worth mentioning that the use of high melting point elements in the anode (as Molybdenum) will lead to heating the substrate without deposition of Molybdenum [ 1 ].…”

“…The eutectic Sn-37Pb solder is an important material in the field of electronic packing because of its excellent wettability, electronic conductivity and mechanical properties [1,2]. However, due to the threat of lead to the human body and the environment, lead-free solder has become the development direction in the electronic industry with the restriction of hazardous substances (RoHs) [3,4].…”

The 42 wt.% Sn–58 wt.% Bi (Sn-58Bi) Ball Grid Array (BGA) solder balls were mounted to electroless nickel-electroless palladium-immersion gold (ENEPIG) pads by employing the reflow process profile. The effects of reflow cycles and aging time on the interfacial microstructure and growth behavior of intermetallic compounds, as well as the mechanical properties, were investigated. Pd-Au-Sn intermetallic compound (IMC) was formed at the Sn-58Bi/ENEPIG interface. With the increase in reflow cycles and aging time, the IMC grew gradually. After five reflow cycles, the shear strength of the Sn-58Bi/ENEPIG solder joints first decreased and then increased. After 500 h of aging duration under −40 °C, the shear strength of the Sn-58Bi/ENEPIG solder joints decreased by about 12.3%. The fracture mode transferred from ductile fracture to ductile and brittle mixed fracture owing to the fact that the fracture location transferred from the solder matrix to the IMC interface with the increase in reflow cycles and aging time.

“…Through in-depth interviews, Kathy Durkin (2008) studied the experience of adapting east Asian master's students in the UK to the academic norms of western critical thinking and debate and found that most students integrated their own critical thinking with western critical thinking and debate (Durkin, 2008a). Through experimental studies in education, Charlene Tan investigated the existence and significance of communitarian practices of critical thinking in Asian cultures (Adetunji et al, 2021). Through literature induction, this paper attempts to interpret the relationship between critical thinking and Eastern culture from the perspective of paternalistic leadership.…”

In the context of globalization, critical thinking is still regarded as the core content of higher education. The difference between Eastern and Western cultures has a key impact on understanding critical thinking. When the current literature studies the influence of culture on critical thinking, it mainly considers from the macro level, mainly including ethnic history, traditional customs, religious beliefs, art, ethics, and so on. However, from a specific and micro cultural perspective, how critical thinking is influenced by a culture still lacks effective research. This paper studies the influence of Confucian paternalistic leadership on the development of critical thinking in the East from a specific cultural perspective. The study discovers that Asians are easier to understand how things change and they are more tolerant to conflict, which means that they see things as interrelated and interdependent. They are more likely to use intuitive and experience-based reasoning if there is a conflict between intuitive and logical reasoning. Benevolence and hierarchy in paternalistic leadership promote the formation of cooperative critical thinking in improving the operation of organizations so that the characteristics of oriental critical thinking can be analyzed more comprehensively.
