WebJun 27, 2024 · The area fraction of the AuSn 4 thus slightly decreased after multiple reflow (Table 1). The Au and Pd were oversaturated and subsequently reprecipitated throughout the solder matrix as the refined AuSn 4 particles when the solder was solidified, due to the nearly zero solubility of these elements in the solder below the melting point [22, 23]. WebApr 15, 2024 · The reasons are: Firstly, cast-rolling solder structure is coarser, in which there is a large segregation of components, and the melting points of the phases are inconsistent. When heated to the liquidus temperature, the low-melting eutectic phase first melted, then primary phase of the high melting point and the intermetallic compound …
