New energy circuit boards have extremely high requirements for soldering reliability; even a slight deviation in the selection of solder paste and solder wire can cause batch defects such as cold solder joints, bridging, and excessive voiding rates. Combined with real production line failure cases, this article directly addresses core pain points such as insufficient solder paste activity matching, mismatched silver content in solder wire, and lack of coordination between reflow profile and solder paste melting point, and provides immediately executable material verification processes and parameter locking methods.
