Magnetic Force‐Induced Self‐Assembly and Flip‐Chip Alignment on Electroplated Multilayer Solder with Tailored Melting Points

Advanced Materials Technologies, EarlyView.
This work demonstrates fluidic self‐assembly and self‐alignment of flip‐chips using a magnetic field for agitation and orientation. Pb‐free solder bumps with tailored transformation imprinted melting points enable selective capturing on low‐melting solder in water. After capturing, final alignment is achieved through magnetic forces.
