Soft solder die attach is a widely used process for the mass production of power and high-reliability automotive devices. Soft solder has excellent heat-dissipation properties of typically 35 W/mK and, owing to its high ductility, exhibits outstanding robustness against delamination....

This paper presents a development of mechanical solder shield, which was integrated to the Soft Solder Dispenser (SSD) die attach machine. The innovation of the mechanical shield has proven its ability to prevent the molten solder overflows to the lead area of the device. As a result, it ...
A die attach process employs a temperature gradient lead free soft solder metal sheet or thin film as the die attach material. The sheet or thin film is formed to a uniform thickness and has a heat vaporizable polymer adhesive layer on one surface, by which the thin film is laminated onto...
