Pressureless Silver Sintering Pastes Die-Attach for SiC Power Devices

SHAREX’s silver sintering pastes are high metal-loading materials designed to fit easily into a dispense process with no change of deposition equipment. The pastes can also use fast “reflow-like” (RFL) sintering processes to form strong joints on many standard leadframe, DBC, and IPM pad finishes, and will bond strongly to die with Ag, Au, or Cu surfaces.
Solder and many standard epoxy-silver materials are proving increasingly unsuitable for many discrete and small module device applications. They may, for example, be incapable of surviving the ambient conditions seen from longer mission profiles for automotive applications. These mission profiles typically drive longer high-temperature operating life (HTOL) and larger temperature swings in usage (thermally cycling).
