Silver sintering die bonding or pressureless sintering die attach is unique from both solder and epoxies; it neither cures nor does it reflow. Sintered paste instead goes through a process akin to solid diffusion; that is, the metallic particles, generally silver, in the paste diffuse throughout the bonding area to create a strong thermal and electrical connection.
The sintering process in the past utilized high amounts of pressure or force to complete the bond, but pressure-less sintering proved to be the better solution. This process relies on the unique formulation of the sintering material to form a bond that is on par with the thermal and electrical conductivity of solder bonds, without needing to rely on flux or high temperature. There is much less concern about the voiding that comes with soldering processes than that which occurs when the solder liquefies.
