  • Assembly method by silver sintering without pressure
    Patent number: 10828697
    Abstract: An assembly method for assembling a first element to a second element by pressureless metal sintering, the method having a preparation step during which a sintering material is arranged at a bond interface of the elements, a pre-sintering step during which the assembly is heated for a first duration that is longer than five minutes at a first temperature that is higher than 200° C. and strictly lower than or equal to the temperature for activating diffusion at the grain boundaries, and a densification step during which the assembly is heated for a second duration at a second temperature that is higher than or equal to the temperature for activating diffusion at the grain boundaries.
