Abstract: In this method, a vertical stack is formed on an axis coinciding substantially with the gravity direction and comprising, from top to bottom: the element; the mass in a solid state; and the substrate. The mass is then heated so as to cause it to pass into a liquid state enabling it to spread on the substrate. More particularly, after the stack has been formed, the element is left free to move vertically, and during heating, variation in the vertical position of the element is measured.

Abstract: In this method, the conductive powder mass is placed on the support, and then the member is placed on the mass and a compression force is applied, urging the member against the mass and the support before heating the mass. The magnitude is increased from an initial value to a first predefined value for agglomerating the mass, which value is less than a plastic deformation threshold of the powder mass. Then, the magnitude is maintained at the first predefined value throughout a predetermined duration for agglomerating the powder mass. Finally, the magnitude is increased from the first value to a second predefined value less than a critical threshold for damaging the member but greater than a minimum threshold for sintering the mass at the predetermined temperature, the second predefined value being greater than the first predefined value.
