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.
