Abstract:
The connection method between at least two elements (E1, E2) corresponding to a printed circuit (4) and to an electronic component (5), comprises a step of forming a plurality of pad-type stacks (2) of bosses (3), the stacks (2) of bosses (3) being formed on a face (10) of a first (E1) of the elements (E1, E2), the stacks (2) of bosses (3) each comprising the same given number of bosses (3), said method also comprising a step of depositing a brazing product (7) on this first element (E1) provided with stacks (2) of bosses (3), a step of arranging the second (E2) of the elements (E1, E2) on the first element (E1), and a step of remelting the assembly thus formed, in order to obtain an electronic device (1). This method makes it possible to produce a precise and flexible raising of surface mounted electronic components.
