A process for manufacturing an electronic module including a printed-circuit board, at least one first-type component and one second-type component is disclosed. The process involves placing solder on the board, putting the first-type component in a first position, heating the entire board to melt the solder, resulting in soldering of the first-type component, putting the second-type component in a second position such that the second-type component has leads bearing on the board via the solder, and heating the solder locally to melt the solder such that the second-type component is soldered by applying two electrodes on each lead of the second-type component and making an electrical current flow between the electrodes to heat each lead of the second-type component. Each of the two electrodes directly contacts each lead of the second-type component to make the current flow between the two electrodes via the corresponding lead of the second-type component.
