The card with microcircuits of this invention includes an electronic module having standardized electrodes. To make up this module a first unit is fabricated including a first insulating substrate covered by the electrodes. Under each electrode is located a first hole. Next there is fabricated a second unit which includes an integrated circuit chip the connection terminals of which are coupled to conductors printed onto a second insulating substrate. One of the free ends of each conductor falls directly over a second hole provided in the second insulating substrate. The arrangement is such that the first hole is coaxial with the second hole corresponding thereto when the units are superposed. The two units are then assembled by superposing them and soldering the free ends of the conductors of the second unit to the electrodes of the first unit by introducing a soldering tool into the second hole. The module is employed in particular in a microcircuit card of standardized dimensions.
