Abstract: 1. A method for bonding a metallic wire (13) to a microcircuit conductor (11), characterized in that it includes the steps of : a. applying said wire to the conductor, b. maintaining said wire in close contact with said conductor, c. applying a focussed energy beam (14) directed towards a point at least tangentially in contact with said wire, and forming a hole in said conductor, and d. applying additional energy to portions of said wire adjacent to said point for melting the wire metal so that the metal flows into said hole (15) to form an electrical contact between the wire and the conductor.
