A method for metalizing at least one blind via formed in at least one substrate, including: a) arranging at least one solid portion of electrically conductive material in the blind via, b) performing a thermal treatment of the solid portion of electrically conductive material, making it melt in the blind via, cooling the electrically conductive material, solidifying it in the blind via, and wherein, before carrying out step a), at least part of the walls of the blind via is covered with a material able to prevent wetting of said part of the walls of the blind via by the melted electrically conductive material obtained during the performance of step b), the solidified electrically conductive material obtained after carrying out step c) being able not to be secured to said non-wetting part of the walls of the blind via.
