Abstract
The invention relates to a flip-chip assembly process for connecting two microelectronic components () to each other. According to the invention, it is possible either to proportion the spacers () so that they are smaller than the interconnect bumps () or to oversize the latter so that their deformation, after having been plastic during the insertion of connective inserts (), returns to the elastic regime once assembly contact between components () has been reached. Thanks to the invention, it is possible to control with great precision the gap between the two components during their assembly, and this without adding any additional steps to their manufacturing or to the assembly process.
