Method for hybridisation of two components by using different sized solder protrusions and a device that uses two components hybridised according to this method

摘要

The hybridisation method involves: providing a first component 1 with first pads 3 for accommodating protrusions, providing a second component 2 with second pads 5 for accommodating protrusions, the first pads 3 and second pads 5 respectively being intended to line up two by two in order to form pairs of pads, then providing the first pads and/or second pads with protrusions 4 made of a fusible material, then placing the first and second components one on top of the other, then bringing the assembly consisting of the first and second components and consequently the solder protrusions to a soldering temperature in order to interconnect the first and second pads of each pair of pads by soldering the protrusions to these pads, and finally, cooling down the soldered joint thus obtained. ;Some of the protrusions 4 of fusible material fitted on the first and/or second pads 3 and 5 respectively consist of at least three larger-sized protrusions 6, especially taller protrusions, so that before the temperature is increased to the hybridisation temperature, the component only rests on the larger protrusions.
