摘要: A bonding system is provided. The bonding system includes (a) a bond head assembly configured for carrying a bonding tool for bonding a semiconductor element to a substrate and (b) a reducing gas conduit for carrying a reducing gas from (i) a reducing gas source to (ii) a bonding area of a bonding system. The reducing gas is configured for use during bonding of the semiconductor element to the substrate at the bonding area. The reducing gas conduit includes a catalyst for producing excess reducing species in the reducing gas prior to the reducing gas reaching the bonding area.

摘要: A method of soldering one or more components to a substrate includes providing a substrate and applying an amount of solder material to the top planar surface of the substrate. One or more electrical components are mounted to the solder material in a predetermined position and orientation. A carrier is provided having one or more magnets embedded therein. The substrate is positioned above the carrier such that each of the one or more magnets is positioned directly below a corresponding electrical component. A carrier cover is positioned above the substrate and the electrical components. The solder material is heated to a predetermined temperature for a predetermined amount of time during which each of the magnets exerts a magnetic force on a corresponding electrical component to maintain its orientation relative to the substrate. The magnets reduce the occurrence of tombstoning of the electrical components during heating of the solder material.

摘要: The invention relates to a method of producing a plate arrangement comprising two plates (1, 2) which, at least in sections, have an intermediate space (4) located between them and a constant distance (d) to one another and/or are arranged parallel to one another and between which a fusible solder material (3, 3′) is arranged. The task of setting a defined distance between the plates as accurately as possible is solved according to the invention by creating a pressure difference between the intermediate space (4) between the plates and the outer space surrounding the plates in such a way that the pressure in the outer space is higher than in the intermediate space (4) and that the temperature of the solder material (3, 3′) is at least temporarily raised above its melting temperature during the existence of the pressure difference.
