Estimating the term…
The invention relates to a diffusion soldering device and/or sintering device, to a press tool and to a system comprising these for connecting components of at least one electronic assembly, in particular of a plurality of electronic assemblies, by means of diffusion soldering or pressure sintering. The device comprises an upper tool and a lower tool between which the assemblies are held, wherein the upper tool has at least one pressure pad filled or fillable with a fluid or displaceable medium whose internal pressure is variable and at least one, in particular several, plungers in operative connection to the pressure pad and configured for transmission of a press force, generated by a pressure increase in the pressure pad, to the assemblies. The present invention provides that the upper tool has a guide frame in which the plunger(s) is/are guided axially movable along the effective direction of the press force, and the plunger(s) is/are movably guided inside the guide frame while sealed against the pressure pad. In a subordinate aspect, a press tool is proposed that is usable in an aforementioned diffusion soldering or sintering device, and a multi-module system comprising a press tool and/or an aforementioned device.
A diffusion soldering device and/or sintering device for connecting components of at least one electronic assembly by means of diffusion soldering and/or pressure sintering, with an upper tool and a lower tool between which the at least one assembly is held, wherein the upper tool has at least one pressure pad filled or fillable with a fluid or with a displaceable medium whose internal pressure is variable and at least one plunger in operative connection to the pressure pad and configured for transmission of a press force generated by a pressure increase in the pressure pad to the assembly, wherein the upper tool has a guide frame in which the at least one plunger is guided axially movably along the effective direction of the press force, wherein the at least one plunger is guided movably in the guide frame while sealed against the pressure pad wherein the upper tool has at least one pressure unit with a receptacle for the pressure pad, wherein the pressure unit has a cylinder and a piston movably held therein, wherein the cylinder and the piston define the receptacle for the pressure pad such that the volume of the receptacle is variable by movement of the piston.
