Abstract
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.
