Title:
SINTERING DEVICE COMPRISING A COOLING DEVICE IN AN UPPER DIE
Document Type and Number:
WIPO Patent Application WO/2017/137420
Kind Code:
A3
Abstract:
The invention relates to a sintering device (10) for producing a workpiece (30) from at least one component by means of pressure sintering. The sintering device has an upper die (12) and a lower die (14), between which the at least one component is held. The upper die (12) and the lower die (14) can be shifted relative to one another, in order to exert a press force on the workpiece (30) to be sintered. At least one heating device (18a, 18b) for heating the workpiece to be sintered (30) is provided. According to the invention, the sintering device (10) also has at least one cooling device (22a) in the upper die (12), which actively maintains the sintering device (10) at a more constant temperature. The hotter lower die (14) heats the upper die (12) undesirably during the sintering press process and this would lead to the overheating of the upper sintering die (12) without the active, controlled cooling device (22a). In addition, without the cooling device (22a), the maintenance of a constant temperature cannot be guaranteed during short sintering cycle processes. A cooling device (22b) can also be provided in the lower die (14). The workpiece (30) can comprise an electronic assembly having at least one electronic component (36), at least one interconnect device (32) and a joining material (34) that bonds the component (36) and the interconnect device (36), the bond being produced by pressure sintering of the joining material (34).
