Abstract:
The invention relates to a starter material for a sintering compound, said starter material comprising particles which at least proportionally contain an organic metal compound and/or a precious metal oxide, the organic metal compound and/or the precious metal oxide being converted during heat treatment of the starter material into the elemental metal and/or precious metal. The invention is characterized in that the particles have a coating containing a reducing agent by means of which the organic metal compound and/or precious metal oxide is reduced to the elemental metal and/or precious metal at a temperature below the sintering temperature of the elemental metal and/or precious metal.

Abstract:
L'invention concerne une structure comprenant un support en céramique. Le support comporte un ou plusieurs caissons conducteurs isolés électriquement les uns des autres. Au moins un élément à semi-conducteurs est lié au support par une substance conductrice (10, 12, 14) qui coopère avec un ou plusieurs caissons du support pour assurer une liaison électrique.
Abstract:
The invention relates to a method for producing a substrate arrangement (10, 10") for connecting to an electronic component (30), comprising the steps of: providing a substrate (11) that has a first side (12) and a second side (13), applying a contacting material layer (15) to the first side (12) of said substrate (11), and applying a pre-fixation agent (18) to at least some sections of a side (16) of the contacting material layer (15) that faces away from said substrate (11). The invention also relates to a corresponding substrate arrangement (10, 10") and to a corresponding method for connecting at least one electronic component (30) to the substrate arrangement (10, 10"). The claimed measures provide for sufficient handling strength during transportation from the place of assembly to the place of connection. The contacting material layer (15) should preferably be applied across the whole surface, or close to the whole surface, on the first side (12) of the substrate (11). The substrate (11), with the applied contacting material layer (15) and the applied pre-fixation agent (18), can be positioned detachably on a carrier (20). When connecting to the electronic component (30, 30'), the substrate arrangement (10, 10") is sintered, crimped, soldered and/or bonded thereto. The substrate (11) can be a metal sheet or a metal strip section, particularly a copper sheet or a copper strip section, a lead frame, a DCB substrate or a PCB substrate. The electronic component (30) can be a semiconductor, a DCB substrate or a PCB substrate.
Abstract:
Es wird ein Bauelement und ein Verfahren zum Herstellen dieses Bauelementes beschrieben, wobei das Bauelement zumindest einen Bauelemente-Chip (1), eine Interconnect-Schicht (2) und ein Trägersubstrat (3) aufweist. Der mindestens eine Bauelemente-Chip (1) ist über eine Interconnect-Schicht (2) mit dem Trägersubstrat (3) verbunden, wobei die Interconnect-Schicht (2) durch verdichtendes druckloses Sintern von auf dem Trägersubstrat (3) aufgebrachtem Sintermaterial gebildet ist. Der Sinterprozess erfolgt durch gleichzeitiges Einwirken von Wärme (11) und Ultraschall (4) auf das Sintermaterial.
Abstract:
A method of and system (200) for manufacturing an electronic device (300, 300'), a curable conductive adhesive for use in the same, and an electronic device (300, 300') are disclosed. The method includes printing a conductive adhesive onto pads at ends of traces on a substrate (310, 360), placing one or more components (320, 340, 340', 350, 355) having a non-standard size and/or shape (e.g. circular, oval or rectangular with rounded corners) onto the pads with the conductive adhesive thereon, and after the component(s) (320, 340, 340', 350, 355) have been placed onto the pads, curing the conductive adhesive at a predetermined temperature or with light having a predetermined wavelength (band). The one or more components (320, 340, 340', 350, 355) having a non-standard size and/or shape may be an antenna (320), a sensor (340, 340') and/or a display (350, 355). The electronic device (300, 300') may further comprise one or more additional components (330, 335, 370) having a standard size and/or shape on a second subset of the pads. The additional components (330, 335, 370) may be an integrated circuit (330, 335) and/or a battery (370). The system (200) comprises a printer (220) configured to print a conductive adhesive onto pads at ends of traces on a substrate, a surface mounting (SMT) machine (230) configured to place one or more components (320, 340, 340', 350, 355) having a non-standard size and/or shape onto the pads with the conductive adhesive thereon, and a curing station configured to cure the conductive adhesive after the component(s) (320, 340, 340', 350, 355) have been placed onto the pads. The SMT machine (230) may include a nozzle head having a surface with a shape identical to or configured to match a shape of the component (320, 340, 340', 350, 355) it picks up.
