Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zur Serienherstellung einer Vielzahl von ankontaktierten elektronischen Bauelementen (7) insbesondere von Modulen und/oder Leistungsmodulen und/oder Leuchtdioden und/oder allgemein elektronisehen Leistungsbauelementen. Es ist Aufgabe ein kostengünstiges und einfaches Verfahren zur Serienherstellung von ankontaktierten elektronischen Bauelementen (7) in großer Stückzahl bereitzustellen. Die vorliegende Erfindung zeichnet sich dadurch aus, dass ein mit Bauelementen (7) bestücktes erstes Band und ein freiliegende Metallleiter (15) aufweisendes zweites Band derart überlagert werden, dass in dem beanspruchten Bandverfahren ein mechanisches und/oder elektrisches Ankontaktieren der jeweiligen Metallleiter (15) an die jeweilige Kontaktfläche (9) des jeweiligen elektronischen Bauelements (7) ausführbar ist. Beide Bänder können in Form von Rollen erzeugt sein. Die elektronischen Bauelemente (7) können nach dem Ankontaktieren vereinzelt oder ebenso als Einzelrolle geschaffen werden. Auf diese Weise ist ein besonders wirksames Herstellungsverfahren bereitstellbar. Das Verfahren eignet sich insbesondere für elektronische Leistungsbauelemente, die zusätzlich auf einfache Weise wärmeableitende Schichten (19) aufweisen können.
Abstract:
The invention relates to a method and a device for interconnecting electronic components in three dimensions. In order to reduce the stray capacities between the connections and the shielding (304) of the device, metallized (42) grooves (40, 41) are cut into the block (3') of stacked circuits, the conductors (21) of said circuit being set back from the corresponding face (302) of the block. Said grooves cut into the connection conductors (21). The assembly is then coated with resin (303) and shielded by metallization (304). The invention is especially suitable for producing more compact three-dimensional electronic systems.

Thin profile battery circuits and constructions, and in particular button-type battery circuits and constructions and methods of forming the same are described. In one implementation, a substrate (16) is provided having an outer surface with a pair of spaced electrical contact pads (20, 22) thereon. At least two thin-profile batteries (24, 26) are conductively bonded (36) together in a stack having a lowermost battery and an uppermost battery. The batteries include respective positive and negative terminals. The lowermost battery has one of its positive or negative terminals adhesively bonded to one of the pair of electrical contact pads while the uppermost battery has one of its positive or negative terminals electrically connected to the other of the pair of electrical contact pads. The batteries can be provided into parallel or series electrical connections.

Abstract:
In a method of manufacturing an electronic component built-in substrate of the present invention, a mounted body including a first insulating layer, a stopper metal layer formed under the first insulating layer of a portion corresponding to a component mounting region and a second insulating layer formed on a lower surface of the first insulating layer and covering the stopper metal layer is prepared, and a concave portion is obtained by penetration-processing a portion of the first insulating layer, which corresponds to the component mounting region to form an opening portion, while using the stopper metal layer as a stopper. Also, the stopper metal layer in the concave portion is removed, then an electronic component is mounted on the concave portion, and then a third insulating layer is formed on the electronic component.
