The invention relates to a thermoelectric generator module with a hot zone (1a) and a cold zone (1b) comprising at least a first metal-ceramic substrate (2), which has a first ceramic layer (6) and at least one structured first metallization (4) applied to the first ceramic layer (6) and is assigned to the hot zone, and at least a second metal-ceramic substrate (4), which has a second ceramic layer (7) and at least one structured second metallization (5) applied to the second ceramic layer and is assigned to the cold zone (1b), and also a number of thermoelectric generator components (N, P) located between the first and second structured metallizations (4, 5) of the metal-ceramic substrates (2, 3). Particularly advantageously, the first metal-ceramic substrate (2), assigned to the hot zone (1a), has at least one layer of steel or high-grade steel (8), wherein the first ceramic layer (6) is arranged between the first structured metallization (4) and the at least one layer of steel or high-grade steel (8). The invention also relates to an associated metal-ceramic substrate and to a method for producing it.
Abstract:
Electronic device heat transfer technology is disclosed. In an example, an electronic device package can include a substrate. The electronic device package can also include a heat transfer component. The electronic device package can further include a heat-generating electronic component coupled to the substrate between the substrate and the heat transfer component. The electronic device package can also include a viscous thermal interface material (TIM) providing a heat transfer pathway between the electronic component and the heat transfer component. In addition, the electronic device package can include a barrier about at least a portion of a periphery of the viscous TIM to maintain the viscous TIM within a confined location in proximity to the electronic component. The TIM is uninterrupted by the barrier within the periphery.
Abstract:
A radio frequency (RF) module having a plurality of channels includes a heat sink having at least one tapered edge; a substrate disposed over a surface of the heat sink such that the tapered edge of the heat sink extends past a boundary of the substrate. RF, logic and power circuitry is disposed on the substrate and one or more RF signal ports are formed on an edge of the substrate to allow the RF module to be used in an array antenna having a brick architecture. The tapered edge heat sink provides both a ground plane for RF signal components and a thermal path for heat generating circuits disposed in the substrate.
Abstract:
Die Erfindung betrifft ein Verfahren zum Herstellen einer elektronischen Baugruppe bzw. zum Demontieren derselben. Außerdem betrifft die Erfindung eine elektronische Baugruppe. Die Baugruppe weist eine Heizeinrichtung (16) auf, die in ein Substrat (11) integriert ist. Diese kann über eine externe Stromversorgung (19) während des Montageprozesses geheizt werden, damit beispielsweise Lötverbindungen (25) eines elektrischen Bauelements (23) aufgeschmolzen werden können. Erfindungsgemäß ist vorgesehen, dass die Heizeinrichtung (16) auch im Betrieb der elektronischen Baugruppe verwendet werden kann, wobei diese dann über das Bauelement (23) direkt angesteuert wird. Hierzu muss anschließend eine elektrische Verbindung zwischen dem Bauelement (23) und der Heizeinrichtung (16) hergestellt werden, die während des thermischen Montagevorgangs noch nicht besteht, um die elektronischen Bauelemente (23) der Schaltung vor einer Beschädigung zu schützen.
