Abstract: A power electronic assembly includes a board having metal layers laminated onto or between electrically insulating layers, and a laminate inlay embedded in the board. A first metal layer provides electrical contacts at a first side of the board. A second metal layer provides a thermal contact at a second side of the board. A third metal layer is positioned between the first metal layer and the laminate inlay and configured to distribute a load current switched by the laminate inlay. A fourth metal layer is positioned between the second metal layer and the laminate inlay and configured as a primary thermal conduction path for heat generated by the laminate inlay during switching of the load current. A first electrically insulating layer separates the fourth metal layer from the second metal layer so that the fourth metal layer is electrically isolated from but thermally connected to the second metal layer.

Abstract: A semiconductor memory module comprises a control chip that drives various memory chips on a circuit board. The memory chips are connected to the control chip via a control clock bus in a loop fly-by topology. The memory chips are arranged on the module circuit board in such a way that memory chips of different ranks are in connected to the control clock bus alongside one another. A data clock bus for carrying a data clock signal connects a memory chip of different ranks to the control chip in each case in accordance with a point-to-point topology. The semiconductor memory module enables the propagation time of a control clock signal on the control clock bus to be adapted to the propagation time of the data clock signal on the data clock bus.

Abstract: An electronic printed circuit board has a memory module and a contact strip for insertion into another electronic unit. The memory module has at least nine identically designed housing-encapsulated integrated semiconductor memories configured on the printed circuit board. The longer dimension of the housing of one of the semiconductor memories, which is connected as an error correction chip, is oriented perpendicular to the contact strip. The longer dimension of the housings of the other semiconductor memories are oriented parallel to the contact strip. The different orientation of the semiconductor memories makes it possible to reduce the height of the printed circuit board while enabling the rectangular housings to keep the same physical form.

Abstract: A circuit module comprises a circuit board having a plurality of contact elements along a longitudinal edge thereof. The circuit board has arranged thereon a SDRAM memory component, the connections of this SDRAM memory component being each connected via resistance elements, which are implemented as individual resistors, to one of the contact elements through lines of limited length. The individual resistors are arranged in a line which extends parallel to the longitudinal direction of the circuit board.
