Abstract:
A problem addressed by the present invention is that of connecting at least two components (10) together mechanically and/or electrically. According to the invention, this problem is solved in a circuit arrangement with at least two components (10), each having a contact surface (12), by the fact that at least one of the contact surfaces (12) is roughened and the components (10) are connected galvanically and/or mechanically using a press connection of the contact surfaces (12). An advantage of the invention consists of the fact that for creating the connection it is not mandatory for an auxiliary agent (e. g., solder, adhesive, screws, rivets, etc.) to be required. The invention is particularly suited to an automated fixing function and, if applicable, also to a sealing function. Advantageously, soldering processes of known type, e.g., can be replaced or improved. In addition, the invention can be used to advantage in the construction and thermal attachment of heat sinks.

Abstract:
A low power voltage control circuit for use in space missions includes a switching device coupled between an input voltage and an output voltage. The switching device includes a control input coupled to an enable signal, wherein the control input is configured to selectively turn the output voltage on or off based at least in part on the enable signal. A current monitoring circuit is coupled to the output voltage and configured to produce a trip signal, wherein the trip signal is active when a load current flowing through the switching device is determined to exceed a predetermined threshold and is inactive otherwise. The power voltage control circuit is constructed of space qualified components.
Abstract:
Embodiments of the present disclosure are directed to a leadframe package with recesses formed in outer surface of the leads. The recesses are filled with a filler material, such as solder. The filler material in the recesses provides a wetable surface for filler material, such as solder, to adhere to during mounting of the package to another device, such as a printed circuit board (PCB). This enables strong solder joints between the leads of the package and the PCB. It also enables improved visual inspection of the solder joints after the package has been mounted.
