Abstract:
Multichannel RF Feedthroughs. In some examples, a multichannel RF feedthrough includes an internal portion and an external portion. The internal portion includes a top surface on which first and second sets of traces are formed. Each set of traces is configured as an electrical communication channel to carry electrical data signals. The external portion includes a bottom surface on which the first set of traces is formed and a top surface on which the second set of traces is formed. A set of vias connects the first set of traces between the top surface of the internal portion and the bottom surface of the external portion.
Abstract:
A printed circuit board unit includes a printed circuit board (11) including through holes (20) arranged in a grid array on which an integrated circuit (12) is mounted; and a flexible substrate (15) provided on a back side of the printed circuit board, covering the through holes. First lands (36) to which the integrated circuit is connected are formed on a front side of the printed circuit board. Second lands (37) to which the flexible substrate is connected are formed on the back side of the printed circuit board. The first lands and the second lands are connected to first ends and second ends of the through holes, respectively. Third lands (38) are formed on a front side of the flexible substrate so as to face the second lands of the printed circuit board. Fourth lands (39) are formed on a back side of the flexible substrate. The fourth lands are electrically connected to the third lands.
Abstract:
A power electronic module (10) includes heat generating power electronic devices (40-52) mounted on a circuit board (12) within a connector outline (34) circumscribing circuit board through-holes (26) for receiving pin terminals (22) of a connector assembly (18). The power electronic devices (40-52) are thermally and electrically coupled to the circuit board through-holes (26) and connector pin terminals (22) to dissipate heat generated by the power electronic devices (40-52).
