Abstract:
An assembly is provided which includes a first circuit panel having a top surface, a first dielectric element and first conductive traces disposed on the first dielectric element. In addition, a second circuit panel has a bottom surface, a second dielectric element and second conductive traces disposed on the second dielectric element, where at least a portion of the second circuit panel overlies at least a portion of the first circuit panel. The assembly further includes an interconnect circuit panel having a third dielectric element which has a front surface, a rear surface opposite the front surface, a top end extending between the front and rear surfaces, a bottom end extending between the front and rear surfaces, and a plurality of interconnect traces disposed on the dielectric element. The bottom end of the interconnect element abuts the top surface of the first circuit panel and the top end abuts the bottom surface of the second circuit panel, where at least some of the first conductive traces are in conductive communication with the second conductive traces through the interconnect traces.
Abstract:
A decoupling device (10) includes a plurality of capacitors having different capacitances (14, 16, 18) physically mounted in a package (12, 212), and terminals including at least one first terminal (24, 224) and at least one second terminal (26, 226) adapted for mounting the package to a circuit panel. The plural capacitors are connected in parallel between the first and second terminals so as to form plural circuits with different self-resonant frequencies. The device can be mounted as a unit on a circuit board with the first terminals connected to a power conductor and the second terminals connected to a ground conductor, and provides low impedance shunting of noise over a wide frequency spectrum.
