Abstract: In accordance with at least one aspect of this disclosure, a system includes one or more electronics boards and one or more plates configured to interleave the one or more electronics boards in a stack along an axis. When in the stack, an outer surface of the one or more plates is configured to form an outer mold line of a portion of a moving platform. Each of the one or more plates includes an inner diameter and an outer diameter, where the outer surface has an outer circumference at the outer diameter.

Abstract: A stacked circuit card assembly includes a power supply having a positive terminal and a negative terminal, a first circuit card having a first via electrically connected to the positive terminal and a second via electrically connected to the negative terminal, and a second circuit card having a third via aligned with the first via and a fourth via aligned with the second via. The assembly further includes a first conductive stand-off disposed between the first circuit card and the second circuit card and structurally supporting the first circuit card with respect to the second circuit card, and a second conductive stand-off disposed between the first circuit card and the second circuit card and structurally supporting the first circuit card with respect to the second circuit card. The first conductive stand-off provides a conductive pathway between the first via and the third via, and the second conductive stand-off provides a conductive pathway between the second via and the fourth via.

Abstract: A circuit card assembly (CCA) stack includes a first circuit card assembly (CCA) with circuit components mounted thereto, wherein the first CCA includes a power contact and a return contact for powering the first CCA. A plurality of additional CCAs in a stack with the first CCA, wherein each CCA in the plurality of additional CCAs includes respective power and return contacts, and wherein each CCA in the plurality of additional CCAs includes a first aperture and a second aperture for passage of power buses. The first power bus can include one or more power wires bonded to power contacts of the CCAs, and one or more return wires bonded to return contacts of the CCAs.

Abstract: An electronic system includes first and second circuit boards and a flexible circuit connector. The flexible circuit connector is configured to electrically connect the first and second circuit boards. The flexible circuit connector includes first and second connectors and a spiral portion. The first connector is configured to connect to the first circuit board. The second connector is configured to connect to the second circuit board. The spiral portion is connected between the first and second circuit boards and includes a circumferential portion that extends around the second connector.

Abstract: An electronic system of a device includes first and second circuit boards and a flexible connector configured to electrically connect the first and second circuit boards. The flexible connector includes a serpentine portion that includes first, second and third legs. The first leg that extends in a first direction, the second leg extends in a second direction opposite of the first direction, and the third leg extends in the first direction. The first, second and third legs are configured in a common plane when the device is in an operational state.
