Abstract:
A method for assembling a circuit card assembly includes populating a plurality of components on a top side of a component layer, performing component-level testing on at least one component of the plurality of components populated on the component layer, adhering a bonding layer to a bottom side of the component layer, the bonding layer to facilitate bonding the component layer to an interconnect layer and to provide connectivity between the plurality of components and the interconnect layer, and forming a single-sided circuit card assembly by adhering the interconnect layer to the bonding layer, the interconnect layer having a top side and a bottom side, the bonding layer adhered to the top side of the interconnect layer.
Abstract:
The present invention relates to a stripline arrangement (10’) comprising a number of stripline layers each comprising a laminate layer (1A, 1B) and conducting layers (2A, 2B, 3A, 3B) provided on each of said laminate layers (1A, 1B), said conducting layers (2A, 2B, 3A, 3B) each comprising a conductive pattern, RF signal (microwave) input and output ports respectively, and an interconnecting arrangement (5) for interconnecting said layers. At least two of said stripline layers are arranged such that a given overlapping zone (L’) is provided between each other facing conducting layers (2A, 2B) of said striplines layers, said interconnecting arrangement (5) comprising a bonding arrangement provided between adjacent and one another facing and overlapping conducting layers (2A, 2B). Connectors (4A, 4B) are provided substantially perpendicularly with respect to an extension plane of the respective stripline layers and crossing said laminate layers (1A, 1B) and conducting layers for, in said overlapping zone, providing contact between the adjacent conducting layers of adjacent stripline layers.
