Abstract:
1. A circuit board structure, comprising: a first multilayered circuit board unit; a second multilayered circuit board unit aligned along respective edge portions with the first multilayered circuit board, each multilayered circuit board unit including a first outer radio frequency (RF) screening layer and a layer including a circuit board; and an interconnect, extending alongside and spaced apart from said edge portions, at least part of which is formed separately from the first and second circuit board units, providing an electrical connection between the first and second circuit board units, the interconnect including a laminate having a first electrically conductive layer and a further layer, the first electrically conductive layer electrically connecting the first outer RF screening layer of each of the first and second multilayered circuit board units; and wherein each of the first multilayered circuit board unit and the second multilayered circuit board unit includes a second outer screening layer such that the layer including a circuit board is disposed between the first outer screening layer and the second outer screening layer, wherein the interconnect is a laminate including a second electrically conductive layer such that the further layer forms an intermediate layer disposed between the first electrically conductive layer and the second electrically conductive layer, and wherein the second electrically conductive layer electrically connects the second outer screening layer of each of the first multilayered circuit board unit and the second multilayered circuit board unit.
