    Abstract: Embodiments of the invention include a Printed Wiring Board (PWB) having a first via connected to a top-side signal source, a second via connected to a bottom-side signal destination, and a third via connected to the first via on a lower signal layer of the PWB and further connected to the second via on an upper signal layer of the PWB. In embodiments of the invention, the third via is referred to as an S-Turn via. The S-Turn PWB routing configuration advantageously reduces reflections causes by via stubs at Multi-Giga Hertz (MGH) frequencies. Other embodiments are described.

    Abstract: A layout of a circuit board includes a first signal layer, a second signal layer, and a third signal layer. The first signal layer has a transmission line. The second signal layer is stacked below the first signal layer, and has an opening. The third signal layer is stacked below the first and second signal layers with the second signal layer sandwiched between the first and third signal layers. The third signal layer is electrically connected to the second signal layer, and both of the second and third signal layers are ground layers or power layers. An orthogonal projection of a segment of the transmission line on the third signal layer is overlapped with that of the opening on the third signal layer. Therefore, an equivalent impedance of the segment of the transmission line referring to the second and third signal layers can be increased or decreased.

    Abstract: A multilayered printed wiring board, a multilayer PWB, and a method for manufacturing the same. The multilayer PWB comprises a first main surface and an opposing second main surface, where the multilayer PWB has a height being defined by the distance from the first main surface to the opposing second main surface. The two surfaces and the height together define the thickness of the multilayer PWB. The multilayer PWB comprises a reference ground plane, a microstrip conductor separated from the reference ground plane by a first dielectric layer and a stripline conductor connected with the microstrip conductor and being separated from the reference ground plane by a second dielectric layer. The reference ground plane is formed by two or more different partial reference ground planes positioned at different layers of the multilayer PWB. Furthermore, the reference ground plane is moveable from the first partial reference ground plane to the second partial reference ground plane when a signal current transits from the microstrip conductor to the stripline conductor, and vice versa.
