摘要:
A hybrid structure of multi-layer substrates comprises a first multi-layer substrate and a second multi-layer substrate. The first multi-layer substrate stacks up first metal layers, first dielectric layers alternately and has VIAs. A border district of a first metal layer connects with a border district of the corresponding first dielectric layer. The border districts are separated from adjacent first metal layers and adjacent first dielectric layers. The second multi-layer substrate stacks up second metal layers and second dielectric layers alternately. A border district of a second metal layer connects with a border district of the corresponding second dielectric layer. The border districts are separated from adjacent second metal layers and adjacent second dielectric layers. The VIAs are located at the border districts of the first dielectric layers and each VIA has electric conductor therein to connect one first metal layer with one second metal layer.

Provided is an illumination device in which wiring is easily performed, and a display device. A connector 331 and light sources 34, 34, ... are mounted on one face of a light source substrate 33. Since a power feeding member 4 is formed by using a flexible printed board, and a light source connecting portion 44 provided in the power feeding member 4 is electrically connected to the connector 331, power is fed from a power supply unit to the light source substrate 33. That is, it is possible to easily perform wiring between the power supply unit and the light source substrate 33 using the flexible printed board. Accordingly, wiring becomes simple, compared to a case of electrically connecting a plurality of feeder lines to the light source substrate 33.

A wide bandwidth circuit board arrangement includes two coplanar substrates separated by a predetermined gap, and at least one bond wire arranged across the gap and interconnecting a respective conducting microstrip line on a first side of each respective substrate. Further, the arrangement includes at least one open stub arrangement configured on the first side of each respective substrate, each open stub arrangement comprising a microstrip extending at an angle from an end of each conducting strip on each respective substrate. Finally, the arrangement includes a ground layer on a second side of each respective substrate, and a defected ground structure arranged on the second side of each respective substrate and laterally overlapping each respective open stub arrangement arranged on the first side.

An anti-lightning-combined-stripline-circuit system is provided. The anti-lightning-combined-stripline-circuit system includes a stripline board including circuitry, and a metal ground bar attached to the stripline board. The metal ground bar has a geometry configured to function as a ground for the circuitry and simultaneously function as a lightning ground for a linear array of elements driven by the circuitry.
