    摘要: An electromagnetic bandgap structure and a printed circuit board are disclosed. In accordance with an embodiment of the present invention, the electromagnetic bandgap structure includes a mushroom type structure comprising a first metal plate and a via of which one end is connected to the first metal plate; a second metal plate connected to the other end of the via; a first metal layer being connected to the second metal layer through a metal line; a first dielectric layer, layer-built between the first metal layer and the first metal plate; a second dielectric layer, layer-built on the first metal plate and the first dielectric layer; and a second metal layer, layer-built on the second dielectric layer. With the present invention, it is possible to solve the aforementioned mixed signal problem by preventing the EM wave of a certain frequency range from being transferred.

    摘要: A high frequency signal transmission line having reduced noise. Particularly, a signal transmission line of the current invention has reduced radiation noise and reflection noise, because a conventional ground guard fence line disposed between signal lines is separated into a plurality of ground line blocks that are spaced apart from each other to shield against noise.

    摘要: Disclosed is a working panel for a multilayer printed circuit board. The working panel for a multilayer printed circuit board is constructed in a manner such that first and second strips, having circuit layers and insulating layers which are layered on the upper and lower sides of a core in the opposite order with respect to each other, are appropriately disposed, by which the working panel can resist warpage due to thermal stress applied during the substrate fabrication process, thus imparting industrially useful effects that promise improvements in the standardization, productivity and yield of products.
