MULTI-LAYER TRANSMISSION LINE PLATE

摘要

PROBLEM TO BE SOLVED: To provide a multi-layer transmission line plate capable of reducing skew in differential transmission without using a complex process.SOLUTION: The multi-layer transmission line plate includes: a pair of ground layers; a differential wiring disposed between one ground layer of the pair of ground layers and the other ground layer; an insulating layer I, disposed between the differential wiring and the one of the pair of ground layers; and an insulating layer II, disposed between the differential wiring and the other ground layer. The insulating layer I includes a layer containing a resin without containing a glass cloth. The insulating layer I or the insulating layer II includes a layer containing a glass cloth and a resin. The thickness of the insulating layer I is less than or equal to the thickness of the insulating layer II.SELECTED DRAWING: Figure 3
