摘要： A circuit board shielding assembly includes an electrically conductive fabric over foam gasket that forms part of a circuit board card guide in a computer system. As a user inserts a circuit board assembly into the card guide of the computer system, a carrier tray of the circuit board assembly contacts the electrically conductive fabric of the gasket. The fabric over foam gasket also deforms to follow the geometric contours of the edges of the carrier tray. As such, the fabric over foam gasket forms a substantially continuous electrical contact with the carrier tray and forms part of a Faraday cage to provide EMI shielding to the circuit board. Additionally, the electrically conductive fabric includes certain material properties that cause the fabric to be substantially resistant to flaking electrically conductive fragments when as a user inserts the circuit board assembly within the card guide and generates a shear force relative to the electrically conductive fabric.

摘要翻译：电路板屏蔽组件包括在泡沫垫片上的导电织物，其形成计算机系统中的电路板卡引导件的一部分。当用户将电路板组件插入到计算机系统的卡引导件中时，电路板组件的托盘与密封垫的导电织物接触。泡沫垫圈上的织物也变形以跟随托盘的边缘的几何轮廓。因此，泡沫垫圈上的织物与承载托盘形成基本上连续的电接触，并形成法拉第笼的一部分，以向电路板提供EMI屏蔽。此外，当用户将电路板组件插入卡引导件内并且产生相对于导电织物的剪切力时，导电织物包括某些材料性质，使得织物基本上抵抗剥离导电碎片。
