Method of preparing conductive ribs on a chassis, the chassis with conductive ribs, and method of assembling an electric device including the same

Abstract

The invention discloses a method of preparing conductive ribs on a chassis, the chassis with conductive ribs, and a method of assembling an electric device including the same. The method of preparing conductive ribs on a chassis includes steps as follows. A plastic case is provided with at least one elastic rib integrally formed thereon. Then, a conductive film is formed to overlay on both an inner surface of the plastic case and the surfaces of the elastic rib. The present invention can decrease manpower and costs for preparing and purchasing the conductive foams.

Description

technical field [0001] The invention relates to an electromagnetic interference protection element, in particular to a method for preparing conductive convex ribs on a casing. Background technique [0002] In order to reduce the impact of Electromagnetic Interference (EMI) and Electrostatic Discharge (ESD) on the components inside the computer, traditional methods place a certain amount of conductive foam and conductive cloth (gasket) inside the case. , aluminum foil (Al foil) or copper foil (Cu foil), not only can provide metal shielding effect, but also guide the electromagnetic wave signal of this component to a ground terminal. [0003] For example, when placing the conductive foam inside the casing, the material of the conductive foam needs to be prepared first, because the conductive foam is formed by wrapping a foam body with a conductive adhesive tape. Therefore, when preparing the material of the conductive foam, it is necessary to wrap the conductive adhesive tape...

AI Technical Summary

Problems solved by technology

[0004] However, the steps of wrapping the conductive tape on the outer body of the foam and placing the conductive foam inside the casing will both increase labor costs and manufacturing costs

In addition, conductive foams at different locations on the case have different models, styles, prices, and even different suppliers. In this way, when preparing and purchasing these conductive foams, the industry will consider its inventory and acquisition costs, resulting in waste Considerable manpower and cost

In addition, if the conductive adhesive tape has defects, it will reduce the conductive ability of the conductive foam, thereby weakening the computer's ability to prevent electromagnetic interference and electrostatic discharge
