Electromagnetic shielding device and method for making the same

Abstract

The present invention is an electromagnetic shielding device which is set on a printer circuit board. The electromagnetic shielding device includes a covering part and a conductive rubber casing. The covering part is composed of one conductive material, and includes a covering board and sidewall connecting to the covering board around. The sidewall extends to the printed circuit board, and has a inside surface, an outside surface relative to the inside surface, and at least one throughout hole. The conductive rubber casing covers the inside and outside surfaces of the sidewall, and fills the throughout hole with part of itself which fixes the casing on the sidewall. The conductive rubber casing also contacts to the printed circuit board, establishing an electrical connect with an earth terminal of the circuit board. The covering part and conductive rubber casing forms an enclosure space to envelop the electrical components integrated on the printed circuit board, and keep them from the disturbance of electromagnetic wave.

Description

technical field [0001] The present invention relates to an electromagnetic shielding device and a manufacturing method thereof, in particular to an electromagnetic shielding device using a conductive rubber (Conductive Rubber) as a frame and a manufacturing method thereof. Background technique [0002] Electromagnetic interference is one of the common problems in electronic equipment. Usually, the circuit will generate electromagnetic waves during application. This electromagnetic wave will affect the transmission signal and working performance of other electronic components. Since the mobile phone requires a faster signal transmission speed, it has a very high requirement for anti-electromagnetic interference. Generally speaking, an electromagnetic shielding device is disposed on a printed circuit board (PCB) of a mobile phone to prevent leakage of electromagnetic waves or interference caused by infiltration of external electromagnetic waves.
