Ferrite module for electronic equipment and manufacturing method of ferrite module

Abstract

The invention discloses a ferrite module for electronic equipment. The ferrite module comprises a ferrite layer, wherein the ferrite layer covers on the outer side of an antenna or a coil on the inner side wall of a casing of the electronic equipment; the ferrite layer is provided with an inner side surface and an outer side surface; the inner side surface is provide with a first profile surface of which the shape is consistent with that of the outer surface of the antenna or the coil; the outer side surface is provided with a second profile surface of which the shape is consistent with the inside shape of the electronic equipment opposite to the inner side wall of the casing. The invention also provides a manufacturing method of the ferrite module. The ferrite module for the electronic equipment, which is disclosed by the invention, can provide the ferrite layer which can individually cover the antenna or the coil on the inner side wall of the casing of the electronic equipment according to the shape of the inner side wall of the casing of the electronic equipment, so that the gap between the ferrite layer and the antenna or the coil can be reduced and a better electromagnetic shielding effect can be provided in a narrow space. In addition, according to the manufacturing method disclosed by the invention, the individual large-scale production can be conveniently operated.

Description

technical field [0001] The invention relates to a ferrite module used in electronic equipment and a manufacturing method thereof. The ferrite module can be widely used in various electronic equipment, such as mobile phones, computers, MP3, MP4, tablet computers and the like. Background technique [0002] Various wireless functions are widely used in mobile phones, computers, MP3, MP4, tablet computers and other electronic devices, such as Wlan, Bluetooth, GPRS, 3G and other functions are all integrated in the device, the design of antennas for various wireless functions and the placement of positions put, have a considerable impact on the performance of the product. At present, most antennas are designed to be built-in. In the case of a small mechanism space, the placement space is severely squeezed, resulting in insufficient benefits. Short-range contactless communication technologies such as NFC (Near Field Communication, short-range wireless communication) technology or ...

AI Technical Summary

Problems solved by technology

[0007] However, with the trend of personalization of electronic equipment becoming popular, various antennas and coils installed on the casing have different shapes, and the surface is also uneven. It is difficult for the finished ferrite sheet to be closely attached to these surfaces. The shielding effect of electromagnetic waves is not good

In order to overcome this defect, it is often necessary to use a larger ferrite sheet to cover the antenna, but there is no more space on the housing of the electronic device to accommodate these extra parts. Therefore, it is urgent to develop a Individually manufactured ferrite materials for better electromagnetic shielding in tight spaces
