Abstract
Disclosed is a manufacturing method of a weak magnetic field sensor using printed circuit board technology, which obtains positioning information by detecting the earth's magnetic force. The sensor includes: a magnetic layer formed with a pattern of a certain shape; a first stacking plate, which is stacked on the lower surface of the magnetic layer and has a first driving pattern formed thereon; a second stacking plate, which is stacked on the magnetic layer The upper surface of the layer is formed with a second driving pattern; the first and second driving patterns are electrically connected to each other; the third lower stacking board is stacked on the lower surface of the first stacking board and formed with a first a pickup pattern; and a third upper stacking board stacked on an upper surface of the second stacking board and formed with the second pickup pattern, the third lower and upper stacking boards being electrically connected to each other.
Description
field of invention [0001] The invention relates to a weak magnetic field sensor using printed circuit board manufacturing technology and its manufacturing method, in particular to a weak magnetic field sensor using printed circuit board manufacturing technology that is suitable for being installed on a mobile communication terminal for detecting the earth's magnetic force to obtain position information. Magnetic field sensor and manufacturing method thereof. Background technique [0002] With the development of mobile phones and mobile terminals, among the various additional services currently provided, the location information service is gradually established as an important service, and more detailed and convenient services are required in the future. [0003] In order to obtain positioning information, it is necessary to provide a sensor that can accurately find out the current position. A weak magnetic field sensor is used as the device for providing positioning informa...
