Abstract

The present invention relates to a three-axis magnetic test socket and magnetic teat system thereof, and particularly relates to a three-axis magnetic test socket capable of providing magnetic fields in three different axes and magnetic teat system thereof. In the three-axis magnetic test socket and magnetic teat system, three sets of coils wound the magnetic test socket are applied instead of solenoid of a traditional tester, which is large and only can provide a magnetic field in single axis, to employed different magnetic fields in three different axes for a DUT. Therefore, one-axis, two-axis, and three-axis magnetic test can be performed to the DUT by the three-axis magnetic test socket and magnetic teat system.

Description

technical field [0001] The present invention relates to a three-axis magnetic test stand and a three-axis test system, in particular to a three-axis magnetic test stand capable of providing three axial magnetic forces for testing and a test system using the three-axis magnetic test stand . Background technique [0002] With the development of MEMS, various small and high-performance sensors with different functions have been developed, such as acceleration sensors, pressure sensors (or pressure gauges), magnetic sensors (or magnetometers), etc. In addition to general electrical testing, these sensors often need to test their sensing performance, such as magnetic sensing, acceleration sensing, etc., so traditional testing machines for electrical testing often need to be loaded with some additional devices In order to test the sensing performance. Since the test of the magnetic sensor requires a test magnetic field, it is often necessary to install a solenoid (solenoid) on t...
