Testing device and method for testing radio equipment shell conductive performance

Abstract

The invention provides a test device for testing the electrical conductivity of the housing of a wireless device and a test method thereof. The test device comprises a network analyzer (8) and a processor (7). The network analyzer (8) is used for outputting a plurality of frequencies to the antenna (11) of the wireless device required for test, so as to allow the antenna (11) of the wireless device required for test to generate a plurality of electrical signals in one-to-one correspondence to the plurality of frequencies; and for outputting the plurality of frequencies and the plurality of electrical signals to the processor (7). The processor (7) receives the plurality of frequencies and the plurality of electrical signals in one-to-one correspondence to the plurality of frequencies, and then judges whether the electrical conductivity of the housing of the wireless device is qualified according to the received plurality of frequencies and the plurality of electrical signals. The test device employs the network analyzer and the radio-frequency test method; directly utilizes the radio-frequency performance characteristics to reflect the electrical conductivity of the housing of the wireless device after the physical vapor deposition (PVD) treatment; overcomes the problems of large error of test resistance and difficulty of selecting the test point; and has good use effect.

Description

technical field [0001] The invention relates to a testing device and method for the electrical conductivity of a wireless device casing. Background technique [0002] After the wireless device casing (including the keyboard) is formed, it needs to be painted and PVD (physical vapor deposition) surface treatment. Due to the PVD surface treatment, the wireless device casing will contain a large amount of metal components, and metal is a conductor, which may damage the antenna of the wireless device under test. Therefore, it is necessary to test the electrical conductivity of the casing of the wireless device after PVD surface treatment to test its influence on the antenna of the wireless device to be tested and ensure that it does not affect the signal reception and transmission of the antenna. [0003] The traditional method of testing electrical conductivity is mainly to test the resistance value with a multimeter. For the PVD surface-treated shell, the thickness of the meta...
