Mobile terminal, SAR test device thereof and SAR test method

Abstract

The embodiment of the invention relates to the field of testing and discloses a mobile terminal, an SAR test device thereof and an SAR test method. In the embodiment, the SAR test device comprises a pedestal and a sensing sheet. The sensing sheet is arranged on the pedestal. The mobile terminal is arranged in a test position of the pedestal. A preset distance is arranged between the sensing sheetand the mobile terminal. The sensing sheet at least covers the SAR antenna region of the mobile terminal in the projection region of the plane where the mobile terminal is arranged. The mobile terminal is used for generating a first test result about whether an SAR index is qualified according to an acquired current SAR value and a first threshold value corresponding to a preset distance when thesensing sheet is sensed. The embodiment of the invention also provides the mobile terminal and the SAR test method thereof. According to the invention, the structure is simple; operation is easy to achieve; cost is quite low; the mobile terminal, the test device and the test method are suitable for factory test environments; mass production test requirements of the factories are met; and test efficiency is improved.

Description

Technical field [0001] The embodiment of the present invention relates to the field of testing, in particular to a mobile terminal and its SAR testing device and SAR testing method. Background technique [0002] Mobile terminals such as mobile phones and tablet computers are commonly used in people’s daily lives, and the terminals are usually close to the human body. In order to keep the influence of electromagnetic waves radiated by the antenna in the terminal on the human body within a safe range, CE certification and FCC certification have an impact on SAR (Electromagnetic wave specific absorption rate) requirements are also more stringent. In order to make the terminal meet the SAR index requirements after leaving the factory, it is necessary to test the SAR index of the terminal before leaving the factory. [0003] The existing SAR testing device for mobile terminals includes a tester, a robotic arm, and a human body model with similar electromagnetic characteristics to the hu...

Problems solved by technology

However, the inventors have found that the prior art has at least the following problems: (1) the existing test device has high requirements for the test environment, and needs to be carried out in a similar laboratory-like test environment, which is not suitable for the factory test environment; (2) Existing test devices have complex structure, high cost, and cumbersome operation, which leads to low test efficiency and cannot meet the mass test requirements of the production line.
