Abstract

The invention relates to a test fixture and a test method. The test fixture is used to detect the USB board and includes: a carrier, the carrier is provided with a first positioning structure and a second positioning structure, the first positioning structure is used to fix the main board, and the second positioning structure is used for For fixing the USB board, the FPC board is used to connect the motherboard and the USB board; the power supply is used to connect with the motherboard and can supply power to the motherboard; and the display screen is used to connect with the motherboard to display the test results. It can prevent damage to USB board or motherboard. Even if the FPC board may be damaged, it will not damage the main board and USB board, so the FPC board effectively protects the main board and USB board, ensuring the safety of the test. In addition, the cost of the FPC board is very low, and the test cost will not be increased due to the damage of the FPC board. At the same time, both the main board and the USB board are fixed, which improves the fastening efficiency between the FPC board, the main board and the USB board, thereby improving the test efficiency.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a testing fixture and a testing method. Background technique [0002] For terminal devices such as mobile phones, it is necessary to test the USB (Universal Serial Bus, Universal Serial Bus) small board to detect whether its data identification and charging functions are normal. For the traditional testing scheme, the USB board is usually buckled with the main board, and then the data cable is inserted into the USB board, and the test results are observed through the display interface. However, this solution is likely to cause deviations in the fastening between the USB board and the main board, resulting in damage to the USB board and the main board or even complete scrapping, which will affect the test efficiency and safety. Contents of the invention [0003] A technical problem solved by the invention is how to improve test safety and test efficiency. [0004] A test fixtu...
