Abstract

The invention discloses a multi-channel automatic testing device and method for a chip, and the device comprises a main control unit, a power module, an electrostatic detection circuit, an antenna open/short circuit detection circuit, and a level detection circuit, and the electrostatic detection circuit, the antenna open/short circuit detection circuit, and the level detection circuit are all electrically connected with the main control unit. The main control unit, the electrostatic detection circuit, the antenna open/short circuit detection circuit and the level detection circuit are all electrically connected with the power module. The method comprises the steps of initializing the main control unit; carrying out electrostatic detection on the chip; carrying out power-on initialization on the detected chip, and carrying out antenna state detection on the detected chip; and carrying out level detection on the detected chip. The chip is prevented from being electrified and damaged, the production detection efficiency is greatly improved through the automatic detection process, and the factory reject ratio is reduced.

Description

technical field [0001] The invention belongs to the technical field of chip testing, and in particular relates to a multi-channel automatic testing device and method for chips. Background technique [0002] With the development of science and technology and the improvement of automation, many chip manufacturing processes have been automated. However, in the process of factory testing, some factory tests for basic performance and functions are usually carried out through manual inspection. Manual inspection is inefficient, and the debugging method is single, which often cannot meet the needs of mass production. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a multi-channel automatic testing device and method for chips. [0004] The specific plan is as follows: [0005] A multi-channel automatic test device for chips, including a main control unit, a power supply module, a static detection circuit, an anten...
