Abstract

The invention belongs to the technical field of chip detection, and particularly relates to mobile phone circuit chip testing equipment, which comprises a fixing plate, wherein a first air cylinder is fixedly connected to the center of the bottom end of a bracket, the output end of the first air cylinder is fixedly connected with an upper detection seat, a lower detection seat is fixedly connected to the position, opposite to the upper detection seat, of the fixing plate, a placement groove is formed in the top end of the lower detection seat, and a first cavity is formed in the lower detection seat. According to the testing method of the mobile phone circuit chip, the chip is placed in a testing placement groove to be detected; when the mobile phone circuit chip is tested through the testing method, the testing position of the mobile phone circuit chip is adjusted through a position adjusting plate, so that the measuring accuracy is guaranteed; and through folding of the upper detection seat and the lower detection seat, the mobile phone circuit chip is ensured to be in a dust-free detection state, so that the problem that when the chip is placed in a detection machine, the contact between the chip and a probe is not tight enough, poor contact easily occurs, and a detection result is wrong is solved.

Description

technical field [0001] The invention belongs to the technical field of chip detection, in particular to a test device and a test method for a mobile phone circuit chip. Background technique [0002] Mobile phone chips usually refer to chips used in mobile phone communication functions, including baseband, processor, coprocessor, RF, touch screen controller chip, Memory, wireless IC and power management IC, etc. Before the chip is packaged at the factory, it is necessary to check whether the performance of the mobile phone chip itself meets the requirements for use. Mobile phone chip testing is an important step. [0003] There are also some technical solutions for chip detection in the prior art. For example, a Chinese patent with application number 202010816916X discloses a chip test socket, including a test socket body, the upper end of which is provided with a support plate, The outer surface of the support plate is provided with a vertical connection port, and one side ...
