Test device and test method for mobile phone PCB board

Abstract

The invention relates to the field of circuit testing, in particular to a testing device for a mobile phone PCB board. The test device includes a frame, a fixture, an industrial robot; a mounting frame, which is arranged at the output end of the industrial robot; a motor, which is mounted on the mounting frame; an eccentric shaft, one end of which is coaxially mounted on the output shaft of the motor; the first The rocker arm, one end of which is installed on the mounting frame through the rotating pair, the middle part of the first rocker arm is provided with a chute, the longitudinal direction of the chute is parallel to the length direction of the first rocker arm, and the other end of the eccentric shaft is inserted in the slide. The groove is inside and slidingly matched with the chute; the probe module is arranged on the free end of the first rocker arm; the controller is used for collecting test data of the probe module. In the present application, the speed of the probe module approaching the PCB board is reduced by the quick return mechanism, and the lower half of the first rocker arm is made of elastic material, so as to realize the slow soft landing of the probe module without reducing the work of the probe module frequency.

Description

technical field [0001] The invention relates to the field of circuit testing, in particular to a testing device for a mobile phone PCB board. The invention also relates to a testing method of a testing device of a mobile phone PCB board. Background technique [0002] At present, there are two main methods for PCB electrical testing: one is the bed of needles in-circuit test (ICT), and the other is the flying probe test. Although the test efficiency of the flying probe test system is slightly inferior to that of the ICT test, the flying probe test system has the advantages of rapidity, economy and flexibility compared with the online test of the needle bed. [0003] Subject to the constraints of the solder joint spacing, for some high-density PCB boards, the coverage rate of the needle bed test can only reach 60% to 70%, while the flying probe test system is based on the network logic relationship of the PCB board. The probe is used for testing, and the probe has a certain ...

AI Technical Summary

Problems solved by technology

[0009] The improvement direction of the above-mentioned patents is to improve the probe of the flying probe device into a split probe connected by an elastic member, or the middle part of the probe is elastic, or the probe is installed on the elastic member, which are all opposite to the probe. The improvement of the needle, so that the unit price of the probe is getting higher and higher

and the probe is a consumable part, which greatly increases the production cost by improving the design of the probe to achieve a soft landing
