Description
Technical Field
The invention relates to an intelligent probe testing module and a testing method thereof.
Background
The traditional probe test PogoBlock module pays attention to structural improvement, the probe test module integrated on line has no detection function, and only after a major fault is stopped, the fault module is disassembled and replaced into a spare part of the probe module, and the fault module adopts an off-line test mode to find a fault source.
In order to cope with the fault condition of the production line, a large number of module spare parts are required to be reserved in the workshop site, so that the stock and the cost are increased, and the flexible space for equipment upgrading is reduced. In case of failure, the failure module is replaced by new hardware to ensure that the production line is still producing normally without stopping, but the specific failure cause of the production line stop can not be determined accurately. When the shutdown fault is not in the module structure, the fault phenomenon cannot be repeated in the offline detection, and the fault can be caused again in the operation process of the production line.
In the offline fault finding process of the conventional probe test Pogoslock module, the problems that field faults cannot be reproduced, the non-production environment is debugged and the like exist.
The fault module needs to be detached, then the fault is confirmed offline, and the root cause is searched for repair. The off-line diagnosis mode can not reproduce the fault phenomenon because the off-line diagnosis mode is separated from the actual application scene. In addition, a great number of verification experiments can be performed to determine whether the module mechanism has a problem. And even if the module repeats the fault phenomenon on the production line, a large number of auxiliary experiments are still needed to determine the specific cause of the fault.
The mechanical action in the probe test PogoBlock module is completely independent from the feedback of the test system, and closed loop feedback is avoided. The structure, control and test of the traditional probe test module are three mutually independent parts. When the structure fails, the control system can only diagnose through own abnormality, and the running states of the structure and the control part greatly influence the test data.
