Problems solved by technology

[0003] The burn-in system in the prior art generally exists in the form of single-board gate output non-connectors. For example, the output interface is generally led out by screwing or welding during use, and the existing burn-in system is used for burn-in. Only the primary side parameters such as current, supply voltage, and fault signal are tested, but the specific functional parameters of the board cannot be tested, so it is impossible to detect device failure and device batch differences under high temperature.

Abstract

The invention provides an intelligent detection system for an IGBT driving single board, relates to the technical field of circuit testing, and is a brand-new aging system architecture comprising a backboard, a control module, a sampling board and an adapter board, the intelligent detection system for the IGBT driving single board controls the sampling board to alternately carry out function testing in the process of aging the IGBT driving single board according to a control instruction, and the batch difference and the high-temperature failure of the IGBT driving single boards are judged according to the functional parameters obtained in the aging process, so that the failure rate of the IGBT driving single boards in later use is reduced.

Description

technical field [0001] The invention relates to the technical field of circuit testing, in particular to an intelligent detection system for an IGBT drive single board. Background technique [0002] After completing a series of processes such as patch welding, the parameters of some components on the circuit will change with time in the initial stage of use, which will affect the stability of specific applications or systems. Therefore, the circuit needs to be aged before use. Specifically, the circuit board is energized and operated for a certain period of time under a specific temperature condition, so that the circuit is stabilized before being used. Aging treatment can effectively screen out defects in circuit design, materials, and processes. [0003] The burn-in system in the prior art generally exists in the form of single-board gate output non-connectors. For example, the output interface is generally led out by screwing or welding during use, and the existing burn-...
