Reliability technology teaching experiment system

Abstract

The invention provides a reliability technology teaching experiment system. The reliability technology teaching experiment system comprises an upper control microcomputer, a high and low temperature cycling test chamber, a bus type experiment frame, a temperature control instrument, an electrical stress loading / measuring system and a programmable power supply. Discrete electronic components are used as an experimental subject and inserted in a corresponding experiment board, and the experiment board is inserted in the bus type experiment frame inside the high and low temperature cycling test chamber. System control software which is developed in a customized mode is installed in the upper control microcomputer, and can conduct integrated control over stress loading and on-line testing. Temperature changes of the high and low temperature cycling test chamber are changed through the temperature control instrument. Electrical stress borne by the experiment board is controlled through the electrical stress loading / measuring system and the programmable power supply. Measurement data of reliability characteristic quantities of all the experiment components on the experiment board are collected on line and in real time through the electrical stress loading / measuring system. The upper control microcomputer, the high and low temperature cycling test chamber, the bus type experiment frame, the temperature control instrument, the electrical stress loading / measuring system and the programmable power supply are distributed in an integrated cabinet in an integrated mode, and the experiment board is selected for use as needed in an experiment.

Description

technical field [0001] The invention relates to the field of reliability teaching experiment, more specifically, the invention relates to a reliability technology teaching experiment system. Background technique [0002] Reliability test experiments are used to understand and analyze the reliability of products or components; reliability test experiments can also be used to find defects in products or components, and provide a basis for product or component improvement. [0003] The test experiment aimed at the reliability characteristics of conventional low-value and low-voltage discrete electronic components such as diodes, LEDs, and capacitors is a highly practical course that is closely related to actual circuit design and engineering applications; this reliable Sex technology teaching experiments also occupy a very important position in school teaching. [0004] At present, there is no dedicated complete set of equipment for reliability teaching experiments in colleges...
