Tester for maintainability of electron device

Abstract

The invention discloses an electronic equipment performance testing equipment, special relates to an electronic equipment maintainability testing equipment. Its technical options are an electronic equipment maintenance testing device, including fault setting circuit [2], interface circuits [1], timer [3], and the power supply circuit [5]. The invention will be connected between external cables and electronic equipment being tested or by connecting between the socket within electronic equipment being tested and the circuit board, to facilitate vividly set up outside lines or within line fault, and accurate records fault diagnosis time and repair time through the timer.

Description

technical field [0001] The invention belongs to an instrument for testing the performance of electronic equipment, in particular to an instrument for testing the maintainability of electronic equipment. Background technique [0002] Maintainability is one of the important indicators of the quality of electronic equipment, which is mainly represented by the fault diagnosis time and maintenance time of electronic equipment. In order to make electronic equipment have better maintainability, many electronic equipment is equipped with automatic fault diagnosis function and adopts a structural design that is easy to troubleshoot. At present, the maintainability evaluation mainly depends on the limited fault samples provided by the manufacturer. The fault samples should include external line faults and internal line faults. Due to the lack of special fault setting instruments, manufacturers often cannot provide fault samples for external lines; internal line faults It is mainly se...

AI Technical Summary

Problems solved by technology

At present, the maintainability evaluation mainly depends on the limited fault samples provided by the manufacturer. The fault samples should include external line faults and internal line faults. Due to the lack of special fault setting instruments, manufacturers often cannot provide fault samples for external lines; internal line faults It is mainly set by pulling out the circuit board of the electronic device under test, and manually starting the stopwatch to record the fault diagnosis time and maintenance time

The disadvantages of this maintainability testing method are:

[0003] 1. It is impossible to test the maintainability of external line failures;

[0004] 2. Pulling out the circuit board can only simulate the situation that the whole circuit board is burned out or not plugged in, and cannot simulate the aging or damage of the circuit board components that most often occur in the actual use of electronic equipment;

[0005] 3. Since the pulled out circuit board is known, the recorded fault diagnosis time does not match the actual situation
