Production test method for communication equipment

Abstract

The disclosed testing method for communication device comprises: setting desired condition in device software; during device aging, when according to the condition, taking test. This invention can make full use of aging time to complete auto testing with high efficiency.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method for production testing of communications equipment. Background technique [0002] With the rapid development of information technology such as the Internet and multimedia, people's demand for large-capacity data communication equipment continues to grow, and the complexity of communication equipment also increases proportionally. Therefore, there are higher requirements for the production test of communication equipment. In the production test of communication equipment, it is necessary to ensure the quality of production test, improve the efficiency of production test, and reduce the cost of production test. [0003] The typical production process of communication equipment veneer is as follows: figure 1 shown. A brief description of each part of the process is as follows: [0004] Single board processing: Complete the welding and assembly of components and circuit boar...

AI Technical Summary

Problems solved by technology

[0012] 1. Existing BIST tests are carried out during the functional test of the communication equipment single board or the whole machine test stage, which takes up the production test time and reduces the production test efficiency

[0013] 2. In the chip-level BIST test, there is a contradiction between test completeness and test efficiency

For example, the complete test of the memory takes a long time. In order to improve the efficiency, the completeness of the test is often chosen to be sacrificed, and only the most basic data lines and address lines are tested for the memory.

[0014] 3. This test is not combined with the aging process of the single board of the communication equipment

[0017] 1. The start and stop of the automatic aging equipment test needs to be controlled by manually inserting or not inserting the slot, which increases the complexity of human operation

[0018] 2. The controllability of the automatic aging equipment test is poor, as long as the single board is not in place, the test will be carried out automatically, and the number of tests cannot be determined

Especially for the shipped boards, if the user does not insert the board tightly (or insert it slowly, or the pins on the backplane are damaged), the burn-in equipment test function will be automatically started, which is not what the user needs. During the test, if the board is unplugged or the power is turned off, there will be risks such as board program loss and board unavailability.

And if the memory is tested too many times, its life will also be reduced
