Embodiment Construction
[0011] like figure 1 Shown is a system architecture diagram of a preferred embodiment of the electronic component strain ratio analysis system of the present invention. The electronic component strain ratio analysis system 10 runs in a computer 1 , and the computer 1 is connected to a database 2 , an input device 3 and an output device 4 . The database 2 is used to store circuit diagram information, and the circuit diagram information includes information lists of all electronic components on the motherboard to be tested, information lists of connection points of all electronic components, and inspection specification lists of all electronic components. The input device 3 is used for inputting relevant information during the strain ratio test process of electronic components. The computer 1 is used for calculating and analyzing the strain ratio of electronic parts, and generating a strain ratio test report. The output device 4 includes a report display unit 40 and a report p...

The invention relates to an electronic part strain ratio analysis method which comprises the following steps of importing an electronic part information table, an electronic part connecting point information table and an electronic part inspection specification table in a circuit diagram from a database; classifying all parts in the obtained part information table to obtain a part information table of electronic parts in different types; setting a strain ratio calculation parameter of the electronic part in a type to be tested; calculating strain ratios of various electronic parts according to the parameters of the electronic part to be tested, and analyzing the strain ratio and the work temperature of the electronic part according to inspection specifications of each electronic part to obtain an analysis result; and generating a strain ratio test report according to the strain ratio, the work temperature and the analysis result of the electronic part to be tested. In addition, the invention also provides an electronic part strain ratio analysis system.
Description
technical field [0001] The invention relates to a strain ratio analysis system and method for electronic parts. Background technique [0002] Predicting the strain ratio of electronic parts is the basic method to evaluate whether the product is reliable. At present, the strain ratio test of each electronic component arranged on the motherboard is still done manually. However, there are more than a thousand pieces of electronic components in just three types of capacitors, resistors, and inductors on one motherboard. Therefore, if the strain ratio test and analysis of the electronic components on the mainboard are performed manually, not only a lot of working time is wasted, but also the accuracy of the obtained results is greatly reduced due to human errors and rough calculations. Contents of the invention [0003] In view of the above, it is necessary to provide a strain ratio analysis system of electronic parts, which can automatically calculate and analyze the strain ...
