Description

Technical Field

[0001] The present invention relates to the technical field of data monitoring, and in particular to a test data monitoring method for tablet computer motherboard production. Background Art

[0002] In the tablet computer production process, the quality of its motherboard plays a vital role in the performance of the whole machine. In the tablet computer production process, the motherboard undergoes multiple links of testing, including but not limited to functional testing, performance testing, electrical performance testing, etc. In the early tablet computer motherboard production, test data monitoring mainly relied on manual work. Testers used various test tools, such as multimeters, oscilloscopes, etc., to measure and record each parameter of the motherboard one by one. This method is not only inefficient, but also prone to human errors and cannot meet the needs of large-scale production.

[0003] With the development of automation technology, more and more companies have begun to use automated testing equipment and systems to monitor the production data of tablet computer motherboards, which has greatly improved the test efficiency and accuracy. However, automated testing equipment and systems can usually only monitor preset, known failure modes and defect types, and it is often difficult to detect some new, undefined defects or faults. For example, some hidden faults caused by complex electromagnetic compatibility issues or software-hardware interactions may not be detected by conventional automated testing methods. In addition, automated testing equipment is prone to mechanical component failure and wear during long-term, high-intensity operation. Damage to components such as conveyors and fixtures will affect the normal transmission and fixation of the motherboard, resulting in inaccurate test positions, the reliability of image test data, and increased equipment maintenance costs and downtime. At the same time, if the test process is not designed reasonably, some components will receive unnecessary multiple tests or over-testing during the test process, increasing the risk of component damage; if the test equipment is not regularly maintained and calibrated, its test precision and accuracy will decrease, resulting in inaccurate test results, causing some originally qualified originals to be misjudged as unqualified and discarded, resulting in waste, while some defective components cannot be detected and flow into the next process, causing more serious problems and greater losses in the subsequent production process.

[0004] Therefore, there is an urgent need for a test data monitoring method for tablet computer motherboard production to solve the problems of high monitoring costs caused by serious component damage or waste during the existing tablet computer motherboard testing process, and low accuracy and reliability of test data monitoring caused by insufficient monitoring capabilities. Summary of the invention

[0005] The purpose of the present invention is to propose a test data monitoring method for tablet computer motherboard production, which can monitor motherboard test data during the production process, reduce monitoring omissions, and monitor the test data of tablet computer motherboard production in a timely, effective and low-cost manner, thereby improving the accuracy and reliability of test data monitoring.
