| dc.description.abstract | This research aimed to investigate the waterproof handheld mobile device detection, but also to meet the design without flooding the factory production efficiency testing equipment, and test results can be used with the corresponding international standard IPX5 ~ IPX7 and sampling experiments currently marketed products, compared with the findings .
Methodology of research, the first shows the current water testing standards and methods discussed in the existing detection methods, followed by improvement of existing detection methods, design and testing equipment commercially available sampling 30 waterproof mobile phone experiment to verify the test results are the same with the actual immersion .
According to the research results the following conclusions:
In 10Kpa pressure,
Begin to run from the maximum deformation after 15 seconds, the deformation amount of difference is less than 30-50% of qualified IPX7 level phone.
Begin to run from the maximum deformation after 15 seconds, the deformation amount of difference is less than 70% of qualified IPX5 level phone.
As research progresses, laboratory equipment has been designed to be a large number of production lines can be imported copy detection devices. However, many issues yet to be derived from the research, for example, this measurement method has its limitations, some objects can not be measured, and the size of the analyte also has its limitations, as well as test automation, and very worth discussing .
Handheld mobile devices is already a mainstream consumer electronics products, I hope this research can serve as a trigger effect, as a reference to future water testing, and more expect positive displacement bridge diagnosis, there are other aspects of the extension application. | en_US |
