| Popis: | 103 Amid technology advances and development increasing number of electronic devices are getting more frequent uses every day. Equipment exposed to their electromagnetic fields and waves may suffer malfunctions caused by undesired impacts which may lead to system failure or accidents and potential threat to major public safety events. This study employs Taguchi method in the parameter design at the initial development stage of panel PC. Control factors of its PCB and mechanic design relevant parameters are determined by electromagnetic compatibility responses of radiated emission, conduction interference, and electrical fast transient/burst immunity (EFT). The noise factors are peripherals used together with the tablet. The optimal design parameter matrix based on results from the application and integration of multivariate analysis method of principal component grey relation and TOPSIS suggests 14 grounding screw holes, cooling aperture of casing at diameter of 3mm and staggered layout, and 300Ω filter located at source of noise. Validation of this matrix shows around 10%, 1% and 8% improvement in radiation, transmission interference, and EFT. The optimal parameter matrix improves electromagnetic compatibility, complies with desired design specification, and qualifies the test specification. |
