28GHz의 mmWaveThe communication standard of5GThe introduction ofMobile device의 PCB 및 cable Even manufacturing tolerances, which were previously ignored, have become an important factor in design.. In the high frequency rangePCB Number of manufacturing tolerancesoneEven the small difference betweenRFManufacturing tolerances need to be minimized because they affect performance..
However, since reducing manufacturing tolerances means increasing development costs, the manufacturing tolerances suggested by the manufacturerspecand our productsRFWe need to find an appropriate line with performance standards.. In particular, due to the various design variables of FPCBs introduced for the miniaturization and ultra-thin design of mobile devices, it is impossible to sample and physically verify all combinations, and the inspection method for detecting defects during mass production is ambiguous.
In this presentation, we will analyze the impact of manufacturing tolerances of FPCB design variables on RF performance through DoE analysis through custom design and introduce the process of securing the quality of FPCB through this.
