碩士 === 龍華科技大學 === 電機工程系碩士班 === 106 === Smartphone market has increased a lot recently. People almost cannot live without smartphone and it tends to replace PC in the future. In the first half of 2017, Qualcomm processor ranked first place with the 42% market share of Central Processing Unit (CPU) of smartphone. This paper indicates smartphone’s basic structure, production process and testing process. Based on Qualcomm® Snapdragon™ 821 processors and Radio Frequency software QUALCOMM Radio Control Tool, to set and measure by equipment Agilent 8960 with different frequencies. A standardized analytical method is established for improving production yield and production cost would therefore be decreased.
