| Summary: | 碩士 === 國立中正大學 === 電機工程研究所 === 89 === This thesis establishes an RF circuit model for the plastic ball grid array (PBGA) package from the approach of time-domain and frequency-domain measurements. The test fixture, specially designed for the PBGA436 package, is developed to ensure the measurement accuracy and reliability. The time-domain measurement is performed with Time Domain Reflection Analyzer (TDR), from which the element values of the circuit model are extracted. To extend the applicable frequency range of the model, the frequency-domain S parameters are measured by Vector Network Analyzer (VNA). With these results, the circuit model established by the time-domain measurement is improved to the 5GHz range.
