本論文主要研究的目的是針對不同的靜電槍所釋放的能量而產生不同輻射電場進行比對,首先我們利用示波器與法拉第籠量測出靜電槍的標準電壓波形,並觀察到不同的靜電槍有不同的電壓波形。然後我們使用一壓克力條埋入兩螺桿之靜電放電測試模型,再利用頻譜分析儀記錄靜電槍在兩個螺桿間放電的能量(dBm),之後再使用近場量測置換法來量測出靜電槍在兩個螺桿間放電的輻射場強(V/m)。同時也觀察到兩支不同的靜電槍在相同的頻率卻產生不同的放電場強。為了驗證近場量測置換法是否準確,我們利用一米量測置換法來測試靜電槍在兩個螺桿間放電的功率,再將一米量測置換法的結果與近場量測置換法進行比對。同時也利用FDTD的模擬結果來證明量測置換法的正確性。從實驗結果發現,使用量測置換法所得到的輻射場強是與FDTD的模擬結相同的,表示利用量測測置換法進行功率(dBm)與電場(V/m)的轉換是可行的,而且不同的靜電槍在80 MHz至400 MHz的輻射場強變化是相當大的,在400 MHz之後不同靜電槍的輻射場強才會趨近一致,這也表示靜電耐受測試時,會因不同靜電槍進行測試而產生較大的量測不確定度。

The objective of this thesis is to compare electric fields radiated from different electrostatic discharge (ESD) guns with different levels of energy. At the beginning two screws embedded in an acrylic bar were used as the testing model. The upper screw was contacted directly with an ESD guns and the power across the gap between the upper and the bottom. A result was recorded by a spectrum analyzer. Then electric fields radiated from the gap between two screws were obtained by the near-field substitution measurement method. In the study, different electric fields were also observed from two different ESD guns at the same frequency. In order to check the validity of the near-field substitution measurement method, the power in the gap of the two screws released from ESD guns were recorded by the one-meter substitution measurement method. The power obtained by the one-meter substitution measurement method was compared with that obtained by the near-field substitution measurement method. The validity of the near-field substitution measurement method was also checked by the finite-difference time-domain (FDTD) method. From simulation results and measurement data, it is proven the accuracy of the near-field substitution measurement method is correct. It is also confirmed that the transformation between the power and the electric field is available for the study. From the study, it is also found that there is a large variety in the magnitude of electric fields at frequency of 80 – 400 MHz. The variety in the magnitude of electric fields is negligible at the frequency higher than 400 MHz. It should be noted that there is a huge uncertainty in the ESD immunity testing by different ESD guns.
