中文摘要：
本研究藉由模擬半導體構裝元件，探討在改變不同防焊漆厚度時，於不同溫濕保存環境下，經IR-reflow過程之後界面黏著力之變化現象。溫濕保存環境以半導體構裝元件實際上可能遭遇的狀況為選取的依據，經過熱力環境與濕度環境交互影響之後，發現防銲漆厚度的大小，的確會造成黏著強度的變化。
防銲漆厚度的大小會因升高溫度與濕度，導致材料軟化與水氣滲入造成界面黏著強度明顯下降，在本研究之環境歷程與實驗條件下，試片破壞面皆發生在防焊漆與基板(FR-4)之間，故所得強度為防焊漆與FR-4之黏著強度。

Abstract：
This study imitated the IC package with different solder mask thickness in different environment of the temperature and moisture to see if the adhesion strength changed after IR-Reflow process. The temperature and moisture of the environment were decided base on the possible conditions that the IC package might encounter in the real situation. After the temperature and moisture in the environment worked interactively and reciprocally, we found that the thickness of solder mask indeed cause the change of adhesion strength.
The thickness of solder mask affected by the raising of the temperature and moisture caused the apparent reduction of the interface adhesion strength due to the softening of the material and the penetrating of the moisture. Besides, the specimen fracture surface occurred between solder mask and FR-4 substrate under any experimental conditions and progress confirmed that the measured strength is the adhesion strength between solder mask and FR-4.
