隨著科技業與電子產業的蓬勃發展,球柵陣列封裝技術(Ball Grid Array;BGA)的應用,已漸漸成為半導體產業中重要的製程技術。而目前針對球高或是共面度的檢測中,經常使用雷射掃描、結構光柵或是電子顯微鏡等高成本的技術來量測,以上所耗費的時間與金錢成本往往造成龐大的負擔,也較無法在實際產線上使用。以目前存在立體視覺技術決定了物體表面深度或高度,然而使用技術的同時,也需要考慮表面紋理特徵來擷取特徵點,進而完成後續量測錫球高度。因此本研究應用多目立體視覺於球柵陣列封裝之精密量測系統,結合工業相機、光學鏡頭、光源設備與XY線性滑軌與影像處理軟體建構一套BGA三維突起量測系統。
With the flourishing electronic industry and optical industry, the ball grid array technology had gradually played important role in Semiconductor Industry. Currently ,Somebody are used to laser-detect, structured light, electron microscope in measurement ,which spend a lot of time and money to cause severe problems that could not on-line. Now ,the stereo vision is used to determine the height and depth of an object, in the same way ,it must consider texture with feature selected ,which complete to measure height of the solder ball. Therefore, the purpose of this study is to develop measurement system ,which combine cameras ,CCD, optical equipment ,XY table ,and software.
