With the development of microelectronic products ( integrated circuit , printed circuit board , etc ) directing to high density , thin separation and low defect ratio , its inspection requirement is higher on aspects of precision , efficiency , universal , and intelligence etc . therefore , this paper researched on the general key techniques in the field of microelectronic products vision inspection , covered the shortage of traditional inspection on aspects of fast and precision locating , image mosaic , and fine defect test , completed theory study on physical dimension and defect inspection of microelectronic products based on machine vision , developed the prototype and used lots of experiments to prove its correctness and feasibility 隨著微電子產(chǎn)品(集成電路芯片、印刷電路板等)向著高密度、細(xì)間距和低缺陷方向發(fā)展,對其檢測技術(shù)在精密、高效、通用和智能化等方面提出了更高要求。由此,本文對微電子產(chǎn)品視覺檢測中的關(guān)鍵技術(shù)進(jìn)行研究,彌補(bǔ)了傳統(tǒng)檢測在精確快速定位、圖像全景組合和精細(xì)缺陷檢測等方面的不足,最終完成基于機(jī)器視覺的微電子產(chǎn)品外形尺寸和缺陷檢測的理論研究和樣機(jī)研制,并進(jìn)行了大量實驗證明其正確性和可行性,力圖為我國自主創(chuàng)新的微電子產(chǎn)品視覺檢測技術(shù)提供理論和實際借鑒。
