Research and Development of Print Quality Inspection System of Biochips

In order to automatically detect the print defects of PET board of a kind of biochip, integrated electro-mechanical method was employed to design the experimental platform for the recognition and marker of PET board, therefore the automatic control of mechanical inspection system was realized; CCD sensor was used to get the image of PET board, and specific computer software was developed to achieve the image processing and recognition of PET board; thus, the automatic inspection system of print quality of biochips was constructed. Practical results indicated that this system can precisely and effectively achieve real-time detection.
