An　automatic　inspection　system　for　biochip＇s　print　quality　is　presented　in　this　paper.　It　consists　of　an　automatic　mechanical　control,　a　CCD　sensor　for　getting　the　image　of　PET　boart,　and　the　special　computer　software　for　image　processing　and　recognition.　Experimental　results　indicate　that　this　system　is　capable　of　providing　a　precise　and　effective　realtime　inspection　for　biochips＇　print　quality.
