The position recognition system developed is composed of measuring stations, a reco g nition device, a minicomputer, and cassette t a pe-recorders. The position of the bonding pad is found, generally in real-time, by the recognition device and computer. The computer calculates positional data of all bonding pads and s tores them on a cas s ette tape for a subsequent wire-bonding process. The position recognition me thods discussed are composed of a thresholding al g orithm and a position-finding algorithm. Th e se methods are evaluated from the viewpoint of thresholding stability, recognition rate and positional accuracy.","doi":null,"url":"https://ijcai.org/proceedings/1977/162","pdf":"https://ijcai.org/proceedings/1977/0162.pdf","markdown":"https://ijcai.org/proceedings/1977/162.md","bibtex":"https://ijcai.org/proceedings/1977/bibtex/162","volume":{"slug":"1977","title":"Proceedings of the Fifth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1977","url":"https://ijcai.org/proceedings/1977/","year":1977,"location":"Cambridge, MA, USA","dates":"","editors":"Raj Reddy","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Vision","track":"Vision","number":162,"pages":{"first":685,"last":692},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
