Abstract

Η επινόηση αναφέρεται σε μέθοδο για την αναγνώριση προτύπων για την συναρμολόγηση πλακετών τυπωμένων κυκλωμάτων με ψηφιακή εκτύπωση και σε σύστημα εφαρμογής της μεθόδου αυτής. Στη μέθοδο, εφαρμόζονται μέθοδοι αναγνώρισης προτύπων για την εξαγωγή πληροφοριών από την απεικόνιση της πλακέτας του τυπωμένου κυκλώματος, με αποτέλεσμα την αυτοματοποίηση της εκτύπωσης του προς στόχευση φυσικού αντικειμένου επί της πλατφόρμας. Η μέθοδος συνίσταται στην ψηφιακή εκτύπωση υλικού που επιστρώνεται ομοιόμορφα σε ένα διαφανές υπόστρωμα δότη και τοποθετείται παράλληλα, σε ένα υπόστρωμα αποδέκτη. Ένας παλμός laser ακτινοβολεί το υπόστρωμα δότη με συνέπεια την αποκόλληση και εκτύπωση μέρους του υλικού στον αποδέκτη. Η συγκεκριμένη μέθοδος επιτρέπει την ελαχιστοποίηση του χρόνου της συνολικής διαδικασίας, με μεγάλη ακρίβεια στη στόχευση και μεγάλη διακριτική ικανότητα στην εκτύπωση.
