Abstract

Νέα BGA stencil για εξαρτήματα τύπου ball grid array τα οποία παράγονται από μεμβράνες από ελαστομερή υλικά και τα οποία stencil κόβονται διατρυπώνται με τη χρήση ακτινών laser και τα οποία stencil είναι μόνιμα προσαρτημένα μεταξύ των συγκολλημένων σφαιριδίων (3), του εξαρτήματος BGA (2), και του PCB (5). Η θερμοκρασία τήξης του ελαστομερούς υλικού μπορεί να είναι μεγαλύτερη ή μικρότερη από 250 βαθμούς Κελσίου. Τα νέα stencil (1) μπορεί να περιλαμβάνουν μέχρι και 43 τοις εκατό σωματίδια (ή τρίμματα) από ελαστικά αυτοκινήτων τα οποία έφθασαν στο τέλος του κύκλου ζωής των (με 0,2 mm μέγιστο μέγεθος σωματιδίων). Το πάχος του κάθε stencil (1) είναι κατά τουλάχιστον 0,1 mm μικρότερο από τη διάμετρο των σφαιριδίων τα οποία παράγονται από το υλικό συγκόλλησης μετάλλων (3). Τα νέα stencils (1) τοποθετούνται σε επίπεδη επιφάνεια και ένα νέο σύνολο από σφαιρίδια (3) τοποθετείται (με το χέρι) εντός των ανοιγμάτων (4) του stencil.
