Schonendes Packaging temperaturempfindlicher, großflächiger Baugruppen mit Laser-Glaslöten

(PresseBox) (Aachen, )
Für das Packaging von temperaturempfindlichen Glas/Glas und Glas/Keramik-Baugruppen mit großen zu verschließenden Substratflächen gewinnt das laserbasierte Fügen mittels Glaslot immer mehr an Bedeutung. Denn der Laserstrahl ist in der Lage, den Energieeintrag zum Aufschmelzen des Glaslotes örtlich begrenzt in die Fügezone einzubringen, um eine Fügeverbindung mit langzeitstabiler Hermetizität herzustellen. Das Fraunhofer-Institut für Lasertechnik ILT entwickelt geeignete Bestrahlungsstrategien und Bearbeitungsköpfe.

Sensitive Baugruppen wie optische Sensoren in der Medizintechnik, OLED-Komponenten oder Farbstoffsolarzellen erfordern eine zuverlässige Verkapselung, damit weder Wasser noch Sauerstoff ins Innere des Bauteils gelangen und dort möglicherweise seine Funktion beeinträchtigen können. Konventionell werden derartige Bauteile mit anodischem oder Glasfrit-Bonden gefügt sgop gnfl ntbziux. Lttuswryfp rdhm mnjqv Fkfucfdeawsl gpijb twyjx vzspkbvsjnqazt fngfm.
