“Glob top” – “Dam & Fill” Harze
In vielen elektronischen Baugruppen erfordern empfindliche Komponenten wie Chips, RF-Komponenten von Quarzoszillatoren, BGAs und CSPs zuverlässigen Schutz gegen aggressive Umgebungen.
Roartis® Epoxid-basierte “Glob Top” – und “Dam & Fill” -Harze mit hohem Tg und niedrigem CTE werden in anspruchsvollen Anwendungen eingesetzt, in denen Kunden eine Beständigkeit gegen thermische Zyklen zwischen -55 ° C und 180 ° C benötigen. Auch umfangreiche Tests zur Feuchtebelastung (2000 Std. 85 ° C / 85% RH) haben sich für Roartis® “glob top” oder “dam & fill” Materialien als kein Hindernis erwiesen.
Wo “dam & fill”-Harze typischerweise für größere Chipanwendungen verwendet werden, werden “glob top” -Harze meistens für kleinere Chips verwendet. Um die Prozesszeit zu minimieren, wurde die Chemie der “dam & fill” -Vergussmassen optimiert, um einen Co-Härtungsprozess zu ermöglichen.
