TYPICAL PROPERTIES OF UNCURED MATERIAL
Viscosity, HAAKE RV-20 Rotoviscometer, mPa·s (cP):
Cone 1º @ Shear rate 22 s
-1 9,000
Work Life @ 25°C, hours 8 to 16
Shelf Life @ -40°C (from date of manufacture), days 365
TYPICAL CURING PERFORMANCE
Cure Schedule
30 minutes @ 150°C
Suggested temperature cures are from 150 to 350ºC. For
applications requiring higher electrical conductivity, a cure cycle of 15
minutes @ 300ºC is recommended. Product properties will not be
reduced by subsequent post die attach thermal exposure, i.e.,
wirebond, and/or lid seal up to 370ºC.
