LOCTITE ABLESTIK JM 7000 die attach adhesive has been
formulated for use in high throughput die attach applications. This
material has been used successfully on rigid substrates with die sizes
up to 700 mils.
LOCTITE ABLESTIK JM 7000 has been approved by DESC and
Rome Laboratory for military products.
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.
