To achieve the highest level of ease in
component soldering operations without pre-baking, AIT die-attach pastes have
been engineered with molecular structure of low moisture absorption.
This low moisture absorption is reflected in the consistent bond strength
under extreme moisture exposure.

With the increase usage of lead-free
soldering, high temperature stability is critical. Low weight loss is
engineered into AIT die-attach paste adhesives using stable molecular
structure. The following weight loss measure is a good indicator of the
ability of AIT die-attach pastes in withstanding a higher temperature
soldering operation and long-term high temperature applications.

To
enhance the productivity of the die-attach operations, AIT die-attach pastes
for commercial high volume applications have been designed with 100% solids
without diluent or solvent. The use of fast curing agents enables the adhesive
to cure rapidly. They are ideal for in-line curing manufacturing without
additional post curing.

AIT
designed die-attach pastes for high volume commercial applications
with long pot-life to ensure success in the manufacturing operations.
