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.
