APPLYING:
Before use with dispensing equipment, allow encapsulant to be warmed to room temperature (ideally 20-25°C). Thaw encapsulant by placing the syringe in a vertical (upright) position with dispense tip facing downward in an ambient environment. Consult handling instructions** for specific guidelines.
To decrease underfill time, preheat substrate to 100°C prior to encapsulant application.
Mount the syringe onto the dispensing equipment that has been thoroughly cleaned and purge encapsulant through the system until an unbroken flow of encapsulant is extruded. Dispense underfill encapsulant as a corner dot extrusion.
CURING:
Cure encapsulant for 30 minutes at 150°C, or for 15 minutes at 165°C.
CLEANUP:
Remove uncured encapsulant using common organic solvents such as acetone or isopropanol.
SHELF LIFE:
Shelf life is six months from date of manufacture when stored at -40°C in original, unopened container. Syringe must be maintained at -40°C in a vertical (upright) position with the dispense tip facing down. Do not store syringe on its side (horizontally).
