Technical Details & Test Data
- Cure Schedules
Temperature Time 80°C 8 hrs 100°C 4 hrs 125°C 2 hrs 150°C 1 hr For tack and cure: Tack the die with DAF with heated collet and heated stage holding the header, leadframe, module or substrate at 100-150°C. Post curing at the same temperature
The die or component can also be tacked on the substrate at 100°C or higher with 5 psi. When a filet around the edge of the die or component is observed, the pressure can be released for the rest of the bonding cycle.
