Technical Details & Test Data
- Cure Schedules
Temperature Time Pressure 100°C 4 hrs 5-10 psi 125°C 2 hrs 5-10 psi 150°C 1 hr 5-10 psi The die or component can also be tacked on the substrate at 125°C or higher with 5-10 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.
