Applications & Uses
- Applications
- Cure Method
- Application Procedures
- Keep product in aluminum polylaminate protective bag when not in use.
- Before using, remove protective bleached paper liner from film. Place wafer onto adhesive side DDAF.
- Laminate (low heat) wafer onto adhesive until good wetting is achieved. Dice wafer as usual.
- Once dicing is complete, pass wafer under UV light so that die can be released for pick and place operation.
- Cure according to one of the recommended schedules.

Technical Details & Test Data
- Cure Schedules
Temperature Time Pressure 85°C 4 hr 5-15 psi 125°C 90 mins 5-15 psi 150°C 30 mins 5-15 psi 175°C 5 mins 5-15 psi 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.
