Humidity and Temperature sensors
High reliability sensors require molding compounds with good adhesion and reduced moisture uptake in order to increase their MSL performance. Catalytic to this point is the high filler loading that enables a lower moisture uptake.
Application considerations
- Used in variety of applications including mobile devices
- Passing 160°C high temperature operating test
- Passing MSL1 & 1000 TC customer reliability
- Best adhesion on PPF lead frame
- Compatible with cavity and film assisted molding process
