Abstract :
A new fast-cure liquid encapsulant family has been developed. These materials can be cured for less 10 minutes at 150°C and have the characteristics that are equivalent to the purity of the conventional liquid encapsulant for Ics. (Cl-:5 ppm, K+ :1 ppm, Na+:1 ppm). Also, these materials are one-component type and the viscosity increase is approximately 20% after 48 hours at 25°C allowing flexible pot life. The fast-cure liquid encapsulants are suitable for TCP (Tape Carrier Package), COB (Chip On Board) and Flip Chip
