Narrow-gap flip chip underfill composition |
摘要 |
An underfill composition comprises a curable resin, a plurality of filler particles loaded within the resin, the filler particles comprising at least 50 weight % of the underfill composition. The filler particles comprise first filler particles having a particle size of from 0.1 micrometers to 15 micrometers and second filler particles having a particle size of less than 100 nanometers. A viscosity of the underfill composition is less than a viscosity of a corresponding composition not including the second filler particles. |

1. An underfill composition comprising:
a curable resin; a plurality of filler particles loaded within the resin, the filler particles comprising at least 50 weight % of the underfill composition, the filler particles comprising:
first filler particles having a particle size of from 0.1 micrometers to 15 micrometers; andsecond filler particles having a particle size of less than 100 nanometers, wherein a loading of the second filler particles in the underfill composition is below or proximate to a cutoff threshold where the viscosity of the underfill composition begins to increase;wherein a viscosity of the underfill composition is less than a viscosity of a corresponding composition not including the second filler particles. |
