We developed a numerical method for simulating the underfill flow of conventional capillary flow and no-flow types in flip-chip packaging. The analytical models for the two types of underfill encapsulation processes are proposed. In the capillary flow type, the underfill material is driven into the
## Abstract Noβflow underfill is used in the assembly of microelectronics to increase the productivity and to decrease the cost of the flipβchip manufacturing. The curing process, especially the gelation of the noβflow underfill, is essential for the yield and reliability of the flipβchip assembly.
