Abstract:
A method for improving the liquid dispensing of IC packages, during a liquid dispensed package process of an IC chip, said IC chip is mounted on a substrate, after forming a resin dam and filling liquid resin on said IC chip and said substrate but before being solidified, a flat plate mold having a shape fitting the shape of liquid resin on said IC chip and which is made of a metal and an air vent is provided at proper position of said flat plate mold, a surface of said flat plate mold is treated by roughening or protruding for pressing over said liquid resin on said IC chip tightly, to be used for flattening said liquid resin on said IC chip after dispensing and for heat dissipation; extra resin and air between said liquid resin and said flat plate mold can be vented away smoothly through said air vent; after said liquid resin is solidified, said flat plate mold remains on said resin for heat dissipation.
