Abstract:
1. An apparatus, comprising: an incomplete flip chip package to place into a bottom inner cavity of a lower mold portion, the incomplete flip chip package comprising a chip and a substrate, the chip having a top surface coupled by reflowed solder bumps with an upper surface of the substrate, the chip further comprising a bottom surface opposite the top surface and one or more side surfaces between the top and bottom surfaces; a mold created by mating an upper mold portion with the lower mold portion, the upper mold portion having an upper inner cavity, including an upper inner surface which is coated with a release film, and the bottom surface of the chip butts against the upper inner surface, the lower mold portion having a lower inner surface, and the upper and bottom inner cavities forming a mold inner cavity enclosing the incomplete flip chip package, and forming a runner that has an upper portion that includes the release film coated on the upper inner surface of the upper mold portion, and a lower inner surface that includes the lower inner surface of the lower mold; and a predetermined amount of a liquid resin to inject into the mold inner cavity through the runner, the liquid resin encapsulating substantially all or the one or more side surfaces and substantially all of the upper surface, the liquid resin further filling a gap between the top surface of the chip and an adjacent portion of the upper surface of the substrate, encapsulating the reflowed solder bumps, and curing the liquid resin by maintaining the mold at an elevated temperature for a predetermined period of time, the elevated temperature being equal to or greater than the cure temperature of the filled liquid resin for the predetermined period of time.
