Patent ID: 7510108

Claim:
A method of making an electronic assembly having a laminated circuit board with contact pads on a surface and a flip chip having protruding solder bump on a surface comprising the steps of: placing the flip chip on the surface of the laminated circuit board so that the solder bumps of the flip chip engage the contact pads of the laminated circuit device, providing a heat sink shell having a window, placing the heat sink shell over the flip chip and onto the surface of the laminated circuit board, providing a mold die having a mold cavity, a gate leading into the mold cavity and a vent leading out of the mold cavity, placing the mold die over the heat sink shell and onto the surface of the laminated circuit device outwardly of the flip chip so that the flip chip and the heat sink are in the mold cavity and the mold cavity is sealed, and injecting an epoxy material through the gate into the mold cavity and through the window into space between the flip chip and the laminated circuit board, such that the epoxy material encapsulates the solder bumps and contacts.
