Abstract:
1. A method of assembling an multi-component electronic package, comprising: providing a package substrate having defined front and back surfaces, with conductive vias through the package substrate providing electrical connections between the front and back surfaces, and with multiple openings in the package substrate to receive electronic components; securing the front surface of the package substrate on a vacuum support; placing, through the back surface of the package substrate, multiple electronic components having front and back sides within the multiple openings of the package substrate, the electronic components being secured in place by the vacuum support, each electronic component being spaced from an inner periphery of the electronic component's corresponding opening of the package substrate by a gap; aligning the front sides of the multiple electronic components with the front surface of the package; depositing an adhesive filler material within the gap and then curing the adhesive filler material, such that the electronic components within the openings are permanently secured to the package substrate; then adding a liquid dielectric coating to the back side of at least a first electronic component of the multiple electronic components, wherein the first electronic component is thicker than the package substrate; grinding the back side of at least the first electronic component to align the back side with the back surface; and forming circuit features in one or more dielectric layer on both front and back surfaces of the package substrate, circuit features on opposite surfaces of the package substrate being electrically connected to each other by means of the conductive vias through the package substrate, the circuit features including one or more thin-film inductors and conduct interconnects that are electrically connected to the multiple electronic components and the one or more thin-film inductors, the circuit features on at least one surface of the package substrate including a set of contact pads defining external connection locations for the assembled multi-component electronic package.
