  • Patent number: 9936578
    Abstract: A shielded electronic module is formed on a substrate. The substrate has a component area and one or more electronic components attached to the component area. One set of conductive pads may be attached to the component area and another set of conductive pads may be provided on the electronic component. The conductive pads on the component area are electrically coupled to the conductive pads of the electronic component by a conductive layer. A first insulating layer is provided over the component area and underneath the conductive layer that may insulate the electronic component and the substrate from the conductive layer. A second insulating layer is provided over the first insulating layer that covers at least the conductive layer. In this manner, the conductive layer is isolated from an electromagnetic shield formed over the component area.

  • Patent number: 9807890
    Abstract: The present disclosure is related to electronic modules for electronic components and methods for manufacturing the same. In one embodiment, an electronic module is formed using a first substrate having a first component area and a second substrate having a second component area. One or more electronic components may be attached to both the first component area and the second component area. The second substrate is mounted over the first substrate such that the second component area faces the first component area. An overmold covers the first component area and the second component area so as to cover the electronic components on both the first component area and the second component area. In this manner, the number of electronic components within the electronic module that can be mounted on an area of a printed circuit board (PCB) is increased.

  • Patent number: 7732253
    Abstract: The present invention provides a unique way of connecting a flip-chip die to a substrate. Initially, metallic posts are formed on the flip-chip die and solder bumps are placed on the substrate where the metallic post will ultimately connect to the substrate. The tip layer of flash gold, tin, or other wettable electroplated material is applied to the tips of the metallic posts to prevent oxidation and enhance wettability. The sides of the metallic posts are allowed to oxidize to reduce wettability. To attach the flip-chip die to the substrate, the flip-chip die is initially positioned over the substrate, such that the metallic posts align with and come into contact with the solder bumps. Once the flip-chip die is in place over the substrate, the substrate and the flip-chip are heated to cause the solder bumps to reflow and bond to the tip layers of the metallic posts.
