CONNECTION USING CONDUCTIVE VIAS

摘要

In one embodiment, a meta-module having circuitry for two or more modules is formed on a substrate, which is preferably a laminated substrate. The circuitry for the different modules is initially formed on the single meta-module. Each module will have one or more component areas in which the circuitry is formed. A metallic structure is formed on or in the substrate for each component area to be shielded. A single body, such as an overmold body, is then formed over all of the modules on the meta-module. At least a conductive vertical interconnect access structure (vias) associated with each component area to be shielded is then exposed through the body by a cutting, drilling, or similar operation. Next, an electromagnetic shield material is applied to the exterior surface of the body of each of the component areas to be shielded and in contact with the exposed conductive vias.

1. An electronic module, comprising:
a substrate comprising a component portion wherein the component portion includes a component area on a surface of the substrate, a first metallic layer that extends along a periphery of the component portion and a first conductive vertical interconnect access structure (via) attached to the first metallic layer at the periphery of the component portion; an electronic component on the component area; an overmold formed over the component area; and an electromagnetic shield formed over the overmold and directly attached to the first conductive via along the periphery of the component portion.
