Thermal solutions for system-in-package assemblies in portable electronic devices
First Claim
1. An electronic device, comprising:
- a substrate; and
a system in package assembly comprising;
a plurality of components, the plurality of components including a first component including a first surface mounted to the substrate and a second surface, andone or more thermal plugs including a first thermal plug mounted to the second surface of the first component, wherein a first surface of the first thermal plug directly contacts the second surface of the first component, and a second surface of the first thermal plug directly contacts a shielding layer,the shielding layer dissipating and spreading heat by the first thermal plug to the substrate, wherein the shielding layer is electrically connected to ground.

Abstract
A compact portable electronic device packaged into a System-in-Package assembly and thermal solutions for the device is disclosed. The compact portable electronic device can be assembled into a single package to reduce size and enhance form factor. Several tens or hundreds of components including multiple dies, passive components, mechanical or optical components can be packaged into a single system on a printed circuit board. One or more of the components can dissipate a lot of power resulting in the generation of excess heat. To remove the excess heat, the device can include one or more thermal solutions such as internal thermal plugs, heat spreaders, internal embedded heat sinks, and/or external heat sinks. In some examples, the thermal solutions can dissipate heat via conduction to the bottom of the substrate or via convection to the top of the system or a combination of both.
