## Background
FIELD
The present disclosure generally relates to the field of electronics. More particularly, an embodiment relates to EMI (Electromagnetic Interference) shielding structure to enable heat spreading and/or low cost assembly.
BACKGROUND
Electronic devices generally rely on signal transmission to operate. Electromagnetic Interference (EMI) can affect signal transmission. For example, in digital circuitry, EMI can modify a signal that is intended to convey a logic 1 to instead convey a logic 0. Hence, such interference can cause the circuitry to generate results that are incorrect. Additionally, electronic circuitry generates heat during operation. Excessive heat may physically damage the electronic circuitry, reduce its lifespan, or even affect the operation of the electronic circuitry.

DETAILED DESCRIPTION
In the following description, numerous specific details are set forth in order to provide a thorough understanding of various embodiments. However, various embodiments may be practiced without the specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to obscure the particular embodiments. Further, various aspects of embodiments may be performed using various means, such as integrated semiconductor circuits (“hardware”), computer-readable instructions organized into one or more programs (“software”), or some combination of hardware and software. For the purposes of this disclosure reference to “logic” shall mean either hardware, software, firmware, or some combination thereof.
As mentioned above, Electronic devices generally rely on signal transmission without interference to operate correctly. Also, excessive heat (e.g., generated during operation) may physically damage the electronic circuitry, reduce its lifespan, or even affect the operation of the electronic circuitry. To this end, some electronic devices may utilize an EMI shielding and/or a heat spreader to address the EMI and/or thermal management issues. In some designs, this may be achieved by placing a metal perimeter frame around the electronic components and also capping the components with a heat spreader. However, this construction requires multiple parts and assembly steps, and fails to accommodate lower cost and faster assembly goals.
Some embodiments provide an EMI (Electromagnetic Interference) shielding structure which also providing heat spreading functionality and/or low cost (as well as faster) assembly. Moreover, EMI shield for small form factor devices (which fails to provide a heat spreader function as will be further discussed with reference to FIGS. 1-2) are usually constructed of stamped sheet metal. Instead, in some embodiments, sheet metal can be stamped such that at least one of its surfaces (e.g., top and/or side surface(s)) has a dome feature that is then flipped or depressed after surface mounting of the EMI shield to make (e.g., direct physical and/or) thermal contact with the logic components. The thermal/physical contact between the dome feature and the logic component(s) would then act as a heat spreader. This way, the shield can be soldered to the motherboard together with other logic devices, e.g., without affecting the surface mount process, reducing assembly steps, reducing the number of assembly parts, and/or saving time. The dome feature may be depressed (e.g., by a user, by automated manufacturing equipment, as part of packaging, etc.).
Furthermore, some embodiments may be applied in computing systems that include one or more processors (e.g., with one or more processor cores), such as those discussed with reference to FIGS. 8-11, including for example small form factor or mobile computing devices, e.g., a smartphone, tablet, UMPC (Ultra-Mobile Personal Computer), laptop computer, UltrabookTM computing device, wearable devices (such as a smart watch, smart glasses, etc.), 2 in 1 systems, etc. However, embodiments discussed herein are not limited to mobile computing devices and may be applied in any type of computing device, such as a work station, a server, a super computer, etc. Also, some embodiments are applied in computing devices that include a cooling fan as well as fanless computing devices.
Moreover, some existing solutions for provision of EMI shielding and thermal spreading are shown in FIGS. 1 and 2. More particularly, FIG. 1 illustrates a perspective view of a circuit board 101 which may include various electronic components (shown as smaller gray and black cubes) and an EMI shield with a top portion 102 and a surrounding portion 104. FIG. 2 illustrates an exploded view of the EMI shield of FIG. 1.
As shown in FIG. 2, the top portion of the shield 102 is removable from the surrounding portion 104. A gap pad 202 may be provided between the top portion of the shield 102 and a logic component 204. The gap pad 202 facilitates a thermal contact between the shield and the logic component to help with heat dissipation. In this type of structure, a metal perimeter cage 104 is soldered to the board 101 along with other devices and the gap pad 202 may be attached later in the assembly process. Hence, to provide this shield and heat spreader, a number of assembly steps have to be performed to assemble the various parts. The process can be more time-consuming, more complex, and less cost-effective than some embodiments discussed herein.
FIGS. 3, 4, 5, 6, and 7 illustrate various views of EMI shielding structure to enable heat spreading and/or low cost assembly, according to some embodiments. More specifically, FIGS. 3-5 illustrate perspective views of the EMI shield 302 according to some embodiments. FIG. 4 illustrates an exploded view. FIGS. 6 and 7 illustrate cross-sectional side views of the EMI shielding structure 302 according to some embodiments.
Referring to FIGS. 3-7, some embodiments propose a new structure (e.g., constructed of stamped sheet metal, e.g., constructed with stainless steel, etc.) for an EMI shield 302, in which a dome feature 304 is provided on the top surface of the EMI shield 302. The dome feature 304 may be provided as part of a stamped sheet metal, e.g., during the same stamping process that provides the EMI shield 302, or alternatively be formed during a different stamping process (i.e., before or after the stamping process that provides the shield 302). Further, the vertical darker lines in the side view FIGS. 6 and 7 correspond to background components.
Before surface mount, this dome protrudes outward (e.g., as shown in FIGS. 3, 4, and 6), so that the dome 304 does not make physical (and/or thermal) contact with any components below the shield (such as logic component 204, as illustrated in FIG. 4, 6, or 7). The spacing provided by the protrusion (which may provide a gap of (or no more than) about 2 mm between the surface of the protruded dome and the logic component 204) is intended to not affect the soldering process or cause damage to any logic component, e.g., due to excessive force, pressure, or heating applied during the surface mount process.
As discussed herein, “surface mount” generally refers to a process in which various components (such as the shield 302 and/or logic components (e.g., 204)) are mounted onto a circuit board (or printed circuit board). The mounting may be achieved by glue and/or a soldering process. The soldering process generally includes the provision of a fusible metal alloy (also referred to as a solder), with or without flux, to join metal work pieces (such as pins and/or wires). The solder material will have a lower melting point than the work pieces. After work pieces (such as the circuit board, logic components, and/or the shield 302) are assembled and solder applied, heat is applied to reflow the solder and join the metal work pieces. In an embodiment, the EMI shield 302 may not be soldered to the circuit board as long as some distance (e.g., about 2 mm in some implementations) is maintained between the shield and logic component (except as discussed herein with reference to the dome feature 304).
Furthermore, after surface mount, the dome feature 304 can be pushed down or depressed (as shown in FIGS. 5 and 7) to make direct physical or thermal contact with the logic devices underneath (such as logic component 204). The dome feature may be depressed (e.g., by a user, by automated manufacturing equipment, as part of packaging, etc.). Additionally, the EMI shield 302 may be made of very thin sheet metal (e.g., about 0.3 mm to 0.5 mm thick in some embodiments), and this dome feature can be easily flipped.
In some embodiments, the dome feature 304 can make contact with other heat spreaders (e.g., other domes and/or a heat spreader material such as 202 of FIG. 2). Also, while FIGS. 3-7 illustrate a circular shape for the dome feature 304, other shapes may be utilized such as a square shape, an elliptical shape, a rectangular shape, a polygonal shape, combinations thereof, etc.
In some embodiments, various components in a computing system (such as those discussed with reference to FIGS. 8-11) may be protected by the EMI shield discussed herein. Also, one or more of the components discussed herein can be embodied as a System On Chip (SOC) device. FIG. 8 illustrates a block diagram of an SOC package in accordance with an embodiment. As illustrated in FIG. 8, SOC 802 includes one or more Central Processing Unit (CPU) cores 820, one or more Graphics Processor Unit (GPU) cores 830, an Input/Output (I/O) interface 840, and a memory controller 842. Various components of the SOC package 802 may be coupled to an interconnect or bus such as discussed herein with reference to the other figures. Also, the SOC package 802 may include more or less components, such as those discussed herein with reference to the other figures. Further, each component of the SOC package 820 may include one or more other components, e.g., as discussed with reference to the other figures herein. In one embodiment, SOC package 802 (and its components) is provided on one or more Integrated Circuit (IC) die, e.g., which are packaged into a single semiconductor device.
As illustrated in FIG. 8, SOC package 802 is coupled to a memory 860 via the memory controller 842. In an embodiment, the memory 860 (or a portion of it) can be integrated on the SOC package 802.
The I/O interface 840 may be coupled to one or more I/O devices 870, e.g., via an interconnect and/or bus such as discussed herein with reference to other figures. I/O device(s) 870 may include one or more of a keyboard, a mouse, a touchpad, a display, an image/video capture device (such as a camera or camcorder/video recorder), a touch screen, a speaker, or the like.
