Description
BACKGROUND
Field of the Invention

The field relates to an electronic component, and, in particular, to an electronic component with partially insulated leads, and particularly a staple lead inductor, and moreover, to a component-on-package (CoP) arrangement incorporating such a component.


Description of the Related Art

It is common to provide an integrated circuit, or a circuit formed of discrete components, in a single sealed package having a standardized terminal configuration (e.g., ball grid array, in-line pins, surface mount leads, etc.). The terminals of the package are typically then soldered to a printed circuit board along with other packages and components. Relevant factors in a package design may include for example size, terminal count, heat dissipation, current/voltage requirements, and electrical/magnetic interference issues.


For certain applications, some electronic devices provide electrical interconnections with increased power and current capabilities, as well as a reduced footprint on the system board to which the electronic device is mounted. For example, US Patent Publication Nos. US 2017/0311447 (filed Apr. 24, 2017, hereinafter “the '447 Publication”); US 2019/0141834 (filed Oct. 19, 2018); US 2019/0304865 (filed Oct. 4, 2018); and US 2020/0152614 (filed Nov. 12, 2019; hereinafter “the '614 Publication”) provide various examples of such electronic devices, the entire contents of each of which are incorporated by reference herein in their entirety and for all purposes. For example, some packages similar to those described in the '447 Publication utilize an internal leadframe architecture which can be used to provide an electrical and thermal interconnect between the substrate, inner components, and external components. Other electronic devices can use vertical interconnects like those described in the '614 Publication to provide high power electrical interconnection between a component and a substrate of an underlying package. However, it can be challenging to form a reliable electrical connection between the component and the underlying substrate. Accordingly, there remains a continuing need for improved electrical connection between an externally attached (CoP) component and an underlying substrate.

DETAILED DESCRIPTION


FIG. 1 is a schematic perspective view of an electronic device 1 comprising a component 40 mounted on a package 44. FIG. 2 is a schematic perspective view of the electronic device 1 of FIG. 1, with a molding compound 41 shown as transparent for ease of illustration. In the illustrated embodiment, the component 40 comprises a high power inductor for a switching regulator. The package 44 can comprise an integrated device package having one or a plurality of integrated device dies 14 mounted to a substrate 48.


The substrate 48 can comprise any suitable type of package substrate, e.g., a printed circuit board (PCB), a leadframe, a ceramic substrate, etc. The integrated device dies 14 can comprise any suitable type of electronic chip and can be electrically connected to the substrate 48. In various embodiments, for example, the integrated device die(s) 14 can be flip chip mounted to the substrate 48, e.g., by way of solder balls. In other embodiments, the integrated device die(s) 14 can be adhered and wire bonded to the substrate 48. It should be appreciated that one or more other types of components (such as passive electronic devices like resistors, capacitors, inductors, etc.) may additionally or alternatively be mounted and electrically connected to the substrate 48.


The molding compound 41 can comprise an insulating encapsulant, such as an epoxy, that is applied over the die(s) 14 and an upper surface of the substrate 48. The molding compound 41 can serve to protect the die(s) 14 and other components mounted to the substrate 48. As shown, a bottom surface of the component 40 can be mounted (e.g., adhered with epoxy) to a top surface of the molding compound 41 of the bottom package 44, using, for example, an epoxy 47 (see FIG. 3). The component 40 can electrically connect to one or more conductive pads 46 on the substrate 48 of the package 44 by way of a corresponding one or more holes 43 provided through the molding compound 41. For example, in the illustrated embodiment, the holes 43 can comprise laser drilled holes formed by irradiating the molding compound 41 with a laser to expose the conductive pads 46 on the substrate 48. In the illustrated embodiment, the holes 43 comprise elongated slots, which can have a rectangular shape. In other arrangements, similar holes can be provided through other insulating materials, such as FR4 insulating layers, e.g., for direct mounting of the component 40 into a receiving slot on a system board.


The component 40 can comprise one or a plurality of leads 42 extending downward from the component 40 and through the holes 43. In the illustrated embodiment, the leads 42 can comprise staple leads, e.g., thin and wide leads that are good conductors for high currents and heat. In one embodiment, the component 40 can comprise an inductor encased in a ferrite material which is highly thermally conductive. In other embodiments, the component 40 can comprise a transformer, or other suitable type of electrical component. In the illustrated embodiment, two staple leads 42 are illustrated along one side of the electronic device 1, but it should be appreciated that the opposing side of the electronic device 1 may also include an additional two leads 42 (not shown in FIGS. 1-2). The four leads 42 of the illustrated embodiment represent two staple lead inductors with a common ferrite body, but the skilled artisan will appreciate that principles and advantages taught herein are applicable to components having 2, 4, 6, 8 or any even number of staple leads. (See for example FIGS. 5-6 as discussed herein.) The leads 42 can extend through the holes 43 in the bottom package 44 and may or may not abut the metal pads 46 formed on the substrate 48 of the bottom package 44. In the embodiments of FIGS. 2 and 3, the leads 42 do not directly contact the metal pads 46; rather, electrical contact is made by way of an intervening conductive adhesive. For example, the holes 43 can be partially filled with a conductive material 45 (e.g., solder) that reflows and adheres to the pads 46 and the leads 42 to provide an electrical, thermal, and mechanical connection between the component 40 and the pads 46. In the illustrated embodiment, the conductive material 45 also provides electrical, thermal and mechanical connection between the component and the substrate 48 of the package 44.


In the electronic device 1 shown in FIGS. 1 and 2, the leads 42 can comprise a conductive material along the entire length of the lead 42. When the leads 42 of FIGS. 1 and 2 are soldered to the conductive pads 46 of the substrate 48, the conductive material 45 (e.g., solder) can wick upwardly along the conductive material of the lead 42. Excessive upward wicking of the conductive material 45 can vertically spread and thin the conductive material 45 between the lead 42 and the pad 46 and reduce reliability of the resulting solder joint.



FIG. 3 is a schematic side sectional view of an electronic device 1 according to one embodiment. FIG. 4 is a schematic end view of a component 40 that includes an inductor that can be used in the electronic device 1 of FIG. 3, shown separate from the substrate 48. Unless otherwise noted, the components of FIG. 3 may be the same as or generally similar to like-numbered components of FIGS. 1-2. For example, the electronic device 1 can include the integrated device package 44 and the component 40 mounted to the integrated device package 44, for example, with an adhesive 47. Although not shown in FIG. 3, the package 44 can comprise one or a plurality of devices, such as the integrated device dies 14 (FIG. 2), mounted to the substrate 48. The molding compound 41 can be provided over the dies 14 and portions of the upper surface of the substrate 48. The molding compound 41 can at least partially define a package body. As explained above, a hole 43 can be formed through the package body (e.g., the molding compound 41). In other embodiments, the hole 43 can be formed through any insulating material of a receiving carrier, such as a system board, to expose a contact pad to be contacted by the component leads.


The component 40 can comprise a component body 55 and a lead 42 extending from the component body 55 through the hole 43. In the illustrated embodiment, the lead 42 can include an insulated portion 49 and a distal exposed portion 50 below the line labeled “S&T line” in FIG. 3. The insulated portion 49 can include a conductor 56 and an insulating layer 57 disposed about the conductor 56. As shown, the distal exposed portion 50 can be uncovered by the insulating layer 57 such that the conductor 56 is exposed at the distal portion. A conductive material 45 (e.g., solder) can electrically connect the distal exposed portion 50 (e.g., the conductor 56) to the conductive pad 46 of the substrate 48. In FIG. 3, the conductive material 45 is shown in a reflowed state (e.g., after a solder reflow process).


In various embodiments, the insulating layer 57 can comprise a coating, and particularly a polymer layer, such as polyimide, although other insulating materials may be used. In some embodiments, the insulating layer 57 can be deposited over the conductor 56 as a coating, as opposed to a native insulating material. The insulating layer 57 can have any suitable thickness to serve the function of preventing excessive wicking without interfering with the conductor 56 electrical function (e.g., inductance). For example, the insulating layer 57 can have a thickness between about 0.01 mm and 0.10 mm, more particularly between about 0.06 mm and 0.09 mm. The insulating layer 57 is formed over the conductor 56, including both a horizontal electrode portion 58 of the conductor 56 (not shown) and vertical lead 42 portions of the conductor 56, prior to embedding (e.g., by molding) the horizontal electrode portion 58 (see FIG. 4) in the component body 55, which is a ferrite material 59 for the illustrated inductor embodiment. As shown in FIG. 4, the insulated lead 42 turns inwardly about 90° at the top of the lead 42 to form the horizontal inductor electrode 58 extending continuously through the component body 55 (into the page in the view of FIG. 3), and is bent about 90° downwardly to form a similar lead 42 on the other side of the component body 55. Thus, unlike conventional inductors, the staple lead inductor of the illustrated embodiment does not include any coils or turns within the ferrite body.


The conductor 56 can comprise any suitable metal. For example, in various embodiments, the conductor 56 can comprise copper. As shown, the distal exposed portion 50 can be formed by stripping a distal portion of the insulating layer 57 to expose the conductor 56. The insulating layer 57 can be stripped to a terminal edge 53 of the remaining portion of the insulating layer 57 (also referred to as a “strip and tinned lines,” or “S&T line” in FIG. 3). In some embodiments, the conductor 56 can be plated with a solderable material (e.g., tin) before being coated with the insulating layer 57. In the illustrated embodiment, the distal exposed portion 50 of conductor 56 is plated with the solderable material (or “tinned”) after stripping the distal portion of the insulating layer 57.


As shown in FIG. 3, during a reflow process, the conductive material can be provided in the hole 43 to a solder paste fill line 45′ prior to reflow. After reflow, the increased temperature can cause flux, solvents, and other materials to evaporate, and the conductive material 45 can harden within the hole 43 at a location substantially below the fill line 45′. During reflow, if the terminal edge 53 of the insulating layer 57 is placed too high relative to the solder fill line 45′, then the solder may wick upwardly along the conductor 56 and risk insufficient material for electrical, mechanical and thermal connection between the lead 42 and the pad 46. By contrast, if the terminal edge 53 of the insulating layer 57 is placed too low relative to the fill line 45′, then the solder may react with the insulating material of the insulating layer 57 to produce solder beads 51. Solder beads 51 can migrate during or after the reflow process and produce reliability problems for the electronic device 1. For example, the solder beads 51 may cause shorts between conductive components of the electronic device 1, crosstalk, or other problems.


The terminal edge 53 of the insulating layer 57 can be positioned at a height relative to a bottom surface 54 of the component body 55 and the solder fill line 45′ that is sufficiently low so as to prevent the conductive material 45 from wicking upwardly during reflow and the attendant reliability problems associated with wicking. Moreover, the terminal edge 53 of the insulating layer 57 can be placed sufficiently high relative to the bottom surface 54 of the component body 55 and the solder fill line 45′ so as to prevent the formation of solder beads 51 caused by the reaction between the insulating layer 57 and the conductive material 45 during reflow.


In the illustrated embodiment, the distal exposed portion 50 of the lead, which is preferably also tinned, extends from a distal end 52 of the lead 42 to the terminal edge 53 of the insulating layer 57. The insulating portion 49 can extend from the component body 55 to the terminal edge 53, but the insulating sleeve or layer 57 also coats the extension of the electrode from the lead 42 through the component body and to the lead 42 on the other side of the component body 55. The terminal edge 53 can be disposed at or above the bottom surface 54 of the component body 55. For example, the terminal edge 53 can be disposed at a distance in a range of 0 mm to 2 mm above the bottom surface 54 of the component body 55, e.g., at a distance in a range of 0 mm to 1.2 mm above the bottom surface 54 of the component body 55, in a range of 0.1 mm to 1.2 mm above the bottom surface 54 of the component body 55, in a range of 0.25 mm to 1.2 mm above the bottom surface 54 of the component body 55, or in a range of 0.5 mm to 1.2 mm above the bottom surface 54 of the component body 55.


As shown, the distal end 52 of the lead 42 can be spaced above the conductive pad 46 such that the distal end 52 does not contact the conductive pad 46. The spacing between the conductive pad 46 and the distal end 52 of the lead 42 can be controlled by the design of the component 40 itself (including the component body 55 and lead 42 geometries), the thickness of the package molding compound 41 or other insulating layer in which the hole 43 is formed, and the thickness of the adhesive (epoxy 47) between the component 40 and the underlying package 44 or other carrier. Such spacing can improve the planarity of the component 40 after mounting in some embodiments. The conductive material 45 can span the gap to electrically, mechanically and thermally connect the conductor 56 and the pad 46.


As explained above, in the illustrated embodiment, the component 40 comprises an inductor. The inductor can comprise a conductive material 60 and a ferrite material 59 in which the conductive material 60 is encased. Further, the inductor can comprise a staple lead inductor having a straight electrode within the ferrite component body 55 (i.e., no coil, representing a single turn in some embodiments). The leads 42 of the staple inductor can be sufficiently wide so as to convey a large amount of current for high power applications. For example, in some embodiments, the component 40 can be operated at high and low currents, e.g., at currents in a range of 0.1 A to 250 A, e.g., in a range of 5 A to 100 A (e.g., at least 1 A or at least 5 A). The inductor can have any suitable inductance, e.g., an inductance in a range of 10 μH to 100 mH. The component 40 can also have any suitable size. In various embodiments, the component 40 can have a vertical height in a range of 1 mm to 20 mm, or in a range of 3 mm to 9 mm.



FIG. 3 illustrates one lead 42, but it should be appreciated that the component 40 (e.g., an inductor) can comprise a plurality of leads 42 (e.g., 2, 4, 6, 8 or more) as shown in FIG. 4. For example, in some embodiments, the package 44 or other carrier can comprise a second hole 43 (not shown) and the component 40 comprises a second lead 42 (shown in FIG. 4) extending into the second hole 43 to electrically connect to a second conductive pad 46 (not shown) of the substrate 48. The second lead 42 may be the same as or generally similar to the lead 42 shown in FIG. 3, and may extend from an opposite end of the horizontal electrode portion 58 of the conductor embedded in the component body 55. For example, the second lead 42 can comprise an insulated portion 49 and a second distal exposed portion 50. The insulated portion 49 can include a segment of the conductor 56 and the insulating layer 57 disposed about the conductor 56. The second distal exposed portion 50 can be uncovered by the insulating layer 57.



FIGS. 5-6 each illustrate another embodiment of the electronic device 1 shown in FIG. 1. The previously described lead design structures can be applied to, but not limited to, externally attached components with multiple leads (FIG. 5). Moreover, the foregoing structures are not restricted to only inductor designs, but may also include transformers, other passive components, and active DFN and/or QFN power packages, as well as external components like heatsinks, RF shielding structures, and anything with leads formed for insertion into the mold compound vias to make electrical and thermal connections to the substrate pads. As shown in FIG. 5, the electronic device 1 includes a component 40 with eight (8) leads 42 (four of the leads 42 not shown). Other corresponding parts of the electronic device 1 in FIG. 5 may be the same or generally similar to those described herein with respect to FIGS. 1-4. Furthermore, the foregoing design is not limited to devices comprised of only one externally attached device but can also apply to packages with multiple attached components with a multitude of lead arrangements (e.g., side-to-side, end-to-end, end-over-end, etc.) (see FIG. 6). As shown in FIG. 6, the electronic device 1 includes two (2) components 40 each with four (4) leads 42 (two of the leads 42 of each component not shown). Other corresponding parts of the electronic device 1 in FIG. 6 may also be the same or generally similar to those described herein with respect to FIGS. 1-4.


Although disclosed in the context of certain embodiments and examples, it will be understood by those skilled in the art that the present invention extends beyond the specifically disclosed embodiments to other alternative embodiments and/or uses and obvious modifications and equivalents thereof. Further, unless otherwise noted, the components of an illustration may be the same as or generally similar to like-numbered components of one or more different illustrations.
