    摘要: Electronic substrates, contact pads for electronic substrates, and related methods are disclosed. Electronic substrates may include an electrically conductive layer that forms at least one contact pad and at least one metal trace on a non-conductive layer. The contact pads are arranged with greater thicknesses or heights above the non-conductive layer than the metal traces. Dielectric layers are disclosed that cover the metal traces while leaving top surfaces of the contact pads exposed. Top surfaces of the dielectric layers may be arranged to be coplanar with top surfaces of the contact pads to provide electronic substrates having generally planar top faces. Bottom faces of electronic substrates may include mounting pads that are coplanar with additional dielectric layers. Methods are disclosed that include forming dielectric layers to cover contact pads and metal traces, and removing surface portions of the dielectric layers until the contact pads are accessible through the dielectric layers.

    摘要: This disclosure relates generally to substrates having three dimensional (3D) inductors and methods of manufacturing the same. In one embodiment, the 3D inductor is a solenoid inductor where the exterior edge contour of the winding ends is substantially the same and substantially aligned with the exterior edge contour of the exterior edge contour of conductive vias that connect the windings. In this manner, there is no overhang between the windings and the conductive vias. In another embodiment of the 3D inductor, via columns connect connector plates. The via column attachment surfaces of each of the conductive vias in each of the columns is the same and substantially aligned. In this manner, carrier pads are not needed and there is no overhand between the conductive vias.

    摘要: Laminate structures and configurations of fiducials for laminates structures for electronic devices are disclosed. Fiducials are formed in laminate structures to provide increased visibility and contrast, thereby improving detection of the fiducials with optical detection equipment of automated machines commonly used in the electronics industry. Fiducials are disclosed that are defined by openings in laminate structures that extend to depths within the laminate structures to provide sufficient contrast. Openings for fiducials may be arranged to extend through multiple metal layers and dielectric layers of the laminate structures. The fiducials may be formed by laser drilling or other subtractive processing techniques. Fiducials as disclosed herein may be coated with additional layers or coatings, such as a metal coating that includes an electromagnetic shield for electronic devices, and the fiducials are configured with sufficient visibility and contrast to remain detectable through the additional layers or coatings.

    摘要: Embodiments of electronic devices, such as integrated circuit (IC) packages are disclosed. In one embodiment, an electronic device includes a first substrate and a second substrate. The first substrate has a first substrate body and a first inductor portion integrated into the first substrate body. Additionally, the second substrate comprises a second substrate body and a second inductor portion integrated into the second substrate body. The second substrate is mounted on the first substrate such that such that the second inductor portion is positioned over the first inductor portion and such that the second inductor portion is electrically connected to the first inductor portion so that the first inductor portion and the second inductor portion form a three dimensional (3D) inductor. By using two substrates, the 3D inductor can be increased in height while still allowing the substrates to be miniaturized and standardized for an IC package.
