Abstract:
Systems and methods described in this disclosure are related to fabrication and utilization of two-terminal electrical components that may have terminations with reduced width. Components, such as the ones described herein may be used to increase the density of components in electrical devices, as they may reduce a separation distance between devices that lead to solder bridging. Methods for fabrication are also described, including the use of ceramic layers that may provide reduction in parasitic capacitance and/or inductances.
Abstract:
Electronic devices may contain electrical systems in which electrical components are mounted on a substrate such as a printed circuit board. The electrical components may include surface mount technology components. Multiple surface mount technology components may be stacked on top of each other and beside each other to form an electrical component that minimizes the amount of area that is consumed on a printed circuit board. Noise suppression circuits and other circuits may be implemented using stacked surface mount technology components. Surface mount technology components placed on the printed circuit board may be pushed together and subsequently injection molded to form packed component groups. An integrated circuit may be mounted to the printed circuit board via an interposer and may cover components mounted to the printed circuit board. An integrated circuit may be mounted over a recessed portion of the printed circuit board on which components are mounted.
Abstract:
Electronic assembly methods and structures are described. In an embodiment, an electronic assembly method includes bringing together an electronic component and a routing substrate, and directing a large area photonic soldering light pulse toward the electronic component to bond the electronic component to the routing substrate.
Abstract:
Battery systems according to embodiments of the present technology may include a battery. The battery may include a first electrode terminal and a second electrode terminal accessible along a first surface of the battery. The systems may include a module electrically coupled with the battery. The module may include a circuit board characterized by a first surface and a second surface opposite the first surface. The module may include a mold extending from the first surface of the circuit board toward the battery. The module may include a first conductive tab electrically coupling the module with the first electrode terminal. The module may include a second conductive tab electrically coupling the module with the second electrode terminal. The second conductive tab may extend across the mold substantially parallel to the first surface of the circuit board.
Abstract:
Electronic devices may be provided with printed circuits to which integrated circuits and other electrical components may be mounted. A first printed circuit may have a first surface with an array of contact pads arranged in rows and columns. Each column of contact pads may have a series of contact pads separated by gaps. The contact pads in each column may be staggered with respect to the contact pads in adjacent columns such that each contact pad in a given column is horizontally adjacent to associated gaps in the adjacent columns. A component may be mounted to an opposing surface of the printed circuit such that it overlaps one of the gaps between the staggered contact pads. By mounting the component to portions of the first printed circuit that do not overlap the staggered contact pads, the risk of damaging the electrical component during solder reflow operations may be minimized.
Abstract:
An RF shield formed of RF opaque material that permits access to components on a printed circuit board is described. The RF shield can include a first portion attached to the PCB and a removable top portion attached to the first portion at an interface. The top portion is removed from the first portion to expose the components on the PCB. In one aspect of the described embodiment, the top portion is peeled away from the first portion. The components are enclosed within the RF shield after the removal of the top portion by attaching and sealing another top portion to the first portion at the interface by, for example, laser attaching the first portion and the other top portion at the interface.

Abstract:
Readily manufactured structures for sealing or encapsulating devices in system-in-a-package modules, such that the modules are easily assembled, have a low-profile, and are space efficient. One example may provide readily manufactured covers for SIP modules. These modules may be easily assembled by attaching the cover to a top side of a substrate. These SIP modules may have a low-profile, for example when their height is reduced using one or more recesses in a bottom surface of a top of the recess, where the one or more recesses are arranged to accept one or more components. These SIP modules may be made space efficient by placing an edge of a cover near an edge of the substrate and connecting the plating of the cover using side plating on, or vias through, the substrate.

Packages and methods of assembly are described in which barriers are utilized during overmolding to improve volumetric efficiency. In one embodiment, a barrier includes multiple variable height components located on an interior of the barrier, where the barrier prevents the variable height components from being overmolded during the encapsulation process. In one embodiment, a barrier includes a camera module mounted on an image sensor located on an interior of the barrier, where the barrier prevents the camera module and image sensor from being overmolded during the encapsulation process. In an embodiment, a barrier is mounted on a secondary tier with the secondary tier mounted on a primary tier, where the barrier prevents multiple connector components located on an interior of the barrier from being overmolded during the encapsulation process.
