Abstract:
This relates to systems and methods for providing one or more vias through a module of an electrical system. For example, in some embodiments, the module can include one or more passive elements and/or active of the electrical system around which a packaging has been plastic molded. The module can be stacked under another component of the electrical system. Vias can then be provided that extend through the module. The vias can include, for example, electrically conductive pathways. In this manner, the vias can provide electrical pathways for coupling the component stacked on top of the module to other entities of an electronic device including the electrical system. For example, the component can be coupled to other entities such as other components, other modules, printed circuit boards, other electrical systems, or to any other suitable entity.
Abstract:
According to one embodiment, an electrical interconnection system includes a pair of printed wiring boards formed of a printed wiring board material. Each printed wiring board has multiple surface pads formed on a surface of the printed wiring board adjacent its outer edge. The surface of each printed wiring board is operable to be placed adjacent to one another such that an electrical circuit coupled to one printed wiring board is electrically coupled to another electrical circuit of the other printed wiring board by contact of the surface pads of each printed wiring board with one another.

Structures employed by a plurality of packages, printed circuit boards, connectors and interposers to create signal paths which reduce the deleterious signal quality issues associated with the use of through-holes. Disclosed structures can coexist with through-hole implementations.
Abstract:
A circuit board includes an electrically conductive sheet having an insulative coating surrounding the conductive sheet, with a surface of the insulative coating around an edge of the conductive sheet having an arcuate or rounded shape. At least one electrical conductor is conformally deposited on at least the rounded insulative coating around the edge of the conductive sheet and defined via photolithographic and metallization techniques. Each electrical conductor on the insulative coating thereon around the edge of the conductive sheet conforms to the arcuate or rounded shape of the insulative coating and, therefore, has an arcuate or rounded shape.
Abstract:
Provided is a method of forming a circuit board including (a) providing a first conductive sheet; (b) selectively removing one or more portions of the first conductive sheet to form a first panel having a first circuit board that is coupled to a disposable part of the first panel by at least one tab that extends from an edge of the first circuit board to an edge of the disposable part of the first panel; (c) applying an insulating coating to the first circuit board so that at least each edge of the first circuit board is covered thereby; and (d) separating the first circuit board from the disposable part in a manner whereupon at least part of the tab remains attached to the first circuit board and includes an exposed edge of the conductive sheet of the first circuit board. Circuit boards formed by the method are also provided.

A printed circuit board and a method of manufacturing a printed circuit board are disclosed. Using a method of manufacturing a printed circuit board, which includes: forming a multilayer board by alternately stacking circuit pattern layers and insulation layers such that a predetermined thickness of a partial area has only insulation layers stacked therein; and removing insulation layers from the partial area of the multilayer board, a printed circuit board can be manufactured that is suitable for a slim module.
Abstract:
Disclosed is a method of manufacturing a hybrid structure of multi-layer substrates. The method comprises steps of: separating a border district of at least one metal layer connecting with a border district of the corresponding dielectric layer from adjacent metal layers and adjacent dielectric layers for each multi-layer substrate and connecting a separated border of a metal layer of one multi-layer substrate with a separated border district of a metal layer of another multi-layer substrate to form a connection section. The hybrid structure comprises at least a first multi-layer substrate and a second multi-layer substrate. At least one first metal layer is connected with at least one second metal layer to form a connection section.
Abstract:
The invention relates to circuit boards and to screening circuits and components on such boards from stray rf interference when they are mounted as arrays or stacks of such circuit boards. The circuit boards (12, 14) are individually screened by conductive screening layers (16, 18) as known in the art and the individual screening layers are coupled together by layered interconnects (34) which connect corresponding screening layers (16, 18) of the individual circuit boards (12, 14) together, instead of by vias.
Abstract:
A multilayer printed circuit board may include traces that are printed on selected layers of the board so that the traces extend to the edge of the corresponding layer. When the layers are assembled together, the ends of the traces may be viewable on a side of the printed circuit board. The traces may be arranged to convey information. For example, trace ends may be readable as one or more binary words, as alphanumeric characters or as a bar code.
Abstract:
A connecting substrate includes a first conductive member; an insulating layer; and a second conductive member, the first conductive member and the second conductive member facing each other via the insulating layer, in which wherein an end portion of either one of the first conductive member and the second conductive member extends past an end portion of the other conductive member and past an end portion of the insulating layer.
