Abstract:
A circuit board or each circuit board of a multi-layer circuit board includes an electrically conductive sheet coated with an insulating top layer covering one surface of the conductive sheet, an insulating bottom layer covering another surface of the conductive sheet and an insulating edge layer covering an edge of the conductive sheet. An insulating interlayer can be sandwiched between a pair of adjacent circuit boards of a multi-layer circuit board assembly. A landless through-hole or via can extend through one or more of the circuit boards for connecting electrical conductors on opposing surfaces thereof.
Abstract:
A low profile integrated module (21, 22, 23) is fabricated to include sheets (25) of material, such as ceramic or PCB, fixed together and including a via (32) extending through at least one of the plurality of sheets from the lower module surface partially to the upper module surface and in a side module surface. The via is filled with conductive material. The module is then mounted on a supporting substrate having a solder pad on the mounting surface with an area greater than the lower surface of the via. The lower surface of the via is positioned adjacent the upper surface of the mounting pad and soldered so that solder wicks up the via along the side module surface.
Abstract:
The invention relates to a semiconductor component comprising a surface metallization. Said component has at least one semiconductor body (3) and a housing base body (2), on whose surface conductor strip structures (7) are formed by means of surface metallization. A partial zone of the conductor strip structures (7) constitutes the solder connections (1) of the semiconductor element. Said solder connections (1) are combined to form rows, whereby the individual solder connection rows are separated from one another by short, predetermined intervals.

Each component unit is mounted on the main printed-wiring board, covering one first electronic component (18). Each second conductor pattern is electrically connected to the first conductor pattern.
Abstract:
Described herein are devices, systems and methods for accessing devices, such as modules or printed circuit boards (PCBs), for electrical communications. Various connectors described herein utilize a side-edge surface of a device, such as a PCB, for connectivity in order to maximize the surface area on the PCB upon which electronic components can be mounted. Such connectors can be used to temporarily connect to devices (e.g., PCBs) for the purposes of debugging, testing and/or configuring circuitry, firmware and/or software. Each such connector utilizes the side-edge surface of a device along its thickness to provide connectivity, which is useful in many situations, including when the device (e.g., a PCB) is to be soldered as a part onto a larger board at a later point in time, or where multiple PCBs are stacked.
