摘要:
Ein Multi-LED System weist einen Träger (2) und mehrere Leuchtdioden (3, 3`, 3``) auf, die auf dem Träger (2) angeordnet sind. Der Träger (2) umfasst einen Grundkörper (4), in dem mehrere elektrische Bauelemente (11, 11`, 11``, 12) eingebettet sind. Beispielsweise weist der Grundkörper (4) ein Harz- und/oder Polymermaterial auf. Es kann sich bei dem Multi-LED System (1) insbesondere um ein vierfach LED Flash Modul handeln.

Disclosed are highly scalable fabrication methods for producing electronic circuits, devices, and systems. In one aspect, a fabrication method includes attaching an electronic component at a location on a substrate including a flexible and electrically insulative material; forming a template to encase the electronic component by depositing a material in a phase to conform on the surfaces of the electronic component and the substrate, and causing the material to change to solid form; and producing a circuit or electronic device by forming openings in the substrate to expose conductive portions of the electronic component, creating electrical interconnections coupled to at least some of the conductive portions in a selected arrangement on the substrate, and depositing a layer of an electrically insulative and flexible material over the electrical interconnections on the substrate to form a flexible base of the circuit, in which the produced circuit or electronic device is encased in the template.

The method comprises providing a semiconductor substrate (1), which has a main surface (12) and an opposite further main surface (13), arranging a contact pad (19) above the further main surface, forming a through-substrate via (4) from the main surface to the further main surface at a distance from the contact pad and, by the same method step together with the through-substrate via, forming a further through- substrate via (14) above the contact pad, arranging a hollow metal via layer (5) in the through-substrate via and, by the same method step together with the metal via layer, arranging a further metal via layer (15) in the further through- substrate via, the further metal via layer contacting the contact pad, and removing a bottom portion of the metal via layer to form an optical via laterally surrounded by the metal via layer.

A surge protector for protecting telecommunications related equipment and other associated sensitive electrical components from over- voltage transient occurring on tip/ring conductors of communication lines coupled thereto includes a printed circuit board and surge protection circuits mounted on the printed circuit board. The surge protection circuits are interconnected between incoming tip and ring terminals defining an unprotected side and outgoing tip and ring terminals defining a protected side. Each of the surge protection circuits has a first set of steering diodes, a pair of series-connected voltage clamping devices, and a second set of steering diodes. Input side connector devices are coupled to the respective incoming tip and ring terminals for connecting to incoming telecommunication lines. Output side connector devices are coupled to the respective outgoing tip and ring terminals for connecting to customers' electrical equipment to be protected.

An interconnect device is provided with a body through which a plurality of wells has been defined. At least one component having two terminals is provided in one or more of the wells. The component is sealed in its respective well such that the two terminals are accessible on opposite sides of the body. The body corresponds to a Ball Grid Array (BGA) device and is positioned between a BGA device and a printed circuit board (PCB). The component in the well is then inline with a solder ball on the BGA device and a corresponding pad on the PCB. Providing the component in the well frees up surface area on the PCB and also allows for positioning the component closer to a source of a signal. A component in the well is a discrete component having two terminals that may be solderable or made from a conductive pliable material. The terminals may be spring-mounted on the component.

A surge protection circuit may include a tuned circuit board with traces designed to provide a surge protected and RF isolated DC path while propagating RF signals through the PCB dielectric with microstrip lines. The surge protection circuit utilizes high impedance RF decoupling devices such as quarterwave traces or inductors which isolate the multistage DC protection scheme which may include a gas discharge tube, serial surge impeding devices such as inductors and/or resistors, a decoupled air/spark gap device and a Zener diode junction.
