    Abstract: Systems and methods for simultaneously partitioning a plurality of via structures into electrically isolated portions by using plating resist within a PCB stackup are disclosed. Such via structures are made by selectively depositing plating resist in one or more locations in a sub-composite structure. A plurality of sub-composite structures with plating resist deposited in varying locations are laminated to form a PCB stackup of a desired PCB design. Through-holes are drilled through the PCB stackup through conductive layers, dielectric layers and through the plating resist. Thus, the PCB panel has multiple through-holes that can then be plated simultaneously by placing the PCB panel into a seed bath, followed by immersion in an electroless copper bath. Such partitioned vias increase wiring density and limit stub formation in via structures. Such partitioned vias allow a plurality of electrical signals to traverse each electrically isolated portion without interference from each other.

    Abstract: Disclosed is a printed circuit board including an electromagnetic bandgap structure. The electromagnetic bandgap structure, which includes a first dielectric material for interlayer insulation and is for blocking a noise, is inserted into the printed circuit board. The electromagnetic bandgap structure can include a first conductive plate, a second conductive plate arranged on a planar surface that is different from that of the first conductive plate, a third conductive plate arranged on a same planar surface as the first conductive plate, and a stitching via unit configured to connect the first conductive plate and the third conductive plate through the planar surface on which the second conductive plate is arranged. A second dielectric material having a permittivity that is different from that of the first dielectric material is interposed between any two of the first conductive plate, the second conductive plate, and the third conductive plate.

    Abstract: A method for forming a wire bonding substrate is disclosed. A substrate comprising a first surface and a second surface is provided. A through hole is formed in the substrate. A conductive layer is formed on the first surface and the second surface of the substrate and covers a sidewall of the through hole. The conductive layer on the first surface of the substrate is patterned to form at least a first conductive pad, and the conductive layer on the second surface of the substrate is patterned to form at least a second conductive pad. An insulating layer is formed on the first surface and the second surface of the substrate and covers the first conductive pad and the second conductive pad. The insulating layer is recessed until top surfaces of the first conductive pad and the second conductive pad are exposed. A first metal layer is electroplated on the first conductive pad by applying current from the second conductive pad to the first conductive pad through the conductive layer passing the through hole.

    Abstract: A new SMD (surface mount devices) package design for efficiently removing heat from LED Chip(s) is involved in this invention. Different from the regular SMD package, which electrical isolated materials like Alumina or AlN are used, the substrate material here is metal like Copper, Aluminum and so on. Also, different from regular design, which most time only has one LED chip inside, current design will at least have two or more LED chips (or chip groups) in one package. All chips are electrical connected via metal blocks, traces or wire-bond. This type of structure is generally fabricated via chemical etching and then filled with dielectric material inside to form a strong package. Because the thermal conductivity of the metal is much higher than the ceramics, the package thermal resistance is much lower than the ceramics based package. Also, the cost of the package is much lower than ceramics package. Moreover, emitting area in one package is much larger than the current arts.
