Abstract: A heat dissipation fan structure capable of showing a pattern of light includes a circuit board, a light guide plate, a light-permeable element, and a vane assembly sequentially connected together. The circuit board is provided with a light emission unit. The vane assembly has a light-permeable wall made of a light-permeable material. The light emitted by the light emission unit is evenly diffused by the light guide plate, passes through the light-permeable element, and is rendered into a specific pattern (e.g., a decorative design and/or characters) by the light-permeable portion of the light-permeable element, wherein the light-permeable portion is shaped according to user needs. The light-permeable material of the light-permeable wall of the vane assembly allows the decorative design and/or characters of light to be seen externally. The heat dissipation fan structure, therefore, can show a pattern of light in addition to dissipating heat.

Abstract: A disconnect cavity is formed within a PCB, where the disconnect cavity is electrically disconnected from a PCB landing layer. The disconnect cavity is formed using a plating resist process which does not require low flow prepreg nor selective copper etching. Plating resist is printed on a core structure selectively positioned within a PCB stack-up. The volume occupied by the plating resist forms a subsequently formed disconnect cavity. After lamination of the PCB stack-up, depth control milling, drilling and electroless copper plating are performed, followed by a plating resist stripping process to substantially remove the plating resist and all electroless copper plated to the plating resist, thereby forming the disconnect cavity. In a subsequent copper plating process, without electric connectivity copper cannot be plated to the side walls and bottom surface of the disconnect cavity, resulting in the disconnect cavity wall being electrically disconnected from the PCB landing layer.

Abstract: A printed circuit board (PCB) has multiple layers, where select portions of one or more conductive layers, referred to as core circuitry, form a semi-flexible PCB portion that is protected by an exposed prepreg layer. The semi-flexible PCB portion having an exposed prepreg layer is formed using a dummy core process that leaves the exposed prepreg layer smooth and undamaged. The core circuitry is part of a core structure. The semi-flexible PCB portion is an extension of the remaining adjacent multiple layer PCB. The remaining portion of the multiple layer PCB is rigid. The core structure is common to both the semi-flexible PCB portion and the remaining rigid PCB portion.

Abstract: A selective segment via plating process for manufacturing a circuit board selectively interconnects inner conductive layers as separate segments within the same via. Plating resist is applied to a conductive layer of an inner core and then stripped off after an electroless plating process. Stripping of the electroless plating on the plating resist results in a plating discontinuity on the via wall. In a subsequent electroplating process, the plug non-conductive layer can not be plated due to the plating discontinuity. The resulting circuit board structure has separate electrically interconnected segments within the via.

Abstract: A printed circuit board has multiple stacked layers laminated together. A through hole is formed through the laminated stack, and plating is applied to the side walls of the though hole, thereby forming a plated through hole. Second through holes are then formed through the laminated stack, where each second through hole overlaps an edge of the plated through hole. By aligning the second through holes at the edge of the plated through hole, the plating of the plated through hole coincident with each second through hole is removed, thereby separating the plated through hole into two separate circuit paths. Forming second through holes in this manner effectively splits the circuit path of the plated through hole into multiple separate circuit paths, which increases the circuit density of the printed circuit board.
