    摘要: A printed circuit board (PCB) with compound via includes a substrate and a pair of through holes passing through the substrate. The substrate includes a signal layer which is the top layer of the substrate, a first reference layer adjacent to the signal layer, and a second reference layer not adjacent to the signal layer. A first and a second pair of pads are mounted on the signal layer. Each of the through holes extends through the first pair of pads such that the through hole and the first pair of pads jointly form a compound via. A first reserved opening is formed on the first reference layer and corresponds to the first and the second pair of pads and the compound via. A second reserved opening is formed on the second reference layer and surrounds the through hole thereon.

    摘要: A computing system includes a drawing unit and a layout unit. The computing system sets components parameters to components of a circuit diagram of a printed circuit board (PCB). The drawing unit draws the circuit diagram by using the components with the components parameters. If the drawing unit wants to use a component more than once, the computing system copies the component and the corresponding components parameters. The drawing unit uses the copied components and the corresponding parameters. If the circuit diagram has been drawn, the layout unit loads the circuit diagram and wires the PCB according to the components and the components parameters in the circuit diagram.

    摘要: A robot arm includes a circular rack, an elongated first mounting member attached to the rack, and a second mounting member attached to the first mounting member. The first mounting member extends in a radius direction of the rack and moves in a circular trace along the rack. The second mounting member slides relative to the first mounting member along the radius direction, thereby defining a polar coordinate system in a plane defined by the rack to allow the second mounting member to flexibly locate at any desired positions in the plane.

    摘要: A printed circuit board (PCB) includes two layers, two signal transmission traces, and a vertical interconnect access (via). The signal transmission traces are respectively arranged on the layers. The signal transmission traces are electrically connected to each other through the via. A centerline of the via with a vertical line of the layers form an acute angle θ, the angle θ is less than cos−1[(Lv2−Lt2)/(Lv2+Lt2)]. Wherein Lt is loss of the two signal transmitting traces in a unit length, and Lv is loss of the via in a unit length.
