    摘要： A system and method for inspecting layout of a printed circuit board (PCB) provides a graphical user interface (GUI). The GUI displays a layout of the PCB. High side pins of a pulse width modulation (PWM) controller and a component connected to a high side pin are found. If the component is a metallic oxide semiconductor field effect transistor (MOSFET), the system calculate absolute a linear distance and a trace distance between a source pin of the MOSFET and a capacitor pin of a coupling capacitor connected to the source pin. If the linear distance, the trace distance and a capacitance of the coupling capacitor accord with a layout standard, the layout of the PCB is determined to be up to standard.

    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.

    摘要： Parameters of a radio frequency filter can be changed by changing structure of each component of the filter. Material of each component, diameters of each of magnetic cylinders, density of each of conductive coils, thickness of a dielectric layer, and thickness of an insulation tube can be changed. When any component needs to be replaced, each cover is rotated, with connection partitions move to two slots of a resisting portion, to detach the filter.

    摘要： A bearing includes a main body, a plurality of first magnetic members, a plurality of second magnetic members, and a plurality of friction members. The main body defines a pivot hole, and a plurality of first receiving portions and a plurality of second receiving portions around the pivot hole. Each of the second receiving portions defines a cutout. The first magnetic members are received in the first receiving portions. The second magnetic members together with the friction members are received in the second receiving portions, thus generating a repelling force between the first magnetic members and the second magnetic members to impel the friction members to partially extend out of the cutouts.
