    Abstract: A fan housing of a fan unit includes a housing wall standing from the surface of a printed circuit board. The printed circuit board serves to establish the fan housing in cooperation with the housing wall. The fan housing further includes a ceiling wall connected to the housing wall. The ceiling wall extends along a datum plane parallel to the surface of the printed circuit board. A high speed airflow can be generated within the fan housing. The airflow promotes the heat radiation from the printed circuit board. An electrically conductive wiring pattern extending over the surface of the printed circuit board may further promote the heat radiation from the printed circuit board.

    Abstract: A data bus of a DVD+RW recorder between a DSP and a SDRAM usually needs a multilayer wiring board. In order to simplify the layout of the wiring board of the data bus there is provided a method for connecting at least a first and a second integrated circuit by providing the first integrated circuit having a plurality of first logical I/O ports physically arranged in a first order at the periphery, and providing the second integrated circuit having a plurality of second logical I/O ports physically arranged in a second order at the periphery, wherein each first I/O port is to be connected to one of said second I/O ports. The first and second I/O logical ports are connected independently from the first and/or second physical order, so that connection lines do not cross each other.

    Abstract: Plural pins are arranged on a printed circuit board to form a generally square shape and are electrically connected to terminals of a QFP-IC. In the pins, a pin disposed at a corner portion of the generally square shape is used as a GND terminal, and a pin adjoining the GND terminal is used as a source terminal. A conductive region is provided to extend radially from the corner portion, and is electrically connected to the ground terminal. Further, another conductive region is provided in the generally square shape and is electrically connected to the radial conductive region.
