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.

A printed circuit board for mounting an electronic part, the printed circuit board comprising:
- a plurality of pins arranged on the board to form a generally polygonal shape for being electrically connected to the electronic part, the plurality of pins including at least two first pins as ground terminals and at least two second pins as source terminals, the ground terminals being disposed at a corner portion of the generally polygonal shape and being non-parallel relative to one another, the source terminal adjoining the ground terminals;
- and
- a first conductive region provided on the board and extending radially from the corner portion of the polygonal shape and electrically and directly connected to the ground terminals with no additional conductive path between the first conductive region and the ground terminals.
