<p><P>PROBLEM TO BE SOLVED: To alleviate stress applied to a junction part of an electronic device mounted on a print circuit board. <P>SOLUTION: A corner part terminal 2b of an electronic device 2 including a terminal arranged in a matrix form does not covey an electric signal. A land 3 that electrically connects the corner part terminal 2b to the other terminal 2a of the electronic device 2 and has a matrix form is provided in a print circuit board 1, and a through hole 4 is provided in a location facing the corner part terminal 2b. Therefore, stress concentration in a junction part of the electronic device 2 is reduced, thereby avoiding the risk of breakage. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
