<p>PROBLEM TO BE SOLVED: To prevent latching up which occurs when an electronic component mounting board is inserted into a connector, and to raise reliability of products. SOLUTION: On both surfaces of an SBC board 1 used for a personal computer, a plurality of electrodes 1a are formed near one major side. The electrodes 1a are provided with a power source voltage electrode 1a1 to which a power source voltage VCC is connected, and a reference potential electrode 1a2 to which a reference potential VSS is connected, respectively. A signal electrode 1a3 into/from which various signals are inputted/outputted is provided between the electrodes 1a1 and 1a2 . The electrodes 1a1 and 1a2 are longer than another signal electrode 1a3 so as to protrude about 1/3. So, when the electrode 1a of the SBC board 1 is inserted in an edge connector 3, the electrodes 1a1 and 1a2 contact first to a corresponding terminal 3a of the edge connector 3.</p> |
