<p><P>PROBLEM TO BE SOLVED: To provide a printed circuit board connecting method in which connection in the mutually perpendicular direction is enabled and in which high reliability can be obtained in terms of vibration and temperature of a movement means or the like. <P>SOLUTION: This has a constitution that a first electrode 206 formed on a surface of a plurality of holes 205 installed at a first printed circuit board 201, a protrusion 207 installed at a second printed circuit board 202, and a second electrode 208 composed of metal or metal compound installed at its surface, and that by inserting the protrusion 207 into the hole 205 in a state that a low melting point metal paste is adhered to a surface of the second electrode 208, and by cooling the both boards after heating, the first printed circuit board 201 and the second printed circuit board 202 in the perpendicular direction are mechanically and electrically connected, and since the first electrode 206 and the second electrode 208 are strongly connected electrically and mechanically, the high reliability can be obtained. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
