PROBLEM TO BE SOLVED: To provide a print circuit board capable of increasing an area without changing a structure of an existing socket.SOLUTION: When a terminal of a bottom surface of a print circuit board 20 is connected to a socket for a rand grid array type package of a mother board 120, a positioning is performed by inserting rectangle corner parts 22AC, 22BC, 22CC, and 22DC of four corners of the print circuit board 20 into four L-shaped fixing tools 30A, 30B, 30C, and 30D for positioning to the socket. Side ends 20U, 20R, 20L, and 20D are extended to an outer side of a rectangle shape connecting the four rectangle corner parts 22AC, 22BC, 22CC, and 22DC. Therefore, an area of the print circuit board can be increased.SELECTED DRAWING: Figure 1 |
