INTERCONNECTING BOARD AND PRODUCTION THEREOF, STRUCTURE COMPRISING BOARD, INTERCONNECTING BOARD AND FIXING BOARD, AND CONNECTOR BETWEEN BOARD AND INTERCONNECTING BOARD

摘要

PROBLEM TO BE SOLVED: To provide an interconnection board being interposed between an LGA board and a printed board in order to interconnect them easily, a production method therefor, a structure comprising a board, the interconnection board and a fixing board, and a connector for the board and the interconnection board. SOLUTION: An easily deformable soft metal body 206 is passed through a through hole made through an interconnecting board body 1 such that the soft metal body 206 projects from any one of the opposite surfaces (first and second surfaces) of the interconnecting board body with the projecting height being differentiated on the opposite surfaces thus producing an interconnecting board 209. The projecting height is set differently from that of the soft metal body 206 depending on the material and the coefficient of thermal expansion of an LGA board 220, a printed board 240 and the interconnecting board body 1 thus setting the interval A1 between the LGA board 220 and the interconnecting board body 1 and the interval A2 between the interconnecting board body 1 and the printed board 240 correctly.
