Patent ID: 6919227

Claim:
A method of mounting an interposer board to a printed circuit board, the interpose board comprising an outer circumferential side and an inner circumferential side, one or more area terminals arrayed on the outer circumferential side of the interposer board, and one or more area terminals arrayed on the inner circumferential side of the interposer board, the printed circuit board comprising an outer circumferential side and an inner circumferential side, one or more land terminals arrayed on the outer circumferential side of the printed circuit board, and one or more land terminals arrayed on the inner circumferential side of the printed circuit board, the method comprising: (a) applying a conductive bonding solution to at least one of the area terminals arrayed on the outer circumferential side, the area terminals arrayed on the inner circumferential side, the land terminals arrayed on the outer circumferential side, and the land terminals arrayed on the inner circumferential side; and (b) connecting the area terminal arrayed on the outer circumferential side to the land terminal arrayed on the outer circumferential side, and the area terminal arrayed on the inner circumferential side to the land terminal arrayed on the inner circumferential side; wherein the area terminal on the outer circumferential side is arrayed with a larger pitch than the area terminal on the inner circumferential side; and wherein the land terminal on the outer circumferential side is arrayed with a larger pitch than the land terminal on the inner circumferential side.
