Claim Text:
1. A three-dimensional backplane, comprising: a first group of electrical connectors, a second group of electrical connectors, a first group of printed circuit boards, and a second group of printed circuit boards, wherein: the first group of electrical connectors comprises at least two electrical connectors; the second group of electrical connectors comprises at least two electrical connectors; the first group of printed circuit boards comprises at least two printed circuit boards, or the second group of printed circuit boards comprises at least two printed circuit boards; the first group of connectors is disposed on the first group of printed circuit boards; the second group of connectors is disposed on the second group of printed circuit boards; each printed circuit board in the first group of printed circuit boards is connected to all printed circuit boards in the second group of printed circuit boards; each printed circuit board in the second group of printed circuit boards is connected to all printed circuit boards in the first group of printed circuit boards; each electrical connector in the first group of electrical connectors is connected to all electrical connectors in the second group of electrical connectors through all connections between a printed circuit board, where the electrical connector is disposed, in the first group of printed circuit boards and all printed circuit boards in the second group of printed circuit boards; each electrical connector in the second group of electrical connectors is connected to all electrical connectors in the first group of electrical connectors through all connections between a printed circuit board, where the electrical connector is disposed, in the second group of printed circuit boards and all printed circuit boards in the first group of printed circuit boards; wherein: when the first group of printed circuit boards comprise at least two printed circuit boards, all printed circuit boards in the first group of printed circuit boards are parallel to each other; and when the second group of printed circuit boards comprises at least two printed circuit boards, all printed circuit boards in the second group of printed circuit boards are parallel to each other; wherein the first group of printed circuit boards are perpendicular to the second group of printed circuit boards; wherein the three-dimensional backplane further comprises a fixing board; and wherein the first group of printed circuit boards and the second group of printed circuit boards are fixed on the fixing board.
