Patent ID: 8653377

Claim:
A microelectronic assembly, comprising: a first circuit board having a first group of N electrical interconnects (L 1 through L N ) and second group of N electrical interconnects (M 1 through M N ), wherein a quantity J of the first group of N electrical interconnects (L 1 through L J ) of the first circuit board are consumed by a circuit component mounted on the first circuit board and the remaining N−J electrical interconnects of the first group of electrical interconnects (L J+1 to L N ) of the first circuit board are electrically coupled to the 1 through N−J (M 1 to M N−J ) electrical interconnects of the second group of N electrical interconnects on the first circuit board; a second circuit board having a first group of N electrical interconnects (L 1 through L N ) and second group of N electrical interconnects (M 1 through M N ); and a first coupling medium that couples the second group of N electrical interconnects (M 1 through M N ) of the first circuit board to the first group of N electrical interconnects (L 1 through L N ) of the second circuit board; wherein there is no backplane electrical interconnect extending between each of the circuit boards.
