Within the limitations implicit in the magneto-quasi-static approximation, partial inductances are a valuable tool for modeling IC package and interconnect inductances. In the calculation of partial inductances it is not possible to directly apply the image theory due to the absence of charges on the ground plane. In the present paper a correction term is obtained, which allows to calculate partial inductances with the image theory, avoiding in this way the problem of the ground plane segmentation. The formula is valid for conductors parallel to the ground plane. The accuracy of the formula is verified and discussed.
