A flip chip package substrate is disclosed. The substrate is correspondingly flip chip bonded to a first chip, a second chip, and so on, wherein these chips are of similar type of pad arrangement but of different pad pitches. The top face of the flip chip package substrate is provided with a plurality of bump pad groups, and these bump pad groups are respectively provided with a plurality of bump pads in the sequence of a first bump pad, a second bump pad, and so on, and a plurality of bump pads of the same bump pad group are electrically connected with each other, and the positions of the first bump pads are respectively corresponding to the positions of the second pads, and the rest may be inferred by analogy. Hence, these chips share the same flip chip package substrate.
