Claim 4:
5. The cantilever probe card according to claim 1, wherein each of the probe modules includes:
a supporting board assembled to a corresponding one of the assembling regions of the carrying surface;
a substrate disposed on the supporting board, wherein the substrate has a non-planar shape and has a difference of warpage along the testing direction;
a plurality of cantilever probes, wherein one end of each of the cantilever probes is connected to the substrate, and another end of each of the cantilever probes is a needle tip; and
a plurality of fine adjustment members spaced apart from each other and disposed between the supporting board and the substrate, wherein each of the fine adjustment members is configured to be independently operable along the testing direction for changing a distance between the supporting board and the substrate;
wherein, in each of the probe modules, the substrate is deformable through at least one of the fine adjustment members so as to reduce the difference of warpage of the substrate along the testing direction.
