Claim:
1. An assembly method of direct-docking probing device, comprising the steps of: providing a space transforming plate which is made by a back-end-of-line semiconductor manufacturing process; providing a reinforcing plate which has larger mechanical strength than the mechanical strength of the space transforming plate, and a plurality of circuits disposed in the reinforcing plate; joining and electrically connecting the reinforcing plate and the space transforming plate by reflowing so as to form a space transformer; providing a conductive elastic member; providing a probe interface board and mounting the space transformer and the conductive elastic member on the probe interface board, wherein the conductive elastic member is located between and electrically connected with the probe interface board and the reinforcing plate, and the probe interface board is mounted on a test head; providing at least one vertical probe assembly having a plurality of vertical probes; and mounting the at least one vertical probe assembly on the space transforming plate, wherein the vertical probes is electrically connected with the space transforming plate; wherein the thickness of the space transforming plate is smaller than 1.8 mm and predetermined or configured by the client of the probe card manufacturer instead, and the thickness of the reinforcing plate is larger than 1.0 mm; wherein the conductive elastic member is disposed between the probe interface board and the reinforcing plate, and the conductive elastic member is disposed on the one side of the reinforcing plate, that is away from the space transforming plate; wherein the reinforcing plate is disposed between the conductive elastic member and the space transforming plate.
