Abstract

Provided is a testing method including: disposing a wafer on a working platform of a testing device; and moving a circuit board of the testing device relative to the working platform by a movement assembly of the testing device so as to allow at least two testing ports of the circuit board to test two chips of the wafer, respectively. Further, the two testing ports have different testing functions. Therefore, during the wafer testing process, a single testing device can perform multiple testing operations.
