Abstract: An automatic testing method to be used by an IC testing system equipped with multiple testing sites. In this method the testing procedural information for each IC is stored in different sets of image files that are to be read by the testing system. Thus by inputting into the testing system the identification codes of the IC's that are going to be tested, the testing system would recognize which image files to use and the testing procedure would continue automatically. This method would greatly reduce the complex procedures needed to prepare an IC for testing in the prior art, thus leaving less room for human error and increasing the accuracy of the testing procedure.
