ABSTRACT:
A method for analyzing final test parameters includes the following steps: To retrieve the final test parameters of each product lots by searching a database. To compare the final test parameters to select a representative final test parameter and a representative final test item. To determine if the representative final test item is correlated to a packaging process step. To classify the plurality of product lots into at least a first qualified group and a first failed group according to the representative final test item if there is correlation. To search for the equipment through which the first qualified group or the first failed group had passed in the packaging process step. To determine the equipment having a probability of having processed the first failed group being greater than a probability of having processed the first qualified group.
