One set of data, depending upon how it is analyzed, can actually provide different values for the index being investigated. For example, if one is interested in the capability of the process for meeting the specifications on one particular component, different results could be obtained if the data were analyzed in the following ways: board-to-board, all deposits, parallel vs. perpendicular pad orientation (w.r.t. squeegee blade direction), and others.
This paper will provide an example case study and show that one process, depending upon how it is viewed or analyzed, will in fact produce various results via process capability index analysis.
