【正文】 ?Vertical axe : Mean value of the measured data ?USL : Upper red line ?LSL : Lower red line ?Total mean : Dashed blue line Control Chart ? S Control Chart ?The S control chart is used to see the process dispersion by using the standard deviation S of each Subgroup. ?For n ≥ 11, S control chart is automatically selected. Control Chart ?The R control chart is used to see the process dispersion by using the range R of each Subgroup. ?For 2 ≤ n ≤ 10, the R control chart is automatically selected. ? R Control Chart Control Chart ?For n=1, the x control chart is used to manage the individual status of the measured values (height, area, volume, and offset) x of the selected pad. ? X Control Chart Control Chart ?For n=1, the MR control chart is also used to manage the process dispersion σ by using the moving range MR. ?The MR control chart is used when the number of the selected pads is equal to 1. ? MR Control Chart Process Capability Analysis Gaussian graph Analysis result Tolerance setting Tolerance setting dialog box ? Evaluate printer process capability for the selected pads – Shows distribution of measured data – Display analysis result : Mean, Sigma, Cp, Cpk, tolerance Process Capability Analysis ? Process Capability index : Cp – Reflect process variation against tolerance – Considers only process variation USL : Upper Specification Limit LSL : Lower Specification Limit LSL USL μ 6σ USLLSL Cp = 6σ USL LSL Process Capability Analysis ?
